Answer:
Changes in gene expression
Explanation:
This phenomenon is the result of changes in gene expression. That means, how the information in the DNA is used by the cell. The genes that are active in the cells of the brain will be very different from the genes that are active in the cells of the bone marrow.
These patterns of gene expression are different for each cell, and dictate the identity of that cell. Gene expression patterns are controlled by a variety of factors in the cell that allow tissue-specific expression, such a transcription factors.
This can also be facilitated by another layer of regulation called epigenetics, which literally means "on top of" genetics, and refers to modifications of DNA (and the proteins around it), that can reflect and influence the activity of the genes within.
Answer: Daughter cell that does not receive mitochondria, will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria, will be able to carry out cellular respiration and thus produce energy.
Explanation:
The mitochondrion is a cellular organelle found in eukaryotic cells, and provides the energy needed to carry out cellular activity. They are characterized by their large size, compared to other cell organelles, and their globular shape. <u>Mitochondria generate most of the chemical energy needed to activate the biochemical reactions in the cell</u>,<u> through a process called cellular respiration</u>. It irefers to a set of biochemical reactions by which certain organic compounds are degraded by oxidation into inorganic substances. The chemical energy produced by mitochondria is stored in an energized molecule called adenosine triphosphate (ATP).
Then, if during cell division, one of the daughter cells does not receive mitochondria, it will not have the necessary organelles to carry out cell respiration and will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria will have no major problems, it will be able to carry out cellular respiration and thus produce energy.
In contrast to the stratified squamous epithelium of the skin, the intestinal barrier is composed of a single layer of columnar epithelial cells However, this single layer of intestinal epithelial cells is made of diverse cell types with absorptive, secretory, and immune function
