The ozone layer shields us from the harmful effects of impudent and UV radiation, which can show sunburn, skin cancer, and eye damage.
What shields the Earth from the harmful effects of solar winds?
Earth's magnetic field, or magnetosphere, extends from the planet's core out into space, where it meets the solar wind, a brook of charged particles emitted by the sun. The ozone layer buckles us from the harmful effects of immoderate UV radiation, which can lead to sunburn, skin cancer, and eye damage. Earth's magnetic field serves to divert most of the solar wind, whose charged particles would else strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, ozone layer stream of charged particles emanating from the Sun.

Pls help me all u have to do is tell me what is wrong in the cell that is causing this to happen
Plasmolysis is the process of the protoplasm of a plant cell contracting or shrinking, which is brought on by the cell's loss of water.Osmosis can lead to outcomes like plasmolysis, which is a rare occurrence in nature.
What causes cells to stop growing?
According to research coauthor and geneticist at Harvard Medical School Stephen Elledge, cell death — the stopping of cells from growing and dividing — is caused by extreme stress and genetic damage.Specifically because to water pressure, plant cells maintain their form.Water is actively pumped into plant cells to maintain their rigidity.The cellulose and pectin-based cell wall's durability prevents the cells from bursting under pressure.All living cells need a little chemical known as adenosine triphosphate (ATP) as fuel, which is one of the earliest and most persistent lessons that students learn in biology class. Numerous genes play a role in regulating cell division and development.The cell cycle is the orderly, sequential process by which a cell duplicates itself.This process is tightly regulated to guarantee that the DNA of a dividing cell is accurately duplicated, that any DNA errors are corrected, and that each daughter cell obtains a complete set of chromosomes.Checkpoints, also known as restriction points, are locations in the cell cycle when specific genes can check for issues and stop the cycle for repairs if something is wrong. A cell may self-destruct if there is a DNA mistake that cannot be corrected (apoptosis).Apoptosis is a process that occurs frequently throughout life to help the body get rid of cells that are no longer functional or that are unnecessary.A type of white blood cell known as a macrophage dissects and recycles cells that have undergone apoptosis.Apoptosis plays a critical function in the development of the embryo and the maintenance of adult tissues, as well as protecting the body by eliminating genetically compromised cells that could cause cancer. Diseases like cancer can result from an alteration in the cell cycle's regular regulation.Cells can divide randomly and collect genetic mistakes that can result in a malignant tumor when the cell cycle is out of control.To learn about cells refer

If a mutation occurs in a gene that codes for a protein, what might happen to that protein after the mutation has occurred?
a.
The gene and mRNA do not change, but the protein does.
b.
The mRNA changes but the amino acid sequence does not.
c.
The protein might have different amino acids because the mRNA had different codons.
d.
Nothing - mutations only cause changes in the DNA.
The gene and mRNA do not change, but the protein does. Option A.
When the mutated sequence is translated into protein the resulting protein is incomplete and shorter than normal. As a result, most nonsense mutations result in non-functional proteins. A genetic variant can prevent one or more proteins from functioning properly. By changing the instructions of genes to make proteins.
The variant may cause the protein to malfunction or not be produced at all. The mutation is the process that causes a permanent change in the DNA sequence. Changes in a gene's DNA sequence called mutations can change the amino acid sequence of the protein the gene encodes, but this is not always the case. Coding region mutations can have very different effects on an organism's phenotype. Some mutations in this region of DNA and RNA can result in beneficial changes.

The distance used to determine the work is less.
What is work done?When an external force drives an object a specific distance, it transfers a certain amount of energy to the object, which is known as work. The amount of work performed on an object is a measure of the energy transmitted to it. Work is defined as the sum of the force component acting in the displacement direction and the displacement magnitude (d).
A measurement of the energy that is transferred when an object is moved over a distance by an external force, at least some of which is applied in the direction of the displacement.
