Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Answer: proteins
Explanation: Ribosomes are the protein builders or the protein synthesizers of the cell.
Answer:
If the calcium levels in blood increases, then there is increase in blood glucose level.
Explanation:
Calcium in blood plays a vital role of homeostasis in regards to level of secretion of insulin. If the calcium level is altered, the homeostasis mechanism is hampered. Several researches have shown that alteration of serum calcium level affects the metabolism process of carbohydrate and makes the person vulnerable to risks of diabetes mellitus and associated complications. Hence during calcium supplementation, the person's blood glucose level must be considered.

Answer:</h2>
Option B.
<h2>
Explanation:</h2>
- <u>Phototropism</u> is the process in which plant grow in response to light. Where "Photo'' means light and ''Tropisms'' are responses to external stimuli in this case stimuli against light.
Now, going back to the question
- Plant cells grows faster in the presence of the hormone auxin.
- As a result when a plant senses a light from a direction, auxin molecules accumulates to the side that is further away from the light, due to which the plant cells that are further away from the light experience a greater auxin concentration and grow faster, due to which shoot gets bend towards the direction of the applied light.
- <u>Gravitropism</u> is a process of growth by a plant in response to gravity pulling on it. Roots show positive gravitropism i.e they will grow with the gravitational pull and stems show negative gravitropism that is they will grow against gravitational pull.
- Auxin is a plant hormone which promotes stem elongation and inhibits the growth of lateral buds.
- Auxin helps in maintaining apical dominance, which means in presence of auxin the plant will grow Vertically upward i.e against the gravity. Hence Auxin promotes gravitropism.
Result: Phototropism and Gravitropism is controlled by Hormones
The Correct Answer is A: Glycolysis
Explanation:
In glycolysis, the beginning process of all types of cellular respiration, two molecules of ATP are used to attach 2 phosphate groups to a glucose molecule, which is broken down into 2 separate 3-carbon PGAL molecules. PGAL releases electrons and hydrogen ions to the electron carrier molecule NADP+.
