Why do all normal cells in human body have same number of chromosomes?

Answers

Answer 1

Answer: The reason as to why all human body cells have the same number of chromosomes is because of the process of mitosis and meiosis.

Mitosis is the process of cell division in which body cells or somatic cells divide to yield two daughter cells with the same number of chromosomes as the parent cells. The process involves a series of steps, and results in the formation of two new nuclei each having the same number of chromosomes as the parent nucleus. The process ensures that have the same number of chromosome. In meiosis, sex cells have half the amount of chromosomes that a normal cells has and therefore when they join another, there are 46 chromosomes in the cell.

Answer 2

Answer: Females have two X chromosomes in their cells, while males have one X and one Y chromosome. Mitosis; before it divides it replicates & meiosis; sex cells have half the amount of chromosomes that a normal cell has so when they join another, there are 46 chromosomes in the cell.

Consider this animal cell.The organelles in an animal cell are labeled. Part A is a structure that is comprised of flattened membranous sacs.

Which organelle is labeled A?
mitochondrion
ribosome
Golgi apparatus
lysosome

Answers

Answer:

The answer to your question is the Golgi apparatus

Explanation:

Mitochondria is letter G

Ribosome could be letter E

Golgi apparatus is letter A

Lysosome is letter B

Golgi apparatus has a function similar to a post office because it modified, sorted, packed and distributed proteins and lipids.

Final answer:

The organelle labeled A in an animal cell is the Golgi apparatus. It plays a role in altering, organizing, and preparing proteins and lipids for various cellular functions.

Explanation:

The Golgi apparatus is commonly known as the Golgi complex and is composed of flattened membrane sacs known as cisternae. It is involved in modifying, sorting, and packaging proteins and lipids that are synthesized in the endoplasmic reticulum (ER) and preparing them for transport to their final destinations. This organelle is essential for cell maintenance and function, having a major role in processing molecules created in the endoplasmic reticulum and preparing them for their specific uses, either within the cell or to be sent out of the cell.

Endorphins increase basal metabolic rate. increase muscle mass. reduce appetite. reduce carbohydrate cravings.

Answers

The answer is "Endorphins reduce appetite." Endorphins are hormones that are released when you exercise. They have several benefits such as decreasing appetite, reducing stress, blocking pain, and simulating euphoria. The more exercise you do, the more endorphins you release. This means that more endorphins stay in your blood which makes it easier to do longer periods of exercise.

Bone marrow produces _____________
Enzymes
Insulin
Red and White blood cells

Answers

Red and White blood cells:

These are produced by the stem cells in the bone marrow. There are two types of stem cells for producing white blood cells - Myeloid stem cells (producing phagocytes such as neutrophils and monocytes - the undeveloped version of macrophages) and Lymphoid stem cells (responsible for production of lymphocytes such as B and T cells).
