In recent years, people have become concerned over the loss of
ultraviolet rays from the sun.
because it protects the earth from damaging
1. Ozone
2. carbon dioxide
3. nitrous oxide
Answer:
1. Ozone
Explanation:
Ozone is a substance with the chemical formula, O3, found in the stratospheric part of the atmosphere. It functions to prevent the harmful ultraviolet (UV) radiation from the sun from reaching the Earth. However, due to anthropogenic activities i.e. human activities that releases greenhouse gases e.g. CO2, CFC etc. the protective function of the ozone layer is wavering.
Hence, based on this question, people are concerned over the fact that this OZONE layer is depleting, hence, risking the exposure to the harmful radiation from the sun.

the average phosphate molecule spends 20000 to 100000 years cycling through the ocean. To speed the replenishment of the soil, farmers include large amounts of phosphate fertilizers which can runoff into streams, rivers, and the sea. What is a possible side effect of this?
Excess phosphate fertilizer produces a shortage across the entire region and hinders other agriculture
Excess phosphate fertilizer causes algae growth and oxygen decline, leading to fish kills and deadzones.
Excess phosphate washes up on the beaches, ruining the sand and shoreline.
Excess phosphate fertilizer causes rapid seaweed growth with clogs up the motors of boats and large sea-going vessels.

im a student aid and i just graded the paper with this question
A geneticist is trying to recreate a strand of DNA from a crime scene investigation. The strand of DNA recovered from the scene was 1800 bases long. The geneticist has determined that the strand contained 425 thymine
nucleotides. Based on this information, identify the number of cytosine nucleotides
Answer:
475
Explanation:
The strand is only made up of Adenine, Thymine, Cytosine and Guanine. There will be the same number of Adenine as there are Thymine and the same number of Cytosine as there are Guanine.
We know there are 425 Thymine. This means there are also 425 Adenine. Therefore, you would subtract 850 (425x2) from 1800 to find the amount of Cytosine and Guanine left, which is 950.
Out of the 950, half will be Cytosine and half Guanine. 950/2 is 475.

Explanation:
For example, a friend of yours goes to the gym and takes a 30-minute, cardio interval training class. While switching between doing high-intensity push-ups, jumping jacks, and weight training, she notices that there is a burning sensation in her muscles. The burning is due to the buildup oflactate in the muscle tissue, a result of her muscles supplying ATPanaerobically . What is true about this pathway for forming ATP
Answer:
No oxygen is required.
Explanation:
This pathway for forming ATP needs no oxygen and the ATP that is produced are in very low concentration. The low amount of ATP production occurs when the cell goes for anaerobic respiration in which the cell produces less ATP. This type of ATP production occurs only when the body requires ATP quickly so that's why the body uses this type of respiration during exercise and running activities etc.

individual developing
A. O a type of cancer.
B.
into two or more organisms.
C.
only one sex cell.
D.
a single set of chromosomes.
Answer:
A
Explanation:
Cancer is the uncontrolled increase of cells, so when the rate of mitosis increases, so does the number of cells. This means A is the answer.
Uncontrolled cell growth is cancer. Gene mutations can increase the pace of cell division or suppress natural mechanisms that keep the body in check, like cell cycle arrest or programmed cell death. Thus, option A is correct.
What results, uncontrolled increase in the rate of mitosis?The cell's size, the presence of neighboring cells, and other chemical stimulators are three of the key elements in mitotic regulation.
Numerous mitogens are involved in regulating mitosis. Therefore, cell size, cell existence, and chemical stimulators are the proper answers.
When cancer cells develop in body tissues, they undergo aberrant cell growth patterns known as hyperplasia and dysplasia.
An increase in the quantity of cells in an organ or tissue that look normal under a microscope is known as hyperplasia.
Therefore, An abnormal and uncontrolled increase in the rate of mitosis is frequently associated with an individual developing cancers.

Over time, what will to happen to the populations of light and dark moths on light trees?
Answer:
Explanation:white moths will be spotted easier and killed and the population would drop while the dark moths population will rise
The population of white moths at the light tress will increase over time with the process of natural selection.
The trees are a light color population. Dark moths are unable to camouflage with the tress, while white moths camouflage with the trees.
What happens to white moths?The white and black moths at the tree are an example of a tree ecosystem. The moths are the target for the predators.
The process of natural selection is the evolutionary process with the survival of the fittest. The species that are able to survive in the inappropriate conditions are able to evolve.
In the tree ecosystem, the white moths are camouflaged with the trees. They will not be an easy target for predators. They will survive with the theory of natural selection.
The black moths are not camouflaged with the tree ecosystem. They are easily identified by the predators and are killed.
Thus, white moths are the fittest and with natural selection, they evolve.
Therefore, the population of white moths at the light tress will increase with natural selection.

Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in the base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valin. As a result of this mutation the individual’s blood cells take on a sickle shape under certain conditions Which type of mutation causes sickle cell anemia
Answer:
POINT MUTATION (SUBSTITUTION)
Explanation:
A point mutation is that mutation which involves only one nucleotide base. Point mutation can, however, occur in different ways such as SUBSTITUTION. Substitution point mutation is that which involves the replacement of a single nucleotide base by another in a gene sequence.
This is the case in this question regarding the mutation that causes sickle cell anaemia. According to this question, Sickle cell anemia is a disease that occurs when a mutation in the base pair of the hemoglobin beta gene causes a SINGLE replacement of GLUTAMIC ACID (Glu) by VALINE (Val). This shows that it is a type of SUBSTITUTION POINT MUTATION.
