- Force exerted by the table.
<h3>What is Force?</h3>
This is described as an influence which changes the motion of an object. The force exerted before motion is that which is exerted by the table , drag and force of gravity.
During fall, all other forces act except that exerted by the table thereby making it the most appropriate choice.

Answer:
Stomata opens to intake carbon dioxide in the presence of light there by allowing the process of photosynthesis during the day time.
Explanation:
The gaurd cell of the stomata play an important role in regulating the photosynthesis. During the day time, the stomata is open which allows intake of carbon dioxide from atmosphere. Carbon dioxide is very essential for the process of photosynthesis. Thus, during day time when stomata is open photosynthesis takes place while during night time when stomata is closed photosynthesis do not occur. Also the stomata regulate the loss of water from the leaves thereby ensuring availability of sufficient water molecules at the time of photosynthesis.
The answer is false.
The group of similar cells working together to perform a specific job is called a tissue. The functional group of multiple tissues is called organ. Functionally related organs form organ systems, which all together form one organism.
So, surgeon is working at the organ level. The lungs are the organs of transpiration. Since they are organs, they consist of multiple tissues, which consist of many cells. But the surgeon does not work on one single cell, he works with the whole organ.
Answer:
B. The frequencies of alleles in this new dodo population may be very different from the frequencies from 1,000 years ago.
Due to a population bottleneck, the frequency of alleles in this new dodo population may be very different from the frequencies expected in larger (now nonexistent) populations
