Answer:
Option-A
Explanation:
RhoA is a protein which belongs to the Rho GTPase family proteins and related Ras superfamily. The Rho A protein is involved in the cell division before the cytokinesis as they are involved in the formation of cytokinesis structures like the actin-myosin rings and the contractile ring formation.
In the given question, if the drug inhibits the activity of RhoA, therefore, cytokinesis will be affected and the cell will complete all the stages of Mitosis except cytokinesis. The cells will be mostly observed in the telophase as cytokinesis will take place after that.
Thus, Option-A is correct.
The answer is C<span>. 3,2,1,</span>
Answer:
Because males are never carriers for x-linked trait, only females are carriers which gives them a lower chance of receiving the trait. While males can either have the trait or not have it.
Answer: Option B
Explanation:
Deforestation can be defined as the cutting down of trees in huge number. This act increases the amount of green house gases in the environment.
This is so because the carbon dioxide which is an important green house gas is absorbed by the trees which reduces the concentration of green house gas and thus decreases green house effect.
But lesser number of plants will increase the amount of carbon dioxide in the atmosphere thus increasing the green house effect.
Answer: a.myoglobin
Explanation:
Myoglobin (Mb) and Hemoglobin (Hb) are heme proteins and are part of the family of globular proteins. These proteins are characterized by having the spherical or globular wrapped polypeptide chain having various types of secondary structures. Myoglobin is an extremely compact protein found in muscular cells of vertebrate animals, having as their main function the storage and it also facilitates the transport of oxygen in the muscles. This protein is found in the cardiac muscle and skeletal muscle of the mammals and increases the effective solubility of oxygen in the muscle by acting as an oxygen reservoir and facilitating the diffusion of O2 from the capillaries blood to the mitochondria.
