How many chromosomes would be present in a cell after anaphase of Mitosis?
During anaphase, sister chromatids separate to opposite sides of the cell. Therefore the 4n after doubling returns to 2n at each end of the dividing cell after anaphase. But until cytokinesis (1 cell pinching into 2), it's still one cell therefore 4n = 28
A way of storing carbon in organic material is Burning fossil fuels or D all of these
Hi
The answer is called a mutation
The substances that protect against oxidative stress and the resultant tissue damage at the cellular level is, option B. Antioxidants. Oxidation can cause imbalance in the body. Antioxidants are used to counteract the damage produced by free radicals. Good natural sources of antioxidants include fruits and vegetables.
Answer:
Explanation:
The complete question is as follows :
Animals that maintain internal body temperature using heat generated by their own metabolism are called:
A)thermoregulators.
B)hibernators.
C)aerophiles.
D)endotherms.
E)dormants.
- An animal that is capable of maintaining a body temperature that is metabolically favorable for the organism is known as an endotherm.
- The body temperature is maintained by an endotherm by using its internal body capacity to generate heat rather than depending on the ambient temperature.
- Some of the mechanisms used by endotherms to maintain a suitable internal body temperature include shivering, uncouple oxidative phosphorylation, sweating, flushing, etc.
- The endotherms include birds and mammals.
- The ability to perform endothermy is owed to the presence of a large number of mitochondria that enables the organism to increase the rate of metabolism to generate heat as and when required.
