Answer:

B

Explanation:

DNA replication is semiconservative- meaning the old template strand will form a double helix with the newly synthesized strand. The DNA polymerase can only replicate DNA in the 5’ -> 3’ direction on a DNA strand. However, because the two strands of a DNA double helix run antiparallel (and they are replicated together), then during replication, one strand will be oriented in the opposite direction (i.e 3’ -> 5’ direction).

Because DNA polymerase requires a primer to begin replication, the leading strand will require one primer, because replication on this strand occurs continuously. On the lagging strand, many primers are required because replication is done piecemeal forming fragments called Okazaki fragments. The fragments are later joined by DNA ligases.

DNA polymerase can only add nucleotides in the 5′ to 3′ direction, resulting in continuous synthesis of the leading strand and discontinuous, fragmented synthesis of the lagging strand known as Okazaki fragments.

The enzyme DNA polymerase works only in the 5′ to 3′ direction during DNA replication. This specificity affects how both the leading and lagging strands are synthesized. The leading strand is synthesized continuously in the direction of the replication fork because it aligns with the directionality of DNA polymerase. However, the lagging strand is synthesized in a discontinuous manner away from the replication fork, resulting in short stretches of DNA called Okazaki fragments. These fragments are later joined to form a continuous strand by the action of DNA ligase. As such, the correct answer to how DNA polymerase affects the leading and lagging strand is option B: DNA polymerase can work continuously on the leading strand but works discontinuously on the lagging strand, creating Okazaki fragments.

Answer:

Bacteria and Archaea

Explanation:

The prokaryotes are classified into two domains, the bacteria and the archaea domains. This makes them unique as the other organisms fall into one of the three domains, not in two of them. The prokaryotes come in many different shapes. They all do fall into three categories, bacilli (which are the rod-shaped prokaryotes), spirilli (which are the spiral-shaped prokaryotes), and cocci (which are the spherical shaped prokaryotes).

Prokaryotes are classified into two domains: Bacteria and Archaea. These domains include unicellular organisms without nuclei or other complex structures, but they differ in genetic composition and sequences, cell wall structures, and lipid composition.

The two domains that prokaryotes are classified into are Bacteria and Archaea. Both of these domains include unicellular organisms lacking a nucleus and other complex organelles, hence falling under the category of prokaryotes. However, they differ significantly in their genetic composition and sequences, cell wall structures, and lipid composition. For instance, bacteria have peptidoglycan in their cell walls, while archaea do not.

Bacteria, the most well-known and studied category of prokaryotes, are incredibly diverse in terms of habitats, ranging from human skin to hot springs to the deep ocean. On the other hand, Archaea are extremophiles, thriving in extreme conditions like high temperatures, salinity or acidity, where most other life forms cannot survive.

Explanation:

Producers absorb the disassembled organic matter found in soil to make their own food.

Answer:

B.they absorb it to make their own food

Explanation:

Producers are set of ecological organisms that have the ability to synthesize their own food via the process of photosynthesis. However, photosynthesis only produces the plant with organic food used to produce energy. The plant still needs other nutrients in form of elements to grow and develop.

These nutrients such as Nitrogen, Phosphorus etc. are obtained from the soil when decomposers like bacteria, breaks down organic matter releasing nutrients into soil. These nutrients are then absorbed by the roots of plants. The plants uses these nutrients to grow and develop important tissues needed to undergo its primary function of photosynthesis i.e making its own food.

capsule prevents the bacteria cell from engulfment by eukaryotic cells

The function of a bacterium's capsule is protection.

The bacterium's capsule encompasses any polysaccharide and / or protein surface layer (including the S-layer of eubacteria), but excludes the S-layers that make up the cell wall of archaebacteria.

The capsule protects the bacteria from phagocytosis, the main defense mechanism used by the host in the presence of capsulated bacteria.

An effective response to defend against this type of bacteria involves the production of antibodies that specifically bind to the capsule, facilitating opsonization and phagocytosis.

Therefore, we can conclude that the bacterium's capsule is generally polysaccharide in nature, it is an outer layer of material, which protects the bacteria from the desiccation of the environment.

Answer:

The correct answer is C: Yes, as long as use doesn't exceed availability.

Explanation:

Non- renewable resources cannot be used permanently, but these resources can be used sustain-ably over a period of time to meet their needs. The reason is that these non-renewable resources such as oil, gas, and fossil fuels, are being used at a larger rate, but their production is quite slow beneath the earth surface.

Therefore on the surface, it is not possible to use them sustain-ably except exceeding the limit as they are running out.

For example, in 19th-century whale oil was used to meet the energy needs, but gradually this species became distinct, and its population couldn't be protected and restored by human beings.

Answer: Unicellular and multi cellular organisms have some similarities and differences between them. The similarities between the two are listed below:

1.One big similarity between unicellular and multi cellular organisms is that the two of them are made up of cells.

