The correct answer is option C, the concentration of the hydroxide ion is greater than the concentration of the hydronium ion
Reason -
An acidic solution has an ability to contribute hydrogen ion. Here a hydronium ion (H3O+) has an extra H+ ion along with a water molecule. Thus presence of hydronium ion in larger amount than the hydroxide ion would make the solution acidic. Thus, the concentration of hydroxide ion should be less than the hydronium ion to make the solution a basic solution.
Correct answer: B). Cell growth
The Interphase is often referred to as a metabolic phase of the cell cycle because in this phase the cell obtains nutrients, read its DNA, conduct other cell functions. Most of the eukaryotic cell spend most of their time in interphase, it is also called as a resting phase.
The main purpose of interphase is to prepare and check the conditions in order to conduct the successful cell division. In this phase, the cell prepares itself for the division. In this phase, the cell organelles double in number and replication of DNA takes place, and the synthesis of protein, which is required for cell growth are made in this phase of cell growth.
Answer:
The correct answer will be option-E.
Explanation:
Chordae tendinae are the string-like structure in the heart which is composed of dense regular connective tissue called collagen and elastin proteins. They arise from the papillary muscles of the heart and branches out in the ventricle portion of the heart.
These play an important role in the closure of the AV valves to prevent the backward flow of the blood to the atria during ventricular contraction by holding cusps of the valve into the dome-shaped structure.
Thus, option-E is the correct answer.
