A. Genes involved in the cell cycle
This is because cancer is a defect that causes the cell to repeatedly divide and undergo mitosis. If genes involved in the cell cycle mutate, the genes that limit and regulate the cell cycle may be changed or inactive, leading cancer cells.
Answer:
Starvation
Explanation:
Hormones like Insulin, which are anabolic are low during starvation. While Glucagon and epinephrine are high which promote catabolism.
Answer:
Option-B
Explanation:
Phototropism refers to the movement of plants in response to light. The mechanism of phototropism involves the photoreceptors which respond to a different wavelength of light: the phytochromes to red light, cryptochromes to blue light and the phototropin to the UV light.
Plants integrate the signals obtained from these receptors and then activates the gene which will be involved in the phototropism.
The gene could be the production of the auxin hormone and the PIN proteins which helps in the distribution of the auxin in the plants. Due to the production of this hormone and its distribution in the shoot, the grass tips bend towards the light.
Thus, Option-A is correct.
