When a cell is deprived of oxygen, its lysosomes tend to burst and release their contents into the cell. As a result of this, th
Nikolay [14]

Answer:

The correct answer is - undergo self-digestion and die.

Explanation:

Lysosomes are cell organelle that is membrane-bound and has digestive enzymes in them. These cell organelle help in digesting cells that are worn out, ruptured cells deprived of oxygen by bursting themselves.

Its bursting nature also helps in digesting and killing antigens and microbes. It is a very essential cell organelle that helps in digesting and killing damage cell parts or cells.

The cell cycle of yeast cells grown in the nutrient-poor environment is approximately what percent of the cell cycle of yeast ce
vova2212 [387]

Answer:

Upon nutrient limitation, budding yeast will produce daughter cells less than 20% of the mother cell size. This asymmetric division may select for growth functions that are efficient over a larger range in cell sizes, such as exponential growth. In turn, efficient growth over a large size range lessens the pressure to have precise size control.

Explanation:

In wild-type cells growing in nitrogen-rich medium, the size threshold to enter mitosis is high, and the G1/S size control is cryptic because cell division produces daughter cells with a size greater than the minimum required to initiate S phase. In these conditions, G2 is long and G1 is short. However, the cell size threshold to enter mitosis is greatly reduced when wild-type cells are shifted to medium with a poor nitrogen source, such as minimal medium with proline, isoleucine, or phenylalanine. In these conditions, wild-type cells initiate mitosis at a reduced cell size, generating two daughter cells that are smaller than the critical size threshold required to progress through G1/S

9. In guinea pigs, rough coat is dominant (R) to smooth coat (r) and black coat (B) is dominant to white coat (b). A rough black
lisabon 2012 [21]

Answer:

the genotype of the parent guinea pigs are as follows:

RrBb (rough, black) and Rrbb (rough, white)

Explanation:

Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.

After making the dihybdrid cross, the probability obtained for each phenotype is given below:

rough black: \frac{3}{8}

rough white: \frac{3}{8}

smooth black: \frac{1}{8}

smooth white: \frac{1}{8}

Hope that answers the question, have a great day!
