The answer is B) whether the mutation makes some lizards more fit for their environment than other lizards.
<span>If a mutation introduces a new skin color in a lizard population and that </span>mutation makes some lizards more fit for their environment than other lizards then the frequency of <span>the new allele will increase. For example, if a mutation causes some dark skin color which can help some lizards to survive. The more lizards with dark skin color will survive, and after some time, the frequency of the new allele will increase.</span>
Answer:
A. Skeletal muscles
Explanation:
An effector is a group of cells, an organ, gland or any part of the body that acts to bring about a change in response to a nerve impulse from the CNS.
In the case of thermogenesis as stated in the question above, where a drop in temperature is detected by thermoreceptors in the CNS, the part of the body that responds in returning the body temperature back to its baseline are the skeletal muscles. The skeletal muscles are the effectors that responded in repeated contracions to generate heat.
Answer:
The way that plants create food using sunlight
Explanation:
The flow of energy in an aquatic ecosystem phytoplankton → zooplankton → fish → mammal.
<h3>What does the bottom-up model?</h3>
The bottom-up effect means that a lower trophic level in the biological network affects the community structure of higher trophic levels by means of resource restriction.
whereas the top-down effect refers to a higher trophic level that influences the community structure of a lower trophic level through predation.
Thus, opotion "B" is correct.

Answer:
Animals and humans depend on plants for many things, and without plants, there could be no life on Earth.
Explanation:
1. Plants are the primary producers. They are the only organisms that can make their own food. Animals, who are incapable of making their own food, depend on plants for their supply of food.
2.The oxygen that animals breathe comes from plants. Through photosynthesis, plants take energy from the sun, carbon dioxide from the air, and water and minerals from the soil. They then give off water and oxygen. Animals then use oxygen process called respiration. Respiration is the process used by organisms to release energy from food, and carbon dioxide is given off.
3.Plants also provide habitat for many species of animals. The plants provide food, shelter from weather (rain, sun), nesting place, sleeping ground and hideout from predators.
For example: Different animals live in different parts of the rainforest. Scientists divide the rainforest into zones based on the living environment.
