Research and identify a vestigial structure of an organism of your choosing.
Mariana [72]

Answer:

The one of best example would be appendix in humans.

Explanation:

In the past, the appendix may have helped in the digestion of the plants by producing mucus and prevent any type of infection. Plants with a high content of cellulose are digested with the help of the appendix as reported.

It is not a part of the human digestive system and considers as a vestigial organ. Vestigial organs are the organs that are present in an organism with no particular function and their removal will not lead to any harm. Humans do not need it because our digestive system is more efficient and works better in the first stages of digestion than they used to.

Thus, the correct answer is - appendix in humans.

loris [4]

Answer:

c) pure water on the produce would put it in a hypotonic environment and keep the produce firm.

Explanation:

Ideally, in a natural environment, plants leafs remain fresh and firm looking by absorbing water from their natural environment. However, in a case where these vegetables have been removed from their natural environment, they have lost the ability to absorb water under natural conditions.

In order to keep the leaf cells of the vegetables firm and rigid, so they can look fresh and appealing, they have to be placed in a hypotonic condition i.e. an external condition with high concentration of water. To do this, a grocer in a supermarket will occasionally spray the vegetables with pure water to keep the vegetables' cell from drying out and hence lead to wilting, which would make the vegetables less appealing to customers.
