What would happen to the skin cells if mitosis did not take place

1 answer:

5 0

The cells would cease to function after a relatively short amount of time (a few years at best, depending on the amount of cells that part normally has). A living being's body parts would also never grow. They would stay the same size since they were born. The only good result is that without mitosis, cancer wouldn't occur.

According to the Endosymbiotic Theory, infoldings in the cell membrane of an ancestral prokaryotic cell gave rise to endomembran

Ad libitum [116K]

Explanation:

False: C) The ER provides separate microenvironments for each of the modifications that must take place to proteins.

The golgi apparatus comprised of several components called cisternae, these function as different microenvironments, where further modification proteins and lipids into functional biomolecules occurs.

During protein synthesis, transcription occurs in the nucleus, followed by translation within ribosomes, the newly synthesized proteins enter endoplasmic reticulum where they undergo folding and modification. Within the golgi body, the proteins are tagged and parceled into lysosomes for export.

Further Explanation:

The endoplasmic reticulum is a membrane system within the cytoplasm that extends from the outer nuclear membrane. Apart from increasing the surface area within the cell, this continuous system also carries out protein folding, synthesis and transport. In the endoplasmic reticulum or ER, some sections called the smooth ER, do not contain ribosomes, and may contain lipids, enzymes, and other proteins. Other sections bound to ribosomes, are called the rough Er. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen. The proteins undergo major modifications and are packed into vesicles.

Golgi bodies are flat, disk-like membranous regions. Proteins traverse the organelle by first having their vesicles bind to the cis face or receiving end. Like a post office, the golgi complex, or golgi body recognizes specific signal sequences, targets and further modifies and packages these compounds into lysosomes for delivery to their final destination. Proteins here undergo peptide processing and glycosylation

Science is best known for

andreyandreev [35.5K]

Science is best known for logics.

Science is so interesting such that it method of processing and validating logics and facts with verifiable hypothesis and experimental evidence.

This scientific method is also an empirical method of acquiring knowledge which simply involves making observation, establishing hypothesis, designing experiment, analysing result and drawing conclusions.

A hypothesis is a reasonable explanation for a particular observed natural phenomena.

<h3>What is science?</h3>

Science can simply be defined as the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.

So therefore, science is best known for logics
