3. Describe the overall trend of the graph.
Here the graph is showing increasing trend i.e; the population is increasing year-on-year. Follow the trend from left to right and state whether it is going up, down, or staying the same to explain the graph.
A trendline is a line drawn above or below pivot highs or lows to indicate the price's primary direction. Support and resistance in any time frame are represented visually by trendlines. They depict patterns during times of price contraction and show the direction and pace of the price.
Your best chart for displaying trends over time is a line chart. The most effective visual display for highlighting change over time is a line chart. Think about two variables, one on each axis: vertical and horizontal.
Three main graph types used to visually depict data in biology are: The scatter plot, Linear graph , a bar graph.

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.
so we can conclude that The ozone layer shields us from the harmful effects of excessive UV radiation, which can lead to sunburn, skin cancer, and eye damage.

Bioindicators are used to evaluate the state of the environment and how it changes over time. They include biological processes, species, or communities.
Lichens are one type of bioindicator. These plants are extremely vulnerable to airborne since they grow on surfaces like dirt, rocks, and trees. This is so that they may get the majority of their nutrition from the air.

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.

Construct a basic pathway for blood flow in a human body using heart, arteries and veins.
Blood is forced into the pulmonary artery by the ventricle when it contracts, passing via the pulmonic valve. Blood is transported through the pulmonary artery to the lungs, where it "gathers" oxygen. It then exits the lungs and travels through the pulmonary vein back to the heart. Blood flows into the left atrium.

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

Pepsin- Pepsin is a stomach digestive enzyme used to break down proteins in food that has been consumed. Pepsin is produced by the main cells of the stomach as pepsinogen, an inactive zymogen. The stomach's lining's parietal cells release hydrochloric acid, which reduces the pH of a stomach.
