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.

How is your day going?
Explanation:
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.

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.

Solid, crystal-like substances that are formed in the kidneys due to not drinking enough water or high levels of protein, sodium, soda, sugar or calcium are called kidney ________. *
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.
Therefore, the correct answer is kidney stone.
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

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.

What factors influence the survival of Kangaroos in its natural habitat?
Answer:
Kangaroos from desert and semi-arid environments have adapted to drier conditions and have several features that help them deal with the lack of water. Kangaroos need very little water to survive. Kangaroos hop over large distances to find food and water. Hopping is a fast, energy efficient way to travel. Kangaroos need very little water to survive and are capable of going for months without drinking at all. The kangaroo usually rests in the shade during the day and comes out to eat in the late afternoon and night when its much cooler. It eats mostly grass. It needs very little water to survive.

What happens to the amount of energy that is used up during photosynthesis?
A. It changes to an equal amount of chemical energy.
B. It changes to a lesser amount of chemical energy.
C. It changes to a higher amount of solar energy.
D. It changes to an equal amount of solar energy.
I need this like ASAP im in the test right now
Answer:
B
Explanation:
It changes to a lesser amount of chemical energy. ... It forms from an equal amount of potential energy. It forms from an equal amount of radiant energy.
The amount of energy that is used up during photosynthesis changes to a lesser amount of chemical energy. That is option B.
What is photosynthesis and it's effects?Photosynthesis is the process by which green plants that posses chlorophyll traps in energy from sunlight and uses it to convert solar energy to chemical energy which is the form of energy that is useful for living organisms.
This is carried out by the absorption of light by the green pigment, chlorophyll. This helps in the splitting of water molecules which further react with carbon dioxide to form sugar
Therefore, the amount of energy that is used up during photosynthesis changes to a lesser amount of chemical energy because of the sugar that is produced as by product.

Explanation:
Two humans mate who are heterozygous for earlobe shape where attached earlobes (A) are dominant to free earlobes (a), and earwax quality where dry earwax (e) is recessive to wet earwax (E ). What is the probability that their first child will have dry earwax and attached earlobes
Answer:
3/16
Explanation:
This question involves two different genes coding for earlobe shape and earwax quality. The alleles for attached earlobes (A) and wet earwax (E) are dominant over the alleles for free earlobes (a) and dry earwax (e).
According to this question, two humans mate who are heterozygous for both genes i.e. AaEe × AeEe. Each parent will produce the following gametes: AE, Ae, aE, ae.
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
* Attached earlobe, wet earwax (A_E_) = 9/16
* Attached earlobe, dry earwax (A_ee) = 3/16
* Free earlobe, wet earwax (aaE_) = 3/16
* Free earlobe, dry earwax (aaee) = 1/16
Hence, the probability of these parents having their first child with dry earwax (ee) and attached earlobes (A_) i.e. genotype A_ee is 3/16.
Organisms are classified as producers or consumers according to the way they *
(1) obtain energy
(2) release wastes

HOW DO THE OCEANS CURRENTS AFFECT CLIMATE
Answer:
Explanation:
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
