B. Fossil fuels is putting extra carbon monoxide in the air, affecting plant growth.
Answer:
Plant D
Explanation:
The control group is the plant that receives no treatment by the researchers, and is used as a "growth marker" for the others.
Answer:
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
Some differences among individuals in a population are due to genetics and are heritable.
- Despite without being aware of the existence of genes, Darwin could see that many characteristics are heritable—passed from parents to children.
- Mutations are structural alterations to the DNA molecules that make up genes. A significant source of genetic variation within a population is gene mutation.
- Variants that are inherited (or hereditary) are present in almost all of a person's cells throughout their lifetime and are passed from parent to kid.
- Due to their presence in the parent's egg or sperm cells, which are also known as germ cells, these variations are also known as germline variants.

Answer: Option A
Explanation:
Epilepsy can be defined as the medical condition in which the central nervous system disorder in which the brain activity becomes abnormal which results in the abnormal behavior, sensation accompanied by loss of awareness.
In this condition a drug that can best treat epilepsy should reduce the activity of neurons in the epileptic focus which are excitatory neurons based on the effect throughout their cortex.
It does so by increasing the threshold which is required to generate action potential which will decrease the chances that neurons will fire.
This effect will reduce the overall amount of excitation which spreads from epileptic focus throughout the cortex.
hence, the correct answer is option A
