adrenaline is the hormone which is directly controlled by nervous system
The right answer is C.
Classically positive interactions or facilitators between species are divided into two broad categories:
- those where the two partners involved benefit from each other: the mutualisms (symbolized by + / +)
- those where one of the two partners makes a profit or an advantage while the other gets nothing from it without being affected negatively: it is the commensalism symbolized by + / 0.
It may be that bacterial commensalism has an interest in its host (the animal) in the sense that it protects against parasites, or on the contrary, it favors their appearance.
The conditions listed above are common side effects of DEPRESSANTS. Depressants are drugs which slowed down the central nervous system an the brain. They are usually used to treat anxiety and sleep disorders. Other side effects of depressants include: slurred speech, impaired memory and judgement, lowered inhibition, etc.
Answer:
B
Explanation:
This involves selectively breeding two or more populations of a species or subspecies with desirable traits that are wanted by the humans. The offspring of the populations will bear the desired traits from the population. Breeding can be done over generations. An example is the breeding a cattle population that is resistant to drought and another that produces more milk. The filial generations will bear both traits.
