how can injury to tissue prompt cells in the surrounding area to undergo cell division?

Answers

Answer 1

Cell division is the process essential for growth and repair in multi-cellular organisms.

Injury to the tissue can activate surrounding cells to undergo cell division with the help of mitogens. Mitogens are the chemical substances which help in escalating mitotic divisions in the cells.

They act by activating the signal-transduction pathway which involve mitogen-activated protein kinase (MAPK).

Other possible manner could be the loss of density which could lead to the inactivation of contact inhibition. As there is a loss of cells during the injury, it makes an empty space which could also trigger or activate surrounding cell to start cell division.

In addition, at injury site the flow of blood also increases to transport various nutrients, clotting factors, growth factors etc. These increased nutrition and growth factors also speed up the process of mitosis.

Answer 2
Final answer:

Injury to tissue triggers cell division through inflammation and the release of chemical signals and growth factors, which signal surrounding cells to replicate and repair the damage. External events, such as injury and hormone levels, regulate the repair process by promoting the necessary cell division. Fibroblasts and stem cells are essential players in regenerating damaged tissue.

Explanation:

Injury to tissue can prompt cells in the surrounding area to undergo cell division through a process that involves signaling from damaged cells, inflammatory responses, and the action of growth factors. When tissue is injured, resident cells such as mast cells and macrophages release chemical signals that can lead to inflammation, resulting in redness, warmth, swelling, and pain. This inflammation is part of the body's natural healing process. During the repair phase, cells like fibroblasts are critical as they deposit collagen and aid in tissue regeneration. Additionally, external events can regulate cell division. For example, the death of nearby cells or the release of growth-promoting hormones like human growth hormone (HGH) can kickstart the process. Blood capillaries and immune cells help increase circulation and fend off infection, further supporting the healing process. To adequately replace lost or damaged tissue, the stem cells within it must divide to form new cells.

On the molecular level, cell signaling pathways are instrumental in prompting cell division. Cells typically don't divide unless stimulated by signals, often in the form of growth factors binding to cell-surface receptors. These growth factors provide the needed prompts for cells to begin the process of division and replication to repair damaged tissue.

Lastly, cell division is necessary for wound repair. If the surface area that needs repair is extensive, basal stem cells and fibroblasts divide rapidly to recreate the skin and supporting structures. Burn treatment often involves aiding this process through fluid and nutrient support to enable the body's cells to divide and repair tissue.

Answers

I think it’s c but not sure

Carbon dioxide diffuses from the atmosphere to the ocean, where it reacts to form carbonic acid. The correct option is C.

What is ocean acidification?

Ocean acidification is the term used to describe a long-term drop in the pH of the ocean that is mostly due to the ocean's absorption of atmospheric carbon dioxide.

The vast amount of carbon dioxide that the ocean is absorbing dissolves as carbonic acid in saltwater.

Ocean acidification is a process that is literally changing the sea and endangering the basic chemical equilibrium of ocean and coastal waters from pole to pole.

Global warming is being caused by an increase in greenhouse gases, primarily owing to human activity. Global warming is a result of deforestation and an increase in air, water, and land pollution.

From the atmosphere, carbon dioxide diffuses to the ocean, where it reacts to produce carbonic acid.

Thus, the correct option is C.

If the yellow allele is dominant (Y) and the green allele is recessive (y), what are the possible genotypes of a yellow offspring

Answers

The possible genotypes are YY or Yy.

Since the yellow allele is dominant over the green allele, whenever the yellow allele is present in the genotype, the offspring will show yellow phenotype. Doesn’t matter whether the green allele is present or not. Only if both allele are green will make the offspring green.

Therefore, both YY and Yy genotypes will produce a yellow offspring.

Wild salmon spend most of their lives in the ocean but return to freshwater rivers to spawn, or reproduce. Most wild salmon will only spawn in specific spawning grounds in the rivers in which they were born. The construction of hydroelectric dams in rivers has blocked the paths of some salmon returning to their spawning grounds. This has led to population declines. Which method would be most effective in preventing further wild salmon population declines caused by the construction of hydroelectric dams?
A.
constructing passageways next to dams to allow salmon to swim around blocked rivers
B.

C.
observing the migration patterns of wild salmon by tagging and tracking a small sample of fish
D.

Answers

Answer: A

Constructing passage ways near the dams to allow to salmon to swim around blocked rivers.

The construction of dams in rivers has blocked the path of  some salmons returning to spawning grounds. The best way to overcome this is to make the passage ways near the dams to allow salmons to swim in areas which have blocked due to dams. So that salmons can returned to the spawning ground and can spawn which leads to increase in their population.

Answer and Explanation:

Answer: A

Constructing passage ways near the dams to allow to salmon to swim around blocked rivers.

The development of dams in streams has hindered the way of certain salmons getting back to bringing forth grounds. The most ideal approach to defeat this is to make the entry ways close to the dams to permit salmons to swim in regions which have impeded because of dams. So salmons can got back to the producing ground and can generate which prompts increment in their populace.

Answer:

C: structures found in single- celled organism can act in a manner similar to tissue and organs in multi-cellular organisms

Explanation:

The question above shows a certain similarity in the function of structures of unicellular and multicellular organisms. As we can see, vacuoles are indispensable in balancing water within single-celled organisms. This function is similar to the function of the kidneys, in multicellular organisms, which is also responsible for the balance of water.

In addition, the function of the kidneys is, among others, to filter the blood to eliminate substances harmful to the body, such as ammonia, urea and uric acid. They also work to secrete substances important to our health. The kidneys receive blood from the renal arteries, branches of the aorta that come directly from the heart.

Jack is learning to play the piano he knows that a piano has 88 keys and that there are 12 unique keys in each group called an octave how many complete octaves are on a piano

show work


math

Answers

All you would have to do for this is divide 12 by 88. So, 88/12 is 7.333333. That isn't a full number, which is probably what is confusing you. Although, since the question is asking for how many COMPLETE octaves on a piano, it would be 7 because there are 7 complete octaves, and a little more.

By dividing the total number of piano keys (88) by the number of keys in an octave (12), we find that a piano has 7 complete octaves.

To calculate the number of complete octaves on a piano with 88 keys, where each octave consists of 12 unique keys, we can perform a simple division operation. By dividing the total number of keys by the number of keys in an octave, we get the number of octaves:

88 keys \ 12 keys per octave = 7 octaves with 4 extra keys

Therefore, a piano with 88 keys has 7 complete octaves. The leftover 4 keys indicate that the piano does not have a complete eighth octave.
