Answer:
Four quanta of sunlight absorbed by each Photosystem to provide the energy to do this.
Explanation:
Because each molecule of oxygen released involves the flow of four electrons from two water molecules to two NADP+s and requires four quanta of sunlight absorbed by each Photosystem to provide the energy to do this.

after the mass extinction that occurred 65 million years ago mammals rapidly diversified to occupy habitats that were previously unavailable to them. What concept does this illustrate
Answer:
Diversity in organisms occur due to change in the environmental conditions of the earth.
Explanation:
This concept illustrate that diversity in organisms occur due to change in the environmental conditions of the earth. Changes occur in the physical features of organisms due to exposure to different types of environmental conditions. These physical features helps organisms to survive in that environment so we can conclude that diversification occurs in the organisms due to change occur in the environment.

Paul and Jessica are making a model of an animal cell. What should they show going into and out of the cell in their model?
Answer:
Water, carbon dioxide, and oxygen.
Explanation:
It's kind of like the lungs in your respiratory system! It takes in oxygen and submits carbon dioxide out. However, in this case, the cell membrane decides what can come in and what can't. Water, carbon dioxide, and oxygen are essential for cells which is why the cell membrane allows them to cross. This is what Paul and Jessica should show in their model.

Distinguish between tissue fluid and lymph
Answer:
Fluid found in the spaces around the cells. It comes from substances that leak out of blood capillaries. As new tissue fluid is made, it replaces older fluid, which drains towards lymph vessels. When it enters the lymph vessels, it is called lymph.

Your friend comes to you with a problem. It seems his shrimp boats aren't catching nearly as much shrimp as they used to. He can't understand why because he used to catch all the shrimp he could handle. Each year he added a new boat, and for a long time each boat caught tons of shrimp. As he added more boats, there came a time when each boat caught somewhat fewer shrimp, and now, each boat is catching a lot less shrimp. Which of the following topics might help your friend understand the source of his problem?
A) density-dependent population regulation and intrinsic characteristics of population growth
B) exponential growth curves and unlimited environmental resources
C) density-independent population regulation and chance occurrence
D) pollution effects of a natural environment and learned shrimp behavior
E) a K-selected population switching to an r-selected population
The correct answer is A. Density-dependent population regulation an intrinsic characteristic of population growth.
Explanation
Density-dependent population regulation includes factors such as diseases, predation, or competence that limit the growth of a population depending on the size of it (density). In the case presented, predation is the factor that affects the shrimp population because more boats and more shrimp imply more predation from humans. Additionally, this excessive predation limits the growth of the shrimp population and causes the depletion of shrimp over time. According to the above, the correct answer is A. Density-dependent population regulation an intrinsic characteristic of population growth.
5. On the rock shoreline, how was biodiversity affected by the removal of starfish?
Answer:
When the starfish have been removed experimentally, the mussel populations have expanded rapidly and covered the rocky intertidal shores so exclusively that other species cannot establish themselves.
Explanation:
Reproductive isolation occurs when
A- some catastrophic event greatly reduces the size of the population
B- The gene pool of different populations have become very diversified
C-members of different populations can no longer meet successfully
D-small numbers of individual moves and starts in new population
Answer:
The correct answer is - C. members of different populations can no longer meet successfully.
Explanation:
Reproductive isolation is the process that occurs when two or more species or populations are not able to interbreed. The mechanisms or properties that are used to preventing individuals of separate species from mating called Reproductive isolation mechanisms.
The different barriers can cause this reproductive isolation such as different mating seasons. These barriers could be behavioral or temporal or ecological isolations.

What is biological hierarchy?Biological hierarchy refers to the organization of living organisms into a series of levels, each level being more complex than the one below it. The biological hierarchy begins with the smallest unit of life, which is the cell, and progresses upward to include tissues, organs, organ systems, organisms, populations, communities, ecosystems, and ultimately the biosphere.
Each level of the biological hierarchy is characterized by different properties and interactions. For example, cells are the basic unit of life and perform all the essential functions of an organism. Tissues are groups of cells that work together to perform a specific function, such as muscle tissue, which is responsible for movement. Organs are structures made up of tissues that work together to perform a specific function, such as the heart, which pumps blood throughout the body.

In a chemical reaction if the reactants are heated the reaction usually happens
Faster
Slower
Same Rate
Ina smaller volume
Explanation:
In a chemical reaction, if the reactants are heated, the reaction usually happens faster.
If the reactants are heated the reaction usually happens faster.
Chemical reaction
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. The reactants are usually converted to a new product entirely.
The rate of reaction or speed of reaction for a reactant or product is defined as how fast or slow a reaction takes place.
The reaction is always faster at higher temperature. Chemical reactions typically occur faster at higher temperatures.
Since the reactants is heated, the temperature is also increased which invariably leads to higher temperature.
Therefore, if the reactants are heated the reaction usually happens faster

Answer:
The correct answer is - stones.
Explanation:
Kidney stones are medically called renal calculi or urolithiasis. These are normally hard and very small minerals and salts made stones that deposites inside your kidneys. Kidney stones can be formed due to several reasons such as an unhealthy diet with higher salt, soda, and sugar constituents, high dose of minerals, dehydration, or less drinking water
To decrease the risk of forming kidney stones or if one is experiencing kidney stone should drink enough water which helps to remove formed or forming deposits of minerals.
Answer:
Kidney stones.
Explanation:
Kidney stones are stone-like solid structures that are formed with tiny crystals.
Kidney stones are known by many alternative names such as Nephrolithiasis, Renal calculi, Cystine - stones, and more.
The kidney stones are caused by dehydration in the body or lack of drinking enough water. Other causes include a high level of protein, calcium, sugar, salt, or soda in the body.
