Final answer:

Prokaryotes predate eukaryotes according to the endosymbiotic theory which posits that eukaryotic cells evolved from prokaryotic cells forming symbiotic relationships. This theory is supported by the presence of prokaryote-like DNA in organelles like mitochondria and chloroplasts and fossil evidence that suggests prokaryotes were already present on Earth billions of years before eukaryotes evolved.

Explanation:

Scientists believe that prokaryotes existed earlier than eukaryotes based on the endosymbiotic theory, which suggests that eukaryotic cells evolved from a symbiotic relationship between two or more prokaryotic cells. This is further supported by mitochondria and chloroplasts having their own DNA similar to free-living prokaryotes and features such as double membranes and genes that are more closely related to those found in prokaryotes. According to the endosymbiotic theory, these organelles were once independent prokaryotic organisms that became permanent residents within larger host cells, leading to the evolution of eukaryotes. As eukaryotic cells are now known to possess complex internal structures and organelles, which presumably evolved through these endosymbiotic events, it is logical to infer that simpler prokaryotic cells predated them. The first eukaryotic cells are thought to have evolved about 2 billion years ago, much later in Earth's history compared to the ancient lineage of prokaryotes.

Photosynthesis is defined as the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Photosynthesis is defined as the process used by plants and other organisms to convert light energy into chemical energy, which is then released through cellular respiration to fuel the activities of the organism. The chemical energy which is stored in the form of sugars, which are created from water and carbon dioxide.

In this process green plants and some other organisms convert light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into organic compounds rich in oxygen and energy.

Thus, Photosynthesis is defined as the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Answer:

The correct option is A) Living things respond to their environment.

Explanation:

All living things tend to respond to the environment in some way or the other. When any change arises in the environment, it acts as a stimulus for the organism. A response is generated by the organism by detecting this stimulus.  For example, the weather is an environmental condition. When the weather becomes unfavourable for birds, they fly o the south where the weather conditions are better so that they can protect themselves from the excessive cold weathers. Such practices allow organisms to survive on the Earth.

The Correct Answer is A

Broader categories based on genetic links

Explanation:

Answer:

The answer is "Solute molecules move across a cell membrane from areas of higher concentration to areas of lower concentration."

Explanation:

Simple diffusion specifically involves the movement of (small, uncharged) solutes across a cell membrane. Since diffusion is part of the passive transport umbrella, it also requires no energy since the solutes move down the concentration gradient - from areas of high concentration to areas of low concentration.

Hope that helps! :)

Solute molecules move across a membrane from areas of higher concentration to lower concentration is called diffusion. Therefore, option A is correct.

A chemical diffuses when it moves from one location of high concentration to another area of lower concentration. When gas and liquid particles randomly collide and disperse, diffusion takes place.

Diffusion aids in the flow of materials into and out of cells. Until the concentration is the same everywhere, the molecules travel from a region of higher concentration to an area of lower concentration. Diffusion occurs in gases and liquids because random molecular movement is a possibility.

Diffusion is the process by which solute molecules travel across a cell membrane from regions of higher concentration to regions of lower concentration. Therefore, option A is correct.

Higher glucose concentrations usually lead to more ATP being produced due to more fuel for cellular respiration. However, actual ATP levels depend on various factors, including the cell's energy needs and current ATP and ADP concentrations. A feedback mechanism also exists to prevent overproduction of ATP when it's already abundant.

The relationship between the concentration of glucose in the culture medium and the ATP concentration in cells is quite direct and can be understood through biological processes involved in cellular energy production. Glucose is the primary energy source for cells, and it is broken down through a process known as glycolysis to produce ATP, the energy currency of the cell.

As glucose concentration increases in the culture medium, more glucose is available for uptake by cells. This glucose is moved down a concentration gradient into the cell through facilitated diffusion using carrier protein channels. Inside the cell, glucose is broken down by glycolysis, transferring some of the energy in glucose to ADP to form ATP. Thus, an increased glucose concentration typically leads to increased ATP production, as there is more fuel for cellular respiration.

However, it's important to note a feedback mechanism in which high ATP levels can inhibit further ATP production, thereby preventing wasteful use of resources when ATP is already in abundant supply. In contrast, increased levels of ADP compared to ATP can trigger the cell to produce more ATP through glucose catabolism. Therefore, while a higher glucose concentration generally enables greater ATP production, actual ATP levels in cells depend on multiple factors, including the cell's energy needs and existing ATP and ADP levels.

