It is mostly likely the cell membrane.

The cell membrane is a structure of a cell composed of double layer of lipids and proteins. It surrounds a cell and separates the cytoplasm from its surrounding environment. The cell membrane is selectively permeable (semi-permeable), which means that it only lets certain molecules enter and exit. It can also control the amount of some substances that go into or out of the cell.

polet [3.4K]
During telophase in mitosis or meiosis II, where chromosomes which were previously distinct and condensed, de-condense and spread out into a tangle of chromatin. At the same time, the nuclear envelope re-forms around each cluster of chromosomes in each of the daughter cells, and spindle fibres disintegrate.

Chromosomes are unlikely to de-condense and spread out into a tangle of chromatin during telophase I (i.e. Telophase of Meiosis I), since Meiosis is still ongoing, and the genetic material should be in its condensed form during Meiosis II as well. 

Hope this helps! :)

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>
