1. What is the structure labeled
with an arrow?

(The correct option is Nucleus)   instagram pickiloz

Explanation:

The structure in the diagram is a nucleus because the nucleus is a membrane-bound organelle mostly round in shape and it is present inside the cells.

The structure in the diagram cannot be cytoplasm as cytoplasm is a fluid in which organelles float.

The structure in the diagram cannot be a cell wall as a cell wall is the outer layer of a cell and it is not present inside of the cell.

The structure cannot be a flagellum as flagellum are hair-like structures. Hence, option A, C and D are false.

Correct B. Nucleus

Explanation:

Explanation: The arrow points to the nucleus of a mouse skin cell. The nucleus is a membrane-bound structure that contains genetic material. Cytoplasm (light purple) is the gel-like substance inside the cell that surrounds the nucleus. Cell walls are found in plant cells, where they provide protection and support. A flagellum is a whip-like appendage that helps some cells move.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
