Answer:
Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. Of the four compartments the rumen is the largest section and the main digestive centre
The rumen. The rumen (on the left side of the animal) is the largest stomach compartment and consists of several sacs. It can hold 25 gallons or more of material depending on the size of the cow. Because of its size, the rumen acts as a storage or holding vat for feed.

D
Which group would represent the decomposer organisms?
1) A
2) B
3) C
4) D
Answer:
B
Explanation:
because that is the 2nd decompers
B group would represent the decomposer organisms. Therefore, the correct option is B.
What are Decomposers?Decomposers are organisms that convert decaying organic matter into more basic components. They are an important component of the nutrition cycle because they convert complex chemical substances, such as nitrogen and carbon, into direct nutrients that can be absorbed by plants and other living things.
Some species of bacteria, fungi and insects are specialized decomposers. These organisms are essential to maintaining healthy soil because they aid in the recycling of nutrients and the breakdown of organic matter, which would otherwise build up and cause nutrient imbalances. Decomposers, which break down dead organisms and aid in the containment of pathogens, may be important in disease prevention.
Therefore, the correct option is B.

The graphs here show the distribution of beak depths for the ground
finches on Daphne Major, an island in the Galapagos. The bird beaks were
measured over a multi-year study, including a time period before and after
a drought. The drought reduced the supply of seeds and left most of the
seeds as thick-walled nuts that survived the drought. Analyze the data and
select the claim about natural selection and genetic diversity that is
supported by the data.
Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select for the most fit phenotypes, as there was an
increase in average beak depth after the drought.
Natural selection tends to increase genetic variation, as there were more ground
finches after the drought, and it tends to select for the most fit phenotypes, as there
was an increase in average beak depth after the drought.
Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select against the most fit phenotypes, as there was an
increase in average beak depth after the drought.
Natural selection tends to increase genetic variation, as the average beak size
increased after the drought, but it tends to select against the most fit phenotypes, as
there was a decrease in population size for the finches after the drought
Answer: (A) Natural selection tend to reduce genetic variation as there was a smaller distribution of beak depths, but it tends to select for the most fit phenotypes, as there was an increase in average beak depth after the drought.
Explanation: The picture below shows proof if needed. On USATP
Natural selection tend to reduce genetic variation as a smaller allocation of beak depths, but it tends to select for the most fit phenotypes, as an increase in average beak depth after the drought.
How does natural selection affect genetic variation?Genetic variations that vary gene and protein role.
If a trait is favourable and helps the someone survive and breed, the genetic variation is more likely to be passed to the next generation.

A. graph 2 below
B. graph 3 below
C. graph 4 below
D. graph 5 below
Answer:
B. graph 3 below
D. graph 5 below
Explanation:
The original population of beetles (Graph 1) shows that most individuals had an intermediate phenotype between dark and light color. The graph expresses its highest point in the middle of the phenotypic ax, while the curve´s tails coincide with light and dark colors.
Probably, most of the trees inhabiting the whole island had some darkish color tone, which beetles used to camouflage and avoid predation.
When the company cleared the area and reforested, they planted light trees on one half and dark trees on the other half of the island. This change in the environment modeled the beetled phenotype, together with predation pressure.
If we consider the whole original population, we should say that it went under a disruptive selection. But if we think about the sides of the island separately, we could say that the population living on each side went under directional selection. We are not thinking about the whole population of beetled inhabiting the whole island, but two groups inhabiting each side of the island.
Graph 3 represents the beetles inhabiting the part of the land with dark trees. The population went under directional selection, and most of them turned into dark-colored to camouflage with the substrate in which they live.Graph 5 represents the beetles inhabiting the other part of the land with light trees. The population went under directional selection, and most of them became light-colored to camouflage with the substrate in which they live.Which scientist devised tests that helped confirm that bacteria and other microorganisms cause a variety of diseases?

If a drug was administered that would impede the binding of NAD+ to electrons what steps of cellular respiration would this substance affect
Answer:
The correct answer is - not getting all NAD+ so burning more ATP to make up for the energy loss.
Explanation:
If the drug was administered and it would cause impedetion of the binding of NAD+ to electrons which causes decrease availability of the NAD+ that leads to less energy formation due to the use up more ATPs in the process of cellular respiration.
If NADH couldn't be formed as NAD+ will not binding, the cells will lose out on ATP produced. It will lead to weight loss due to burning out more ATP to make up for the energy loss.

Which of the following describes a portion of the water cycle that is not driven by
gravity? O
(1 Point)
B) Precipitation of water that has condensed from clouds
D)Water seeping into the ground to enter an aquifer
C)Water flowing in a river toward the ocean
A) Evaporation of water from the ocean to form clouds
The correct answer is A. Evaporation of ocean water to form clouds.
Explanation
The water cycle is a series of physical-chemical phenomena in which water goes through three states (liquid, solid and gaseous). In this process, the water in a liquid state is evaporated becoming in a gaseous state, and rising towards the sky (against the force of gravity) forming clouds. Once in the clouds, the water condenses, going from a gaseous to a liquid state. After this process, the water precipitates by the action of gravity towards the earth where a process such as the filtration of water in the soil occurs, forming aquifers, the accumulation of water in the rivers that flow into the sea, the freezing of water on the snowy peaks of the mountains, among others. According to the previous explanation, the correct answer is A. Evaporation of ocean water to form clouds.
