The cell uses oxygen in the mitochondria which produces energy, without it the mitochondria makes lactic acid. Lactic acid affects muscles, and causes muscle soreness. That is if the cell is lacking oxygen, if it didn't get oxygen at all i would think that the affects on the body would be more severe.
The question is incomplete as it does not have the options which are:
A. More; more; gravitropism
B. More; less; phototropism
C. Less; more; gravitropism
D. Less; less; phototropism
Answer:
B. More; less; phototropism
Explanation:
Auxin is a hormone which is involved in the plant growth and the development by increasing the flexibility of the cell wall of the plant.
In the given question, the vertical root is rotated to the horizontal orientation which will be sensed by the roots and the roots will then redistribute the auxin in the roots.
The auxin will be transported to the lower areas but the growth of the root in the lower portion will be lowered as a result of which root will grow downward. This is considered a condition called positive gravitropism or negative phototropism.
Since the distribution of auxin is dependent on the presence or absence of light therefore this phenomenon will be referred to as the phototropism.
Thus, Option-B is correct.
The scientist wants to know what type of bases are added to the growing mRNA by the RNA polymerase then it would be bases complementary to the template DNA.
A) 12 is the answer because sex cells have half as many chromosomes as the offspring will have, half from the mother, the other half from the father.
<span>The answer to this question would be: Nonproductive hacking cough
</span>Nonproductive hacking cough is one of the cancer sign even though it's not specific. The cancer cell can stimulate the lung epithelial, causing the patient to cough. Unlike in the infection, the cough is nonproductive and not accompanied by fever. An early diagnosis can help to improve the prognosis of the patient.
