The answer is; D


These cells are called plasmodesmata. They are significant in the symplastic flow (meaning through the cytoplasm) of water and other molecules in the plant. A membrane called desmotubule runs along the pores of adjacent plasmodesmata. These cells are also significant in the communication between cells.

A botanist has discovered a new plant species and is trying to classify the plant. Its seed has one cotyledon, it has six flower
lana66690 [7]

The best suited group for the mentioned plant is Angiosperms and monocot.

Answer: Option C

<u>Explanation:</u>

As mentioned the seed of the plant has one cotyledon and the specific name for these type of plants whose seeds has one cotyledon is called Monocot, Suppose if the seed of the plant has two seeds, It is called dicot.

Hence we can conclude that the mentioned plant comes under monocot and not dicot.  On the other hand, Angiosperms refers to the plants that has flowers with it and gymnosperms usually includes plants without flowers and hence we can classify the plant as Angiosperm and monocot.

OPTIONS:

a. When there are just two other people at the party.

b. When everyone is wearing a nametag.

c. When there are more than 50 people attending the same party.

d. When the need for help from the person who is having a heart attack is very clear

Answer:

c. When there are more than 50 people attending the same party.

Explanation:

Bystander effect is a term used in social psychology to describe the tendency of an individual to intervene in the event of an emergency to offer help to the person needing it, when others are present at the scene of the emergency.

In the case of an emergency just like the scenario stated in the question, where someone develops a heart attack at a dance party, if the party has more people, the slimmer the chance of the person getting help from any of the 50 people at the party, as the presence of others would tend to discourage the any individual from attempting to help the victim having the heart attack.

The situation that would more likely show the bystander intervention effect is <em>"c. When there are more than 50 people attending the same party."</em>

The large central vacuole would become dehydrated, because without enough water stored in it, there wouldn't be any turgor pressure (water pushing against the cell wall) to support the cell, which causes the plant to wilt.
