The process of differentiation is the process by which cells become specialized.

CELL DIFFERENTIATION:

Cell differentiation is the process by which an unspecialized cell becomes specialized in function.

Cell differentiation is undergone by stem cells, which are regarded as totipotent cells. The process of cell differentiation occurs as a result gene expression.

Cells like heart cells, blood cells, liver cells, kidney cells etc. are examples of specialized cells.

Therefore, the process of differentiation is the process by which cells become specialized.

Where in your body do you think cell division is occurring?

Answers

Answer:

Everywhere except in gonad cells

Explanation:

Cell division by mitosis occurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46. In the sex cells, meiosis occurs where the DNA is halved and the daughter cell has only 23 chromosomes.

what is the main function of the reticular activating system?

Answers

The reticular activating system's main function is regulating arousal and sleep−wake transitions

The reticular activating system's main function is regulating transition between arousal and sleep−wakeness.

what is reticular activating system?

The reticular activating system (RAS) is a bundle of nerves located in the brain and  it is responsible for regulating wakefulness and sleep-wake transitions.

 It  is also involve in filtration of noise with processing of messages or make it slower during  sleep, it alters the  brain's electrical activity,  electrical voltage of brain waves and the speed.

The primary function of RAS is higher at brain centres when important messages are received and filter the important messages, for example The eye sends messages to the brain through the optic nerve.

If the RAS system is damaged, it can cause sleep problems, lethargy, or coma, also play a role in narcolepsy and degenerative brain disorders like Parkinson's disease and supranuclear palsy

Which of the following statements are FALSE? A. Meiosis separates homologous chromosomes in a diploid cell to produce haploid daughter cells containing one copy of each type of chromosome. B. During prophase I, homologous chromosomes pair up and exchange DNA. C. During meiosis II, paired homologous chromosomes move up to the equator of the cell. D. During anaphase I, homologous chromosomes separate. E. In meiosis II, the sister chromatids of each chromosome separate. F. In meiosis I, ploidy is reduced. G. In meiosis II, ploidy is reduced. H. During anaphase I, sister chromatids separate.

Answers

The statements about meiosis that are false include the following:

C. During meiosis II, paired homologous chromosomes move up to the equator of the cell.

G. In meiosis II, ploidy is reduced.

H. During anaphase I, sister chromatids separate.

Meiosis can be defined as a type of cell division or duplication that occurs in all body cells found in living organisms, through which a single cell divides twice to produce four (4) haploid cells (gamete).

During cell division, deoxyribonucleic acid (DNA) must be replicated before meiosis can take place in any body cell found in living organisms.

Generally, the phases or steps that occur during meiosis include:

Prophase I.Metaphase I.Anaphase I.Telophase I.Prophase II.Metaphase II.Anaphase II.Telophase II.

Furthermore, the statements about meiosis that are false include the following:

1. During meiosis II, paired homologous chromosomes move up to the equator of the cell.

The movement of paired homologous chromosomes to the equator of the cell takes place during prophase II.

2. In meiosis II, ploidy is reduced.

Actually, it is meiosis I that reduces ploidy.

3. During anaphase I, sister chromatids separate.

Sister chromatids are separated during anaphase II.