2. The two organisms have similar genetic codes; both type of cells has DNA as hereditary material. The genetic code is universal and DNA sequence from a unicellular organism can be reproduced by a multi cellular organism and vice versa.

3. Both unicellular and multi cellular organisms have the same type of cell membrane. The cell membrane are made from phospholipids and they also incorporate different types of proteins.

4. Both organisms also have ribosomes in their cells. The ribosomes are responsible for the synthesis of proteins. Both cells synthesis proteins.

5. Both type of organisms have to obtain energy and nutrients to sustain their growth and energy.

Unicellular and multicellular organisms are similar as they all begin life as a single cell and can carry out all life processes essential for survival. However, unicellular organisms perform life processes independently, without the need for specialized cells while multicellular organisms have specialized cells performing specific functions, organized intricately into tissues and organ systems. Despite differences in complexity, all organisms showcase nature's incredible adaptability.

Unicellular and multicellular organisms share similarities despite their complexities of cellular organization. They are similar in the sense that, whether single-celled or multi-celled, all organisms begin life as a single cell, formed by the union of two cells, the ovum and the sperm. Moreover, all life forms exhibit a cellular structure and have the ability to carry out all life processes essential for survival.

Despite carrying out the same life processes, the way they do so differs greatly. Unicellular organisms have components functionally analogous to the organs of multicellular organisms, enabling them to perform functions similar to more familiar organisms. They are essentially independent-living, carrying out life processes such as metabolism and respiration without help from other cells.

On the other hand, multicellular organisms achieve life processes through division of labor. They have specialized cells that perform specific jobs. Furthermore, in multicellular organisms, different types of cells are produced, effectively organized into tissues, organs, and organ-system to form a complete organism. This requires a more complex developmental process.

Despite the difference in complexity, unicellular and multicellular organisms both show an extraordinary demonstration of nature's ingenuity and adaptability, showcasing their abilities to perform the essential functions of life in their unique ways.

Answer:viruses are on the borderline of love and non living. This they couldn't be concluded as singl cell organisms.

Explanation:

Viruses and eukaryotic cells differ in their structure, reproduction capabilities, and consideration as living organisms. Viruses have a simpler structure, can't reproduce independently, and are debated to be non-living. On the other hand, eukaryotic cells have a complex structure, reproduce on their own, and are certainly alive.

In comparing viruses and eukaryotic cells, one primary distinction is their structure. Viruses are significantly simpler, composed mainly of a protein shell surrounding their genetic material, which can be DNA or RNA. In contrast, eukaryotic cells are more complex. They contain multiple, specialized structures called organelles, including a nucleus that houses their DNA.

Additionally, viruses do not possess the cellular machinery necessary for reproduction. They must infect a host cell and usurp its reproductive mechanisms to replicate, adopt a parasitic lifestyle. This vital dependence on host cells for reproduction makes viruses obligate intracellular parasites. Eukaryotic cells, on the other hand, can reproduce on their own through processes such as mitosis and meiosis.

Ultimately, one of the most contentious differences revolves around the nature of life itself. Many scientists argue that due to their lack of key characteristics such as a cellular structure and the ability to reproduce independently, viruses should not be considered living organisms. Eukaryotic cells, by contrast, are undeniably alive as the foundational units of all large, multicellular organisms.

Answer:

rapid burial of vast amounts of vegetation

Explanation:

The organic matter is always decomposing, just that it depends on the conditions at what kind of a rate the decomposition will happen. If the climate is warmer and humid, then the decomposition is very quick. This results in a rapid burial of enormous amounts of vegetation. As the vegetation dies out, it piles up constantly, decomposes very quickly, and if there is something that can cover it, like mud for example, it will be buried in the ground. This is actually how the big deposits of coal have got the basis to form in the Carboniferous period.

The rapid decomposition of organic matter produces evidence which supports:

Answer:

Option D,  It requires energy

Explanation:

Active transport is a mechanism by which a substance move against the concentration gradient i.e from regions of low concentration to regions of high concentration. In order to do move against the gradient lot of energy is required which is pumped in by the energy molecule ATP produced during the cellular respiration.

