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).

(True/False) A human’s cells do not all have the same DNA.
Answer: false
Explanation:
All has same DNA
It is false that human cells do not all have the same DNA.
DNA:Deoxyribonucleic acid, also called DNA, is a biological molecule that stores genetic information in living cells. The DNA contains genes responsible for inheritance of certain traits. However, in humans, all cells contain the same DNA sequence. Specialization occurs because the DNA are expressed differently and at different times.Therefore, it is false that human cells do not all have the same DNA.

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.
which of the following is a true statement about lipids in cell membrane?

The oldest rocks on Earth are REALLY old - about 4.6 billion years old - but all of the oldest ones are found on land and not in the ocean. Around the mid-ocean ridge, the rocks are very young (only 9 million years old). Why is there a difference in the ages of rocks on land versus in the ocean?
Why are the oldest rocks on the ocean floor only 200 million years old while the oldest rocks on the continents are almost 4 billion years old?
Explanation: The oldest oceanic crust is about 260 million years old. This sounds old but is actually very young compared to the oldest continental rocks, which are 4 billion years old. ... It is due to the process of subduction; oceanic crust tends to get colder and denser with age as it spreads off the mid-ocean ridges.

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.

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 hormone, released from the pancreas in response to a low blood glucose level, acts to raise blood glucose back to normal?.
When blood glucose levels fall too low (low blood glucose), the pancreas pumps out more glucagon. This hormone helps blood glucose rise back up in multiple ways: It causes the liver to convert stored glucose into a usable form and then release it into the bloodstream.

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.
