Which of the following will not affect homeostasis in a multicellular organism

a: amount of light present

b: external temperature

c: both a and b

d: none of the above

The correct answer is option D (none of the above).

Explanation:

Homeostasis is the ability of an organism to regulate its internal stability while adjusting to the environment for functioning and survival. This is a defining feature of an organism.

1. The body temperature of organisms is an example of homeostasis like humans which maintains its temperature at 37 °C (98.6 °F) but it can be affected by various factors like exposure to high and low temperature, diseases.

2. The body temperature of cold blooded animals fluctuate in response to temperature of environment but they maintain their body temperature by moving in sunlight to warm their bodies during winter and and by hiding themselves form sunlight during summer.

Thus, option D is the correct answer.

1: the largest region of the brain is the:

  cerebrum

2. the term "psychology" literally means:

the process or procedure of the science or study of the mind.

3. the area of the brain responsible for respiration, heart rate, and smooth muscle control of our blood vessels is t

medulla oblongata

4. the structure that conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain is the:

spinal cord

5. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

meninges

6. the cord-like (string-like) structures that carry bio-electrical impulses from one part of the body to another are called

nerves

7. a group of nerve cell bodies that are found outside of the spinal cord and brain are referred to as:

ganglions or ganglia (pl.) “literal meaning knot”

8. the term that means spinal cord inflammation is:

myel/itis

i believe the correct answer is d
