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.Learn more at: https://brainly.com/question/20285092?referrer=searchResults
what are four examples of nutrients cycled in a biogeochemical cycle
Answer:
The Gaseous cycles include those of nitrogen, oxygen, carbon, and water; while the sedimentary cycles include those of iron, calcium, phosphorus, sulfur, and other more-earthbound elements.
Explanation:
Major examples are carbon, phosphorus, nitrogen, and oxygen in nutrient cycles in the biogeochemical cycle.
What are important nutrients in the biogeochemical cycle?Most of the elements are important to flow in the ecosystem to obtain living things and their surrounding environment in a balanced state.
This cyclic flow provides energy at every level in the ecosystem, carbon is an important substance synthesis during the photosynthesis process and this plays role in energy molecule flow in a particular direction.
In the biogeochemical cycle carbon cycle, oxygen cycle, nitrogen, and phosphorus cycle flow between the living organism and nonliving matter.
Therefore nitrogen, phosphorus, oxygen, and carbon are major nutrients in a biogeochemical cycle.

what is the main function of the reticular activating system?
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

what is the approximate percentage of total fixed nitrogen attributed to human activities?
Of the annual global total of fixed nitrogen, human activities account for roughly 45%.
Nitrogen fixation is the global amount of nitrogen that gets assimilated by any living organism into another organic compound. The organic compound can be ammonia or nitrogen ions.
Of the total global annual nitrogen fixation, humans account for a great amount. The current estimation is that humans cause 45% of the nitrogen fixation annually. The leading causes of this high rate are the burning of fossil fuels and increased agricultural fertilizer use.

Where in your body do you think cell division is occurring?
Answer:
Everywhere except in gonad cellsExplanation:
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.

and no membrane bound organelles, as mitochondria and chloroplasts,
then it is classified as *
A.Eukaryote
B.Prokaryote
C.Endosymbiosis
D.both a and b
Answer:
B. Prokaryote
Explanation:
Because it does not have a well defined nucleus and bound organelles
Answer:
B
Explanation:
A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle.In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. ... Throughout the course of evolution, organelles such as mitochondria and chloroplasts (a form of plastid) may have arisen from engulfed prokaryotes.
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.
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.
