Answer:
Autonomic nervous system.
Explanation:
Autonomic nervous system may be defined as the division of the peripheral nervous system. Autonomic nervous system has been divided into parasympathetic nervous system and sympathetic nervous system.
The autonomic nervous divides is involved in controlling the respiration activity, digestive system and cardiovascular activity. This efferent nervous system controls the different type of the muscles like cardiac muscle, smooth muscle and the functioning of glands.
Thus, the answer is autonomic nervous system.
Answer:
The correct answer is - 6.5 to 7.5 pH.
Explanation:
The proper acidity or alaklinity or pH of an environment affect the growth of the microbes. The most suitable pH value for the most of the microbes are between 6.5 to 7 pH.
Most bacteria influences bacterial growth positively around neutral pHvale which is 6.5 to 7.5. However, some present in acidic nature called acidophiles as they can tolerate pH value of 1.
Thus, the correct answer is - 6.5 to 7.5 pH.
Answer: Most viruses can use host machinery to produce more of themselves
Explanation:
Since viruses carry out no metabolism themselves, they rely solely on the living cells of the host (organism they infect) to replicate and spread from cell to cell.
Thus, viruses do not kill the cells they infect since they need them, and use them to replicate more offsprings
Answer:
The organisms have a common ancestor
Explanation:
Homologues structyres conclude that organisms of different species share structures, making them all have some sort of common ancestor
