What is the answer to this question and the solution to it

Answer:

all of them.

Explanation:

biodiversity is good for any ecosystem.

Final answer:

Biodiversity is essential for all ecosystems, providing ecosystem services that include pollination, nutrient recycling, and the maintenance of soil health. It enables ecosystems to be productive and stable, ultimately supporting human life by providing food, medicinal resources, and clean water. Loss of biodiversity can lead to ecosystem degradation and threaten these vital services.

Explanation:

All ecosystems need biodiversity to maintain their health and stability. Biodiversity includes different levels such as species diversity, genetic diversity, and ecosystem diversity. High biodiversity, as seen in coral reefs and rainforests, provides numerous ecosystem services such as pollination, nutrient cycling, pest control, soil development, and maintenance. These ecosystems function effectively and support the vast array of life, including human life, by providing food sources, medicinal compounds, and clean water.

Biodiversity plays a critical role in nutrient cycling, where a variety of soil organisms contribute to nitrogen fixation and nutrient recycling. It enables plants to be pollinated and decomposers to recycle waste material. The genetic diversity within populations is crucial for their ability to adapt to changes, whether they be environmental shifts or emerging diseases.

The loss of biodiversity can lead to the degradation of these ecosystem services, making food production more expensive or even impossible, and reducing the soil productivity due to the loss of ecosystem interactions. Therefore, preserving biodiversity not only sustains our ecosystems but is vital for the long-term survival of humanity.

in Eukaryotic cell the organelle which holds the DNA is the nucleus. however, some part of DNA can also be found in mitochondria and chloroplasts.

Final answer:

The organelle in eukaryotic cells that holds the DNA is the nucleus.

Explanation:

The organelle in eukaryotic cells that holds the DNA is the nucleus. The nucleus is the largest organelle in a eukaryotic cell and is considered to be the cell's control center. It contains most of the cell's DNA, which is organized into chromosomes, and is responsible for regulating gene expression.

Hi there!

The answer is: March.

Because it's daylight savings so there would be equal sunlight in the Northern and Southern Hemisphere's.

Answer:

The answer is March.

Explanation:

The current month is March. This is called the March equinox.

A location in the northern hemisphere is currently experiencing equal sunlight as another location in the southern hemisphere. This is called the March equinox.

During the March equinox, the Sun crosses the celestial equator from south to north.

This happens on March 19, 20, or 21 every year.

The correct answer is - mass extinction.

The most dramatic extinction of large prehistoric mammals occurred when the ice age was ending. The climate suddenly changed dramatically, thus the environment changed very quickly in response. Also, there's indications that maybe a meteorite hit Greenland and caused dramatic changes in just few hours and days. The larger mammals were all very specialized animals, so even small changes in the environment are fatal for them, as seen in this case.

It is interesting though that only the megafauna died out, while the medium sized and smaller animals survived, largely because they are not very specialized but are much more opportunistic in their food choices. Some of the large mammals that died out in this period are the smilodon, homotherium, american lion, short-faced bear, mastodon, mammoth, American horses, American camels, giant sloth etc.

It would be A send a space probes to mars to study the surface like the NASA's Mars Exploration Rover (MER) mission was a robotic space mission involving two Mars rovers, Spirit and Opportunity, exploring the planet Mars.

Answer:

A is correct!

Explanation:

Answer:

B) protein synthesis

Explanation:

An RNA codes for protein synthesis. A triplet of nucleotides/bases in RNA helps in adding an amino acid into the protein strand. This triplet of nucleotides is knwon as codon and helps in adding amino acid which is specific to it. For example, AUG triplet codes for methionine while UGG codes for tryptophan. The amino acids get added in protein strand unless a stop codon is reached. Triplets UAA, UAG & UGA are stop codons.  Here it may be noted that initially a polypeptide chain is synthesized by RNA but the ultimate goal of making that polypeptide chain is protein synthesis.

Answer: The correct answer is -

B) protein synthesis.

Explanation:

RNA (ribonucleic acid) contains codon (a sequence of three nucleotides that code for particular amino acid) sequences that help in the process of protien synthesis (translation).

The genetic information is transferred particularly from mRNA to proteins at the site called ribosomes.

tRNA (transfer RNA) molecule arrives at ribosome with specific amino acid according to the codon present in the mRNA.

In this way, a long chain of amino acids is assembled to form proteins.

Thus, option B) is the right answer.

Final answer:

The true statement about heating up air in the lower atmosphere is that it happens to a different extent over land and water, mainly through the process of convection. This variation is due to the differing specific heats of land and water, and the role of latent heat through evaporation and condensation, demonstrating the complexity of atmospheric heating.

Explanation:

The statement C. It happens to a different extent over land and water is true about heating up air in the lower atmosphere. This variation is primarily due to the specific heat of land and water, and the process of convection. The land heats and cools more quickly than water, leading to differences in air temperature above these surfaces. This is evident in coastal areas where daytime and nighttime temperatures can vary widely compared to areas near large bodies of water which experience more moderate temperature changes. Convection plays a key role in this process as the warm air from the earth's surface rises and cools, and cooler air sinks, creating a convection current that is the primary method of heat transfer in the atmosphere.

Additionally, latent heat also contributes to the heating of the air through the processes of evaporation and condensation. When water evaporates, it absorbs heat from its surroundings, cooling the surface. Conversely, when water vapor condenses into liquid, it releases latent heat, warming the air. These processes are intertwined with convection to regulate temperatures in the lower atmosphere, further illustrating the complexity of atmospheric heating and its dependence on various factors, including geography and surface materials.

The answer is valves.

