1. Interstitial fluid directly influences the proper functioning of cells.
2. Effector refers to the structure of a feedback system, which gets output from the control center.
3. Receptor refers to the structure of the feedback system, which donates input to the control center.
4. Childbirth refers to the condition not regulated by a negative feedback loop.
5. Sign refers to the change in the function of the body, which can be determined objectively.
6. The cranial cavity refers to the large, bean configured cavity occupying the majority of the upper skull where the brain is situated.
7. The thoracic cavity compries of the lungs and is located in the mediastinum.

I have some doubt in Question no 9.
In biology, evolution is the change in the inherited traits of a population from generation to generation.
Common traits that have evolved in creatures are multicellular, heterotrophic, obtaining their energy by consuming energy-releasing food substances, reproduction and changes in cell structures.
Hey there!
Stimulus names the change in the environment that causes an organism to change its activity.
This means your answer is Option D.
Hope this helps you.
Have a great day (:
Answer:
The correct answer is option D, that is, bottleneck effect.
Explanation:
A phenomenon, which occurs due to events like earthquakes, floods, or other natural calamities that result in the severe declination in the size of a particular population is known as the bottleneck effect. The bottleneck effect is an extreme illustration of genetic drift that results in the reduction of a population's genetic variability.
With the decline in the size of a specific population, a reduction in the genetic variability of the same population is witnessed due to the loss of alleles. This eventually makes the population vulnerable to pollution and diseases. Hence, the given case is an example of the bottleneck effect.
