How do stem cells relate to the cell cycle?

Biology
1 answer:
kramer2 years ago
6 0

Answer:

Murine, primate and human embryonic stem cells (ESCs) exhibit a very unusual cell cycle structure, characterized by a short G1 phase and a high proportion of cells in the S-phase.

Explanation:

Normally, embryonic stem (ES) cells proliferate quickly during differentiation and do not differentiate simply by cell cycle slowing. In this paper, it is shown that the role of the cell cycle in terminal stages of differentiation can be adapted for and extended into ES cells.

What are molecules and how are they used in running? Evidence
Karolina [17]

Answer:

Osmosis helps cells maintain homeostasis because a cell needs to maintain a specific water balance so that chemical reactions can take place. Osmosis can also be used to balance out the concentration of other molecules (such as sugar or salt) present on either side of a cell membrane.

Explanation:

Homeostasis is the ability of a system to regulate its internal environment through maintaining a stable, relatively constant set of properties such as temperature and PH. Key Terms homeostasis : The ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium, such as the ability of warm-blooded.

Organ where carbohydrate absorption occurs
Rina8888 [55]

Answer: Small intestines

Explanation: Digestion of carbohydrates begins in the mouth mechanically and through salivary amylase. It passes down to the stomach by parastalsis, digested further and goes to the small intestines where their absorption begins. Carbohydrates are a source of glucose, that most organs use as their primary energy source. Indigestible carbohydrates and fibers travels down to the large intestines where they are digested by bacteria or eliminated as waste through the anus.

The small intestines consist of microvilli that increase surface area for maximum nutrient absorption. Carbohydrates are absorbed by the small intestines via the jejunum, taken to the blood stream then transported to the liver where glycolysis and most metabolic pathways take place, for energy production.

2. What is an example of something studied on the molecular level (as opposed to the atomic level)?
Dmitriy789 [7]

Answer:

Something studied on the molecular level is the water.

Explanation:

Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.

The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.

With respect to other options:

  • <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
  • <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>

Enzymes in your gastrointestinal tract digest your lunch. these chemical reactions are categorized as:________
BigorU [14]

Enzymes in your gastrointestinal tract digest your lunch. these chemical reactions are categorized as catabolism.

<h3>What is catabolism?</h3>

The series of metabolic processes known as catabolism reduces molecules into smaller pieces that are then either oxidized to produce energy or utilised in other anabolic processes. Large compounds are divided into smaller components through catabolism.

<h3>What is a prime illustration of catabolism?</h3>

Catabolism happens as you are breaking down food. For instance, a piece of bread is broken down into simple components your body may absorb, such glucose, through this process (blood sugar).

<h3>What is difference between catabolism and anabolism?</h3>

The series of metabolic processes known as catabolism reduces molecules into smaller pieces that are then either oxidized to produce energy or utilised in other anabolic processes. The process of anabolism produces the molecules the body needs to function. Energy is released during the catabolism process. Energy is needed for anabolic processes.
