Gated ion channels are open and close in response to a stimulus.
What is a stimulus?A stimulus in physiology is a perceptible alteration in the physical or chemical composition of an organism's internal or external environment. Sensitivity refers to an organism's or organ's capacity to recognize external stimuli and respond appropriately (excitability). As with touch receptors in the skin or light receptors in the eyes, sensory receptors can pick up information from both within and outside the body. Chemoreceptors and mechanoreceptors are examples of internal sensory receptors. A stimulus can trigger a response via stimulus transduction when it is recognized by a sensory receptor.

Scientist combine engineer skin in a laboratory to treat severe Burns and other types of skin injuries despite all engineer tissues grown from living cells the cellular process enables the so to grow in develop into tissue is
Answer:
mitosis
Explanation:
The cellular process that enables the cells to grow and develop into tissue is mitosis.
Mitosis involves the division of the vegetative cells of the body and is important for the growth and development of organisms as well as in the healing of wounds or the replacement of damaged cells/tissues.
Hence, in treating burns and other types of skin injuries, the cells of the skin are stimulated to divide rapidly by mitosis so as to replace the damaged cells due to the injury. By doing so, the injured area heals.
Answer True or False.
Cancer cells show no contact inhibition. Therefore, cell growth and division does not stop.
True
False
Answer:
Cancer cells are immortal and keep on dividing for an unlimited number of times. Cancer cells pile on top of one another and grow in multiple layers, forming a tumor. Cancer cells keep on dividing, even when stimulatory growth factors are absent, and they do not respond to inhibitory growth factors.
The statement "Cancer cells show no contact inhibition. Therefore, cell growth and division do not stop" is true.
What are cancer cells?
Cancer cells are abnormal cells that grow rapidly without stopping. These cells cause tumors because of unstoppable cell growth.
The amount of times that cancer cells can divide is infinite because they are immortal. A tumor is created when cancer cells stack on top of one another and grow in numerous layers.
Even in the absence of stimulator growth factors, cancer cells continue to divide and do not react to inhibitory growth factors. No contact inhibition is a mechanism that is used for stropping cancer and this inhibition is not present in cancer cells, that's why they divide rapidly.
Therefore, the statement is true.

What is the function of the structure identified by the red arrow?
Answer:
The structure shown by the red arrow is cell membrane.
In biology, cell membrane refers to the thin layer, which develops the external boundary of a living cell. It has three primary functions, which are as follows:
1. It comprises channels and receptors, which permits particular molecules like nutrients, ions, metabolic components, and wastes to pass between the cell and the outside environment.
2. It prevents toxic components from entering the cell.
3. They distinguish essential but incompatible metabolic procedures conducted within the cell.
Explanation:
The function of the structure identified by the red arrow is to store the genetic material (this structure is the cell nucleus).
The cell nucleus is an organelle found in eukaryotic organisms whose function is to store the genetic material (DNA).The DNA within the cell nucleus contains genes that are expressed during transcription and translation to produce proteins.The differential expression of genes determines the phenotypic features of cells.In conclusion, the function of the structure identified by the red arrow is to store the genetic material (this structure is the cell nucleus).

people of india confound traditional racial categories because they fit most closely in terms of biological characteristics with people from europe, yet many have dark skin. '
Indians may closely resemble Europeans in terms of biological traits due to genetic allele frequencies.
The oldest skeleton from Europe that has been found so far is anatomically modern and dates to between 34,000 and 36,000 years ago. It was found in Romania's Carpathian Mountains. Conclusions drawn from the fossil evidence are supported and expanded by data already available on human genetic variation.
The conventional racial divisions, according to some observers, is biologically and genetically justified by these patterns of variation. According to their claims, the distribution of humans among sub-Saharan Africans, European, West Asians, and North Africans, Eastern Asians, Polynesians and other Oceanian residents, and Native Americans largely corresponds to the grouping of the continents.

what is a component of cell theories
○Cells come from bacteria
○cells come from cells
○cells come from nonliving matter
○cells come from non-cells
Answer:
cells come from cells
Explanation:
The component of cell theories is that all cells come from already existing cells by division.
The component of the cell is that it is the primary element of life and that all the living things are made of one or more cells.
New cells come from the old ones by division and it means that no living thing can come into being through the non-living thing.

what would be the result in macromolecule structure and function if the world was based on a small nonpolar lipid
Changes is macro molecule structures are expected among other things.
Briefing :There would be significant changes to proteins and carbohydrates if the Earth were built on a tiny non-polar lipid rather than water. Basic alterations in an organism might include solubility, catabolism, metabolism, and absorption. Because there aren't enough dissolved media, a lot of water-soluble material would become immobile.
However, other stuff that is soluble in fat will be very mobile and well absorbed. Sessile organisms that rely on nutrients that are dissolved in water for absorption, such as trees, will lose this capability. Finally, abiotic variables like precipitation and rock weathering will be affected. There will no longer be polar cap freezing or ice melting, and there will be an influx of a non-evaporating liquid.
