Answer:
Chromosomes would divide in interphase and enter mitosis. However, the spindle apparatus would not form, so the chromosomes would end up in the metaphase form and no further mitotic events would take place.
Explanation:
<span> RNA was thought of as little more than a messenger between DNA and proteins, carrying instructions as messenger RNA (mRNA) to build proteins. However, RNA can do far more. It can drive chemical reactions, like proteins, and carries genetic information, like DNA. And because RNA can do both these jobs, most scientists think life as we know it began in an RNA world, without DNA and proteins.</span>
Answer:
True.
Explanation:
White blood cells cannot function properly and their reduced production can lead to fever and frequent infections. This is because the function of white blood cells in fighting germs has been disrupted.

- The glands are swollen. If the glands in the neck and chest are swollen, it can cause blood flow to be blocked. This causes the face to swell, difficulty breathing and snoring.

Answer: a. begins to accumulate significantly at a point that is about 55-65% of Vo2 max
Explanation:
Lactate is produced in the body after the burning of glucose (glycolysis), to supply energy without the presence of oxygen (lactic anaerobic metabolism). In long-term physical activities, oxygen supply is not always sufficient. The organism seeks this energy in alternative sources, producing lactate. For the average human, blood lactate begins to accumulate significantly at a point that is about 55-65% of Vo2 max. The accumulation of this substance in the muscles can generate a hyperacidity, which causes pain and discomfort soon after exercise. Thus, the determination of lactate blood concentration allows indirect evaluation of the metabolic acidosis of the exercise, being one of the diagnostic tools used by Exercise Physiology.
