The changes in the grape juice happened due to the alcoholic fermentation of the grape juice that occurs due to the presence of aerobic bacteria. The presence of yeast is the main reason behind the process of fermentation taking place. The froth is produced due to the presence of the formation of acid and carbon dioxide.

Would a bacterial cell undergo mitosis in the same way as a eukaryotic cell? Why or why not?
nikklg [1K]
Unlike eukaryotes, prokaryotes (which include bacteria) undergo a type of cell division known as binary fission. In some respects, this process is similar to mitosis; it requires replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm.

Skeletal muscle cells exhibit a phenomenon known as recruitment, in which the number of muscle cells recruited to contract is pr
Sergio039 [100]

Answer:

No, cardiac muscle tissue does not exhibit recruitment.

Explanation:

The cardiac muscle tissue does not recruit cells to contract. The reason is that the cardiac muscle contracts all its cells at once and with the same force. It does not have to recruit other cells since it does not have to lift objects of different weights. The heart's contraction aims to pump blood and to do it rhythmically. The heart has a natural peacemaker, the sinoatrial node. The Sinoatrial node transmits an electrical impulse to all the heart to contract it all at the same time and continuously. For these reasons, the cardiac muscle does not need recruitment.
