Through a division process called mitosis, eukaryotic cells divide to create new cells. It enables cell replacement after damage or wear-and-tear and also permits growth.
Mitosis is the process of cell division in which the chromosomes replicate and are evenly dispersed into the two daughter cells. It specifically refers to the division of the duplicated genetic material held in the nucleus during cell division. Each daughter cell has the same number of chromosomes as the parent cell, making them diploid. So, meiosis is the process where a single cell divides twice to produce four cells with half the original amount of genetic material. Mitosis is known as equational division. These cells are our sex cells, producing sperm in males and eggs in females throughout the process of mitosis. Eukaryotic cells go through the nuclear division process known as mitosis when they divide to produce two identical daughter cells.

Answer:
A. Blood would leak backwards through the damaged valves due to gravity, causing lower leg swelling.
Explanation:
The passage of blood is always in a single direction in the vein due to the presence of valves in the veins.
Any kind of vein injury or vein rupture, causes the valves in the veins to not function in an appropriate manner. The injury might result in inappropriate opening and closing of these valves. The inappropriate functioning of the valves causes the blood to flow backwards. This will eventually lead to blood pooling and putting more pressure on the lower leg veins. hence, there would be swelling in the lower legs.
Hello. Your question is incomplete. However, when researching, I managed to find a question like yours and found that you forgot to mention that the question wants you to determine which is the best reference point in this scenario.
Answer:
The best point of reference is the starting position of the toy car.
Explanation:
To study the movement of the car it is necessary for Sudhi to establish a reference point, so that she can calculate all the variables associated with this movement. The best variable in this scenario is the starting position of the car, when it is still on the ramp. Thus, Sudhi needs to determine the distance between the car and the ground, that is, what the car's starting position is. She will be able to discover this when determining the height of the ramp.
The appropriate response is Nitrogenous Base. It is just a nitrogen containing atom that has an indistinguishable concoction properties from a base. They are especially vital since they make up the building pieces of DNA and RNA: adenine, guanine, cytosine, thymine and uracil.