While in other form of transportation i.e passive, a substance moves from the region of high concentration to the region of low concentration and hence no energy input is required.

a) The type of bear that would be selected for the coldest ecosystem would be the one with the thickest fur. Since the climate is changing in this scenario and it is becoming colder, the bears that have the allele for thicker fur would be the ones that would become more dominant through natural selection. The reason for that is that those bears will have an advantageous trait that will have them survive int he changing climate and environment.

b) Apart from the allele for thicker fur, the other allele that will accompany it would be the allele doe longer fur. In this way, by having both longer and thicker fur, the bears would have much better isolation from the cold weather, thus being able to function normally and not die out because of the severe cold. The alleles that would be becoming less common in the colder climate would be the ones for shorter and thinner fur, as they will not be suitable for the living conditions in which the bears have found themselves. These alleles would gradually decline, and that process is called natural selection.

c) As the climate will be getting colder and colder, the bear population will also change. The bears that will have the advantageous alleles will have an advantage over the other bears when it comes to survival. Because of this, they will be the ones that would be preferred for matting, as they will guarantee that the offspring will have those alleles too. The bear population will gradually start to become dominated by the bears with the alleles for longer and thicker fur, while the other bears will be in constant decline.

d) This scenario is an excellent example of natural selection. With the changing climate conditions, not all bears will be able to survive, but mostly it will be the ones with the alleles for thicker and longer fur. Apart from being able to survive without any particular problem, the bears with these alleles will be the ones that will be the preferable mating partners, thus the bears will start to select each other by advantageous traits, and push aside the ones that do not posses them. This is a prime example of how the natural selection works, as by selecting the mating partners, the bears are selecting who survives and who doesn't, gradually changing the population in the advantage of some of them, and disadvantage of the others.

Answer:

The right word to fill the blank space is TRANS MEMBRANE PROTEINS.

Explanation:

Membrane proteins are proteins that are found in the cell membranes of living organisms. There are three major types of membrane proteins, these are integral, peripheral and lipid anchored proteins. These proteins perform diverse functions in the transport of materials in and out of the living cells.

The integral proteins refer to those proteins that are permanently anchored to  the cell membranes. Integral proteins are attached to the cells in various ways, some integral proteins are attached to only one side of the membrane and do not span across the whole membranes while some span the whole phospholipid bilayers one or more times.  The integral membrane proteins that span the phospholipid bilayer one or more times are called TRANS MEMBRANE PROTEINS.

A membrane protein that spans the phospholipid bilayer one or more times is referred to as an integral or transmembrane protein. These proteins interact with the hydrophobic region of the phospholipid bilayer and can span a part of or the entirety of the membrane. Examples include channel proteins.

A membrane protein that spans the phospholipid bilayer one or more times is known as an integral protein or transmembrane protein. These proteins integrate completely into the membrane structure, interacting with the hydrophobic region of the phospholipid bilayer. Some of these proteins span only part of the membrane associating with a single layer, while others stretch from one side of the membrane to the other. They usually have a hydrophobic transmembrane segment that consists of 20-25 amino acids and can be found either on the surface or embedded within the phospholipid bilayer. Examples of such integral proteins include channel proteins, which serve as ion channels.

Fermentation is the process of lactic acid being formed when there is not enough oxygen present for cellular respiration to take place.

Therefore, fermentation is the correct term we are looking for.

The process in which lactic acid is formed when there is not enough oxygen present for cellular respiration to take place is fermentation. The correct option is c.

Lactic acid fermentation is a metabolic process that converts glucose or other six-carbon sugars (including disaccharides of six-carbon sugars such as sucrose or lactose) into cellular energy and the metabolite lactate, which is lactic acid in solution.

Lactic acid fermentation is a type of anaerobic respiration (or fermentation) in which sugars are broken down to produce energy in the form of ATP.

Because it occurs in the absence of oxygen, it is referred to as anaerobic. Lactic acid is produced as a byproduct of this reaction, giving rise to the name of this type of fermentation.

Anaerobic respiration occurs when human muscle cells do not receive enough oxygen. As a result, lactic acid fermentation occurs to produce energy molecules. Lactic acid is produced as a byproduct of this process.

Here is the full statement: A chemical reaction between iron atoms and oxygen molecules can only occur IF THERE ARE EFFECTIVE COLLISIONS BETWEEN THE PARTICLES OF THE TWO ELEMENTS.

Explanation:

Chemical reaction involves the re-arrangement of the particles that are present in the reacting substances. During the course of reaction, the particles of reactant are broken down and rearrange to form the products. For a chemical reaction to occur, the particles of reactants must be broken down and they must undergo effective collision. Effective collision between the atoms of iron and oxygen will give rise to the product, which is hydrated iron (lll) oxide. Without collision, chemical reaction will not occur and the product will not be formed.

Petroleum is one of the fossil fuels that originates from dead and decaying organisms in basins of deposition. For petroleum to form, several geologic,biologic and chemical factors must be accurately in place. These factors takes a huge amount of time in geologic time scale to form. The petroleum in the crust today formed several millions of years ago.

With this knowledge, petroleum is a non-renewable resource. It was central to the industrial revolution and the modern world was built around the oil industry. Exploration and production of petroleum provides oil for industrial and domestic use. Formation of petroleum takes millions of years and so, it is not renewable in our life time. It would take several years for the oil being used today to be replenished provided all the factors are in play.

This makes oil a limited resource constantly being depleted and not easily replenished.
