Answer:
centromere.
explanation:
the contromere is the structure that joins the two chromatids to make a chromosome.
- The nucleus is responsible for housing the nucleolus, storing DNA, and housing chromosomes. Digesting bacteria is the responsibility of a different organelle.
So the answer would be digesting bacteria.
- Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.
Answer: B. In hypoxic tissues, in contrast to normoxic tissues, ATP is additionally consumed to transform lactate to pyruvate
Explanation:
In hypoxic tissues such as new cancerous cells, the vascular system is still underdeveloped, thus oxygen supply is reduced. To meet energy need, additional glucose is needed to convert lactate (result of anaerobic glycolysis) to pyruvate which can then go into the TCA cycle to yield energy. This phenomenon is very common in muscle tissues during exercise.
