Six elements account for 99% of the mass of the human body. The acronym CHNOPS refers to the following elements:

C for carbon,

H for hydrogen,

N for nitrogen,

Or for oxygen,

P for phosphorus

and S for sulfur.

Oxygen is the most abundant element in the human body, making up about 65% of a person's mass. In addition to being a component of water (essential for biochemical reactions in the human body), oxygen is essential for cellular respiration.

Carbon is contained in all organic compounds, which is why carbon is the second most abundant element in the body, accounting for around 18% of body mass. Carbon is found in organic macromolecules, such as proteins, carbohydrates, lipids, and nucleic acids.

Hydrogen atoms make up about 10% of body mass. Hydrogen is in water, in the composition of proteins, carbohydrates, lipids, and nucleic acids, and it is also an important electron carrier.

Nitrogen is about 3.3% of body mass. It is found in proteins and nucleic acids. This element provides materials for the construction and maintenance of all organs and tissues and participates in the formation of hormones and enzymes.

Potassium makes up approximately 0.2 to 0.4% of a person's mass. This element is important as a cofactor and also in processes of the nervous system such as nerve conduction. Potassium is an important electrolyte as it helps nerve function and muscle contraction and helps keep your heart rate steady.

Finally, we have that sulfur is found in some amino acids and proteins. Sulfur is approximately 0.2 to 0.3% of body mass. Then, Sulfur is a mineral necessary for the formation of collagen, a protein that is part of the skin, bones, tendons, and ligaments.

The effect of this environmental change is A, decreased genetic variation.

Environmental change can have a number of effects on genetic variation. One of the most common effects is a decrease in genetic variation. This can happen when a population is divided into smaller groups, each of which is exposed to different environmental conditions.

This can lead to the selection of different genes in each group, and over time, the groups can become genetically distinct. Genetic drift is a random change in the frequency of genes in a population. It can happen when a population is small, and it can lead to a decrease in genetic variation.

1 can be labeled as an amino acid, 2 as the ribosome, and 3 as the anticodon.

The image depicts the process or translation of genetic codes, otherwise known as protein synthesis.

During translation, mRNA, a structure that contains the genetic codes to be translated, binds to the ribosome. Then, another RNA, the tRNA which carries the anticodons for the genetic codes also binds. The tRNA also carries the amino acids specific for each genetic code.

The translation machinery then reads the genetic codes one after the other. each time the anticodon on the tRNA matches the genetic codes, the amino acid is released. Successive amino acids are linked by peptide bonds. Thereafter, the growing chain of amino acid exit the translation bubble.  

Thus, the labels for 1, 2, and 3 in the image would be as follows:

A gene is a section of a DNA molecule that contains the information to code for one specific protein.

Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body.

DNA is the chemical name for the molecule that carries genetic instructions in all living things.

The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix

The sequence of bases in the DNA molecule called gene determines the sequence of amino acids in a protein.

Glacial ice eroded the rock as it slowly flowed downhill. The accumulation of snow in frigid conditions such as arctic regions and high-altitude mountains produces glacial ice, a solid form of water. Snow accumulates weight over time, becoming solid ice that can flow under its own weight and destroy terrain.

Mountains and valleys are formed by glacial ice, which also leaves behind distinctive features such as moraines and glacial lakes. It is an important part of Earth's water cycle and has significantly influenced the world's geology and climate history.

Here is an analysis of the changes in vegetation and species diversity based on the data:

In the first years after logging, the area was dominated by grasses, with 32 species present after 1 year. Shrubs and trees were initially absent. This indicates that grasses rapidly colonized the disturbed area after logging.

Over time, the number of grass species declined as shrubs and trees became established. Shrubs first appeared after 5 years and gradually increased, with 18 species present after 45 years. Trees were absent for the first 15 years but then increased to 24 species after 45 years.

The total number of species showed a steady increase over the 45 years, from 32 species initially to a maximum of 77 species after 45 years. This indicates that species diversity was low immediately following the disturbance but gradually recovered and surpassed the original diversity levels.

The pattern of changes suggests that after the initial disturbance of logging, grasses were the first vegetation to recover and colonize the open area. Then over time, shrubs and trees established and the plant community transitioned from grasses to shrubs to trees. This successional progression from early to later species resulted in an overall increase in species diversity as different types of plants colonized the area.

In summary, the key conclusions supported by the data are:

A missense mutation is a Genetic alteration that causes the protein produced to encode a different amino acid at a specific location. Certain missense mutations change how the resulting protein functions.

While mutations always result in a change in the DNA sequence, they do not necessarily have a noticeable impact on the organism or alter the resulting protein. Since most amino acids can be encoded by two or more distinct codons, this is possible.

The ability to properly identify and characterise the majority of sequence changes makes direct DNA sequencing, in theory, the method for mutation identification with the highest degree of accuracy.