Heart valves have a particularly important role in keeping blood flow in a certain direction, allowing blood to flow from the atria to the ventricles and from the ventricles to the heart. Valves control the flow of blood through the heart by opening and closing each time the heart contracts. The valve's opening and closing functions are controlled by the pressure difference between the heart chambers and some muscles in the heart.

In case of dysfunction of one of these valves can be made an artificial heart valve or a mechanical type

The valves. They pump blood throughout the body and the transfer it to where you need it to go.

Answer:

A) mitochondria

Explanation:

Prokaryotic cells are the ones that lack membrane-bound well define the nucleus. They also lack the membrane-bound organelles such as mitochondria, Golgi apparatus, etc. These cells have a cell membrane and their DNA is present in the cytoplasm in the nucleoid region. So, a primitive anaerobic prokaryotic cell can not have mitochondria which are a characteristic feature of eukaryotes.

Fewer cheap China goods means fewer goods available to buy and therefore more expensive local goods. I'll have less available to buy and they will cost me more.

Answer:

The answer is: Blocking of low cost goods, involves a change to the purchase of high cost, and instead of more quantity of goods, the amount is these, also decreases.

Explanation:

A blockade in the trade on low-cost products would mean that the offer would become high-cost products, which would lead to buy less things for a higher price, while with low-cost products, more things can be bought at less price .

The answer is: Blocking of low cost goods, involves a change to the purchase of high cost, and instead of more quantity of goods, the amount is these, also decreases.

C. Water is a polar molecule.

C) it makes the molecule polar.

The  water molecule affects its charge by making it uneven. In the combination of hydrogen and oxygen, which makes up water, the oxygen atom has a slight negative charge and the hydrogen atoms have a slight positive charge. This gives the molecule a neutral charge as a whole, but it also means that water is a polar molecule.

Answer:

an organism remove its waste through some organs like skin ,lungs and kidneys while in cells the waste is broken down by lysosomes

Explanation:

Final answer:

Cells, the basic units of life, conduct necessary functions such as nutrient intake, waste excretion, and reproduction. Multicellular organisms have specialized structures from cells to organ systems for these tasks, while single-celled organisms rely on their lone cell to perform all functions.

Explanation:

Comparison Between Cellular and Organismal Functions

Cells are the basic building blocks of all organisms, engaging in various activities such as taking in nutrients, excreting wastes, growing, reproducing, and responding to the environment. Single-celled organisms must perform all essential processes independently, whereas in multicellular organisms, such as humans, specialized cells, tissues, organs, and organ systems collaborate to perform functions, including waste elimination.

In multicellular organisms, cells form tissues which group into organs, and these are further integrated into organ systems that work together to maintain the organism. For example, in the human body, the circulatory system, which includes the heart and blood vessels, is responsible for transporting blood and removing metabolic waste products from cells.

Comparing this to single-celled organisms, they rely on their single cellular structure to manage all these tasks through structures such as the cell membrane and organelles. Both multicellular and unicellular organisms ultimately follow similar life processes but achieve them through varied organizational complexities.

The best example of a population is 'all of the red foxes in a forest' because a population consists of individuals of a species in a specific area. A plant requires abiotic factors like moisture, oxygen, and minerals to survive, indicating its reliance on non-living parts of the environment.

The best example of a population is a. all of the red foxes in a forest. This is because a population refers to all the individuals of a species living within a specific area. For instance, all the pine trees in a forest would represent the population of pine trees within that ecosystem, just as all red foxes in a forest would represent the red fox population there.

In regard to the plant described, the statement shows that a living organism depends on abiotic factors. Abiotic factors are the non-living parts of an organism's environment, which in the case of the plant include moisture, oxygen, carbon dioxide, light, and minerals. These elements are critical for the survival of most plants and are not considered symbiotic relationships, which involve interactions with other living organisms, or biotic factors which are the living components of an environment.

Apoptosis is a programmed cell death mechanism that occurs when a cell is damaged or unnecessary. It allows cells to die in a controlled manner, preventing the release of harmful substances. Examples of apoptosis include amphibian metamorphosis and the elimination of unneeded cells during embryological development.

Apoptosis is a programmed cell death mechanism that occurs in organisms when a cell is damaged, unnecessary, or potentially harmful. It allows cells to die in a controlled manner to prevent the release of harmful substances. Examples of apoptosis include amphibian metamorphosis and the elimination of unneeded cells during embryological development. In T-cell development, apoptosis helps remove potentially dangerous cells that bind to 'self' proteins.

Answer:

c...

Explanation:

Question 9: The right answer is B (the second one)

The two major types of cellular, prokaryotic and eukaryotic organisms.

* Prokaryotes are identified with bacteria: most live as single-cell organisms but some bacteria associate in a chain. Prokaryotes have their DNA in the cytoplasm of the cell.

* Eukaryotes have a nucleus, a compartment separated from the rest of the cellular contents, which contains the DNA.

Question 17: The right answer is incomplete dominance.

Incomplete-dominated genetic action is a type of genetic action where one of the alleles outweighs the other in the production of qualitative phenotypes, without the dominant allele completely overshadowing the heterozygous recessive allele. Two copies of the dominant allele are required to produce the dominant phenotype. Since the recessive allele can perform its function at the heterozygous stage, this genotype produces a phenotype (the heterozygous phenotype) which differs little from the dominant phenotype.

In our case the phenomenon of incomplete dominance gave a pink color (between white and crimson) instead of crimson color when the white flowering plant was mixed with the crimson flower plant.

Question 19: The right answer is Speciation occurs gradually.

Speciation is a term that means the formation of new species.

Gradualism is an evolutionary theory according to which new species occur by gradual transformation of ancestral species, by evolution.

These transformations are slow and regular. Otherwise expressed: evolutionary theory according to which speciation is gradually effected by small successive changes over long periods.
