I think it’s false but jsjs
<span>Poisson's ratio (ν), named after Siméon Poisson, is the ratio, when a sample object is stretched, of the contraction or transverse strain (perpendicular to the applied load), to the extension or axial strain (in the direction of the applied load).

Cardiac systole is the contraction of the cardiac muscle in response to an electrochemical stimulus to the heart's cells (cardiomyocytes<span>).

Mitosis is the process of cell division that creates a new cell identical to the original. Somatic cells, such as muscles, hair and skin, undergo mitosis regularly in humans and other organisms. This is an important type of cell division needed to facilitate the repair of damaged cells, growth and replacement of old cells with new ones.
When a new cell is created, it must have the same library of genetic information all other cells in the body have access to. Because all the material in the new cell must come from the first cell, the original cell must make a copy of its DNA before completing the process of mitosis. These two sets of DNA only exist for as long as it takes the cell to undergo mitosis, which can be anywhere from 30 to 90 minutes in certain human cells. When the cell division is complete, both of the cells have a single identical copy of DNA.
Answer:
The correct answer will be option-A.
Explanation:
The females carry two X-chromosomes in their cells but one of these X-chromosome gets permanently inactivated during embryonic development.
The X-inactivation is known as lyonization which ensures that only one functional X-chromosome should be present like in males. This process is a random process and therefore a female can have both the functional X-chromosomes and males can also have a functional X-chromosome.
Thus, option-A is the correct answer.
