These are grape-like clusters surrounded by <u>blood capillaries</u>

Explanation:

The alveoli (grape-like structures) are surrounded by a network of blood capillaries. They supply blood for decarbonization and oxygenation. The large network provides a large surface area for this gaseous exchange. In addition, the alveoli are moist to help increase the rate of diffusion of the gases in and out of the blood capillaries.

Whitepunk [10]

Answer:

The parent cell is also making a copy of its DNA to share equally between the two daughter cells. The mitosis division process has several steps or phases of the cell cycle—interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis—to successfully make the new diploid cells. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
