Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds.

Specialized ganglionic sympathetic neurons that release hormones into the bloodstream are found within the adrenal glands.
<h3>
What is adrenal gland?</h3>
- A little gland that produces noradrenaline, adrenaline, and steroid hormones.
- These hormones assist in maintaining healthy blood pressure, heart rate, and other vital bodily functions.
- Immune system, blood pressure, stress response, metabolism, and other critical processes are all controlled by hormones that are produced by adrenal glands.
- The cortex and the medulla, the two components that make up an adrenal gland, are each in charge of manufacturing a separate hormone.
- Problems with one, both, or other glands, such as the pituitary gland, can result in diseases of the adrenal glands.
- When the adrenal glands create either an excessive amount of hormones or an excessive amount of hormones from external sources, several diseases may arise.
- Since the adrenal glands are essential for human survival, if both are destroyed, the patient will need to take drugs and hormone supplements.

Answer:
a. The allele for round seeds is dominant to the allele for wrinkled seeds.
Explanation:
Mendel found that when two pure breeding plants that differ from each other with respect to one genetic trait are crossed, all the progeny express the phenotype of one parent. The phenotype of the other parent is not expressed in the progeny. He concluded that the genetic trait that is expressed in the F1 generation is dominant over the other which is masked in this generation.
A cross between pure breeding plants for round seeds and the wrinkled seeds obtained all the round seeded progeny. This meant that the phenotype "round" was dominant over the phenotype "wrinkled". If the allele "R" gave round phenotype and the allele "r" imparted wrinkled phenotype, the allele "R" was dominant to the "r".
Answer:
The right answer is A
Explanation:
Because animals take in sugar and oxygen, break them down and release carbon dioxide and water along with ATP as usable energy.
