Stomata are pores in the epidermis of a plants leaf that allow for the expulsion of gas, and are protected by two curved guard cells. If the environment around the plant is hot and dry the guard cells will shrink and cause the stomata to close to conserve excess water, when there is a large amount of moisture the guard cells will absorb the water and become turgid. And the stoma are found on the underside of the leaf to minimize water loss

A number of mutations have been described in the G protein Ras that have profound effects on its activity. For example, some mut
gladu [14]

Answer:

a mutation that blocks the GTPase activity of Ras

Explanation:

A G protein in inactive state is GDP bound but as soon as a guanine exchange factor (GEF) exchanges it with GTP it gets activated which means that in GTP bound state it is active. G - protein has endogenous GTPase activity. Upon interaction of GAP, the GTPase activity of this protein is exhibited. When GAP is present, hydrolysis of GTP into GDP occurs which leads to inactivation of G protein. A mutation which will block GTPase activity of Ras will therefore result in constitutive active signaling even in the absence of ligand binding to it's receptor. In such scenario, GTP will not be hydrolyzed into GDP so signaling will be up-regulated.

Arturiano [62]

The right option is; D) mitosis

In multicellular organisms, life begins as a single cell until mitosis occurs, causing growth.

Mitosis is a process of cell division, and a part of the cell cycle in which a single cell divides, and produces two identical daughter cells (new nuclei) that contains the same shares of the parent’s cell part. Mitosis occurs in multi cellular organisms, and its primary purpose is for growth, and to replace worn out cells. Mitosis contains four basic stages which are; prophase, metaphase, anaphase, and telophase.
