Which one of the following statements is true regarding voluntary and involuntary responses? A. Voluntary responses control the activity of glands. B. Voluntary responses originate in the sensory receptors. C. Involuntary responses are part of the autonomic system. D. Involuntary responses may include the spinal cord and not the brain.

Answers

Answer:

The correct answer would be C. Involuntary responses are part of the autonomic system.

The autonomic nervous system (ANS) is sub-division of the peripheral nervous system (PNS) mainly associated with involuntary responses.

It regulates the psychological actions such as heart rate, respiratory rates, digestion, urination, sexual arousal, pupillary responses, thermoregulation, fight and flight responses et cetera.
Id say D, that responses may include the spinal cord but not the brain. 

A retrovirus is?a. is a primitive virus.
b. has a genome made of RNA.
c. has the simplest of all protein coats.
d. was discovered before any other virus.

How is the virus reproduced during the lysogenic cycle?
a. through reproduction of the host cell
b. by using viral enzymes to reproduce viral DNA
c. by using the cell's enzymes to reproduce viral DNA
d. by breaking the cell open and releasing new viruses

Answers

Ans. (b). has a genome made of RNA.

Retroviruses are viruses with RNA molecules as their genome. They insert a copy of their RNA genome into the host cell DNA and change the cell genome. These viruses are generally known as single-stranded positive-sense (+ strand) RNA viruses.

Examples: Human immunodeficiency virus and hepatitis B virus.

Thus, the correct answer is option (b).

Ans. (a). through reproduction of the host cell.

Lysogenic life cycle is a virus reproductive cycle that involves integration of viral nucleic acid into host's genome or formation of a replicon in host's cytoplasm.

The host cells (bacterial cells) remain alive and reproduce normally, so thus, viruses reproduce through the reproduction of host (bacterial cells).

Thus, the correct answer is option (a).

A retrovirus virus has a genome made of RNA. A virus during the lysogenic cyle is the reproduction through the host cell.

1. Explain how the oceans affect climate.

2. What factors determine Earth's climate?

Answers

Answer-Sea flows act a lot of like a transport line, moving warm water and precipitation from the equator toward the posts and cold water from the shafts back to the tropics. In this manner, sea flows manage worldwide atmosphere, assisting with balancing the lopsided dissemination of sun powered radiation arriving at Earth's surface.

Dr. Wilson is analyzing the similarities between the wing of a bat and the arm of a monkey. He is using _____.

Answers

The correct answer for the question that is being presented above is this one: "comparative morphology." Dr. Wilson is analyzing the similarities between the wing of a bat and the arm of a monkey. He is using comparative morphology. Comparative morphology refers to the analysis of the patterns of the locus of structures within the body plan of an organism, and forms the basis of taxonomical categorization.

B) comparative morphology is correct

A scientist wants to prove that certain chemicals in cosmetics are likely to cause harm to developing fetuses, when used by a pregnant mother. What is the most likely limitation she will face in her scientific design?limitations due to the time required to complete the experiment

limitations due to the system being too large to investigate thoroughly

limitations due to high expenses for equipment and supplies

limitations due to ethical concerns about experimental subjects

Answers

The answer is limitations due to ethical concerns about experimental subjects. Because the certain chemicals still need to be proved whether it is harmful. So they can not ensure the safety of the fetuses of this pregnant mother.
