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

Answers

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.

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

Answers

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.

list 2 object that produce gamma rays in space

Answers

Answer:

object number 1: SOURCES OF GAMMA RAYS

object number 2: COMPOSITION OF PLANETS

Explanation:

Sources of Gamma Rays: Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes. On Earth, gamma waves are generated by nuclear explosions, lightning, and the less dramatic activity of radioactive decay.

Composition Of Planets: Scientists can use gamma rays to determine the elements on other planets. The Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) Gamma-Ray Spectrometer (GRS) can measure gamma rays emitted by the nuclei of atoms on planet Mercury's surface that are struck by cosmic rays. When struck by cosmic rays, chemical elements in soils and rocks emit uniquely identifiable signatures of energy in the form of gamma rays. These data can help scientists look for geologically important elements such as hydrogen, magnesium, silicon, oxygen, iron, titanium, sodium, and calcium.

GAMMA RAYS

They are formed by the universe's hottest and most energetic objects, such as neutron stars and pulsars, supernova explosions, and black-hole regions.

Over time, what will to happen to the populations of light and dark moths on light trees?​

Answers

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.

The polysaccharide that is responsible for the strong structural nature of plant cell walls is

Answers

Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant's life style. The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited. A cortical array of microtubules can determine the orientation of newly deposited cellulose microfibrils, which in turn determines directional cell expansion and therefore the final shape of the cell and, ultimately, of the plant as a whole.

The polysaccharide that is responsible for the strong structural nature of cell walls of plants is cellulose.

The cellulose is an organic molecule that is made up of several units of glucose monomer. The cellulose which make up a large percentage of plant cell walls are composed of a network of several units of glucose monomer that are tightly linked together.

The cellulose, as well as lignin and hemicellulose, which constitutes the tensile fibers in the cell walls of plants, is the polysaccharide responsible for the strong structural nature of plant cell walls.