Explanation:

Endosymbiotic Theory:

The endosymbiotic theory helps explain the origins of multi-cellular organisms. An endosymbiont is defined as an organism that lives inside another organism in a state of "endosynmbiosis." The theory states that some of cellular organelles were originally separate prokaryotic organisms engulfed by an amoeba like organism. These engulfed prokaryotes sustained inside the amoeba and evolved into present day mitochondria and chloroplasts.

Apart from the aforementioned similarities, mitochondria and chloroplasts are roughly the same size as a prokaryotic cell and can self replicate by binary fission.

Answer:

Photosynthesis and cellular respiration are complementary processes because the reactants of one are products of the other, and vice versa.

Explanation:

Complementary processes are like opposite processes. Take a look at the equations for each:

Photosynthesis:

carbon dioxide + water + (light) energy => oxygen + sugar

Cellular respiration:

sugar + oxygen => carbon dioxide + water + (ATP) energy

Written as a word equation, it is easier to see that they are basically backwards. The main difference is that photosynthesis uses light energy and cellular respiration produces ATP energy, but both are energy in general.

Photosynthesis and respiration are two complementary processes. This is because the products of photosynthesis are used during the respiration process, and the products of respiration are used in photosynthesis.

---------------------------------------

Let us analyze the relationship and differences between the two processes.    

• Photosynthesis occurs in chloroplasts, while respiration occurs in mitochondria.

• The photosynthetic process needs solar radiation to produce organic compounds.

        The respiration process uses these organic compounds to obtain chemical energy.

• Photosynthesis transforms CO₂ into organic compounds, while respiration transforms organic compounds into CO₂.

• In the process of photosynthesis, it occurs a release of oxygen.

       Oxygen is then used during the respiration process.  

• Both processes are part of the carbon biological cycle.

• Both processes use electron transport chains to capture energy, which will be used in other cellular reactions.

• Respiration´s final products are CO₂, ATP, and water

• Photosynthesis´s final products are carbohydrates, oxygen, ATP, and NADPH.

These relationships can be established between cells of autotroph and heterotroph organisms.

Three properties that interact to produce weather are water pressure, air pressure, and latitudinal location.

Explanation:

Throughout the year we experience different types of weather conditions, and these conditions can be influenced by three main factors.

• Water cycle or water pressure: When sun rays falls on earth, the water from lakes and oceans turns into water vapor which in turn forms clouds and comes back into the form of rain.

• Air masses: It so happens that the air pressure is determined by the temperature above which it moves. For example: if it is above the area which experience snow then air mass will be cold and dry, similarly on hot areas it will be warm thus giving rise to different climatic conditions.

• The latitudinal location: The temperature mostly depends on its latitudinal location.

The Empire of Great Britain had a "global power," which was also known as a "superpower" concerning resources, influences and geopolitical landscapes.

Explanation:

When it comes to international relations, the power of a country or a nation is very important. It is an inherent goal that many people want. It can be used in many situations such as cooperating with other countries, coercing people to follow a rule, securing the nation and developing the nation, etc.

The Empire of Great Britain was considered, together with USA and the Soviet Union, to have a "superpower." Only the strongest nation possess such power. It was able to control millions of people, which then resulted into a great expansion. The reason behind this is that they had a stricter rule than other nations and people followed it. This made them stronger and while they continued expanding, they were able to acquire more resources.

The density- independent limiting factors that can affect a population include food, predation, toxic waste and environmental disasters.

Explanation:

Density independent factors like natural calamities which include volcanic eruptions, hurricane, floods, earthquake, etc are not influenced by population density change. For example, the current rampaging bush fire in Australia has caused a lot of damage to different animal and plant species. Many populations of species have become endangered and others are wiped off.

The quality of nutrients available in an environment affect the growth of organisms in it. The lower the quality of nutrients, the higher is the environmental stress. E.g in Lake Erie, the growth of algae was restricted due to the extensive presence of phosphorus in the water bodies.

Pollution is also a big reason for decrease in the density of populations. E.g Amphibians such as toad, frog are susceptible to pesticides which flow into the water bodies. It reduces their ability to reproduce and inhibits their growth.

When the number of predators in a given area increase, the population of prey decreases. Extensive predation can lead to the extinction of prey species.
