Answer:
D
Explanation:
The result of the cross is best explained by dominance.
According to Mendel, when the alleles that make up a gene are different and one of the alleles is dominant over the other, the dominant allele would mask the effects of the recessive allele.
In the same vein, when the alternate version of the same trait is dominant, such trait would be expressed over the other version in heterozygous state.
Assuming that the genotype of the brown rabbit is BB and that of the white is bb. When the two rabbits are crossed:
BB x bb
Bb Bb Bb Bb
All the offspring would be heterozygous and brown in color because the brown allele is dominant over the white allele.
Hence, the correct option is D.

what could cause a population to reach it's carrying capacity
Answer:
As competition increases and resources become increasingly scarce, populations reach the carrying capacity (K) of their environment, causing their growth rate to slow nearly to zero. This produces an S-shaped curve of population growth known as the logistic curve (right).

What affects wearing capability?Wearing potential, or the wide variety of individuals that an environment can sustain over time without destroying or degrading the environment is determined via some key elements: meal availability, water, and area.
How do you degree the carrying ability of a habitat?Wearing ability may be anticipated via calculating the total vicinity and an overall populace of that place.

Compare and contrast passive transport, active transport, and osmosis
Answer:
Passive transport moves molecules and ions from a higher concentration to a lower concentration without any energy while active transport does the same thing only it uses energy. Osmosis deals with the net movement of solvent molecules through a membrane with a higher solute concentration. Osmosis and active transport both work together, while osmosis does its own movement the active transport moves the dissolved solutes across a membrane against a concentration gradient.
Active transport and passive transport are almost the same they function the same only one doesn't require energy while the other one does. Hence why active transport and osmosis work well together it's because of the energy that helps transport dissolved solutes.

Why would an enzyme that is effective with one reaction have no effect on another reaction?
Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules.Answer:

Which of the four molecules has the highest amount of stored energy? Carbon dioxide water oxygen glucose
Answer:
Glucose
Explanation:
Glucose has the highest amount of stored energy that the others because glucose posses more chemical bonds which can undergo rearrangement as a result of chemical reactions. When the bonds are rearranged there is release of energy meaning that the bonds in glucose consist of stored energy. Water, carbondioxide and oxygen does not have much chemical bonds compared to glucose, hence they don't have stored chemical energy.

Predators Contribute to a Stable Ecosystem
In nature, energy flows in only one direction. Transfer of energy must occur in an ecosystem
because all life needs energy to live, and only certain organisms can change solar energy into
chemical energy. Producers are caten by consumers that are, in turn, caten by other consumers,
Stable ecosystems must contain predators to help control the populations of consumers. Since
ecosystems contain many predators, exterminating predators would require a massive effort that
would wipe out predatory species from barnacles to blue whales. Without the population control
provided by predators, some organisms would soon overpopulate,
Explain the phrase "only certain organisms can change solar energy into chemical energy," in the
underlined portion of the first paragraph. In your answer be sure to identify:
1)the type of nutrition carried out by these organisms
2)the process being carried out in this type of nutrition
3)the organelles present in the cells of these organisms that are directly involved in changing solar
energy into chemical energy
The phrase "only certain organisms can change solar energy into chemical energy," is about the plants which means producer organisms.
What is an example food chain?An example of this type of process is: plants generate their own food and are part of the feeding of insects, which are consumed by frogs. They serve as food for snakes, a source of nutrition for birds, which are consumed by decomposers.
Organisms of this level are classified as autotrophs, that is, they are living beings capable of producing their own food, not being necessary to feed on another living being. Plants and algae are organisms classified as producers.

Which of the following is a characteristic of all reptiles?
Select one:
a.

b.

c.
are fully aquatic
d.
are ectothermic
Answer:
D - Are ectothermic; (took the test)
Explanation:
Reptiles are cold-blooded, scaly vertebrates.
Reptiles are the Chordata that belongs to the animal kingdom and are covered with the scaly body. All reptiles are ectothermic or cold-blooded. Thus, option d is correct.
What are the characteristics of reptiles?Reptiles are the vertebrates that have backbones and scaly bodies hence Chordates. The dry skin of the reptiles is covered by scales and bony plates. They have four legs and have intermediate properties between mammals and amphibians.
They breathe through the lungs, and almost all reptiles lay eggs and hence are oviparous. They have cold-blooded metabolisms and hence are ectothermic. They regulate and maintain the internal body temperature according to the external environment.
Therefore, all reptiles are ectothermic (cold-blooded).
