<h2>c) is the correct option</h2>
Explanation:
Inhibition of Cdk activity occurs by Cdk inhibitory protein (CIPs)
- A group of specific proteins called CIPs binds with active cyclin Cdk complex and cause their inactivation
- Activated protein retinoblastoma (p53)act as transcriptional factor and induce synthesis of Cdk inhibitory proteins p21CIPs
- p21CIPs is a Cdk inhibitory protein that binds and inhibit the activity of G1 Cdk cyclin complex as a result cell cycle arrest in G1 phase
Answer:
(2) diffusion
Explanation:
Diffusion is a process in which molecules moves from a region of higher concentration to the region of lower concentration. In this condition, plant roots contain high concentration of nitrates than soil so nitrates moves from roots through semi-permeable to the soil by the action of diffusion until the concentration is uniform or equilibrium.
The right answer is a colored square (or shaded).

It is a dominant trait, it means that the heterozygotes will express the trait.
