Answer:

D

Explanation:

Interphase has 20 cells, prophase has 10 cells, metaphase has 3 cells, anaphase has 2 cells, and telophase has 1 cell, so the interphase has 100%, the prophase has 50%, the metaphase has 15%, the anaphase has 10%, and the telophase has 5%, while each phase will take 144 minutes.

The cell division takes place in order to divide the cells into either two or four cells, and here the total cells are 20, so as per that, the cells in each phase are derived, and taking the total phase of the cell division, which is 5, and dividing it with the total minute, which is 720, and multiplying with the number of times the phase takes place, the result is 144.

720/5×1=144

Hence, interphase has 20 cells, prophase has 10 cells, metaphase has 3 cells, anaphase has 2 cells, and telophase has 1 cell, so the interphase has 100%, the prophase has 50%, the metaphase has 15%, the anaphase has 10%, and the telophase has 5%, while each phase will take 144 minutes.

Genes and proteins related as D. One gene codes for one protein.

Genes are segments of DNA (deoxyribonucleic acid) that contain the genetic information that is passed from parents to offspring during reproduction. They are the fundamental units of heredity that determine the traits and characteristics of an organism. Genes are composed of nucleotide sequences that code for the production of specific proteins or functional RNA molecules. The sequence of nucleotides in a gene determines the sequence of amino acids in a protein, which ultimately determines its structure and function. Genes are located on chromosomes, which are long, thread-like structures made up of DNA and proteins. In humans, each cell typically contains 46 chromosomes arranged in 23 pairs, with one set inherited from each parent.

Here,

Genes are segments of DNA that provide the instructions for the synthesis of proteins. Proteins, on the other hand, are large molecules composed of long chains of amino acids. During the process of protein synthesis, the genetic information encoded in DNA is transcribed into RNA, which is then translated into a specific sequence of amino acids that makes up a protein.

Each gene codes for the production of a specific protein or a functional RNA molecule. This is known as the one gene-one protein hypothesis, which has been refined to the one gene-one polypeptide hypothesis to account for RNA molecules that are not translated into proteins. So, a gene provides the genetic code for the synthesis of a protein, which is made up of amino acids.

The scientific categorization of plants and animals by early scientists, including Carl Linnaeus, was connected to the categorization of humans into racial categories, perpetuating discrimination and oppression.

The connection between the scientific categorization of plants and animals to the attempt of early scientists to categorize humans into racial categories was that the same process used to classify plants and animals, particularly by Carl Linnaeus, was also used to classify humans, including his own race-based taxonomic system.

Linnaeus's Systema Naturae (1735), his taxonomic system of plants and animals, was the blueprint for his classification of humans into four categories. This was done based on physical characteristics such as skin color, hair type, facial structure, and other physical traits.

This form of classification allowed people to be divided into categories based on their race, and it enabled people to be categorized into a hierarchical ranking system that provided a scientific justification for discrimination and exploitation.

As a result, race was used as a tool for justifying unequal access to resources, power, and privilege. The social impact of this classification system is profound, and it continues to influence how people are perceived and treated today.

The system of racial classification has been used to justify slavery, colonialism, and genocide throughout history, and it has led to the marginalization and oppression of minority groups.

The Calvin cycle requires 9 ATP, 6 NADPH, and 6 inorganic phosphate (Pi) molecules.

The Calvin cycle is a series of reactions that occur in the stroma of chloroplasts during photosynthesis. It is responsible for converting carbon dioxide into glucose. In order to fuel this process, ATP is required as an energy source. The Calvin cycle uses a total of 9 molecules of ATP. These ATP molecules are generated during the light-dependent reactions of photosynthesis.

NADPH, which stands for nicotinamide adenine dinucleotide phosphate, is another essential molecule in the Calvin cycle. It serves as a reducing agent, providing electrons and hydrogen ions necessary for the conversion of carbon dioxide into glucose. The Calvin cycle consumes 6 molecules of NADPH to carry out its reactions. NADPH is produced during the light-dependent reactions of photosynthesis.

Inorganic phosphate (Pi) is a critical component in the Calvin cycle. It is involved in the phosphorylation of intermediates during the cycle. The Calvin cycle requires 6 molecules of inorganic phosphate (Pi) to proceed with its reactions. These inorganic phosphate molecules can be obtained from ATP hydrolysis or from other sources within the cell.

Explanation:

Coal mining, natural gas extraction, or both may have isolated impacts. landslides and Sinkholes are possible side effects of coal mining.

Natural gas production has been linked to the occurrence of earthquakes.

When both coal and natural gas are mined, methane gas is discharged into the air. Also can contaminate the groundwater. Consideration of these environmental impacts is essential when considering the merits of coal and natural gas as energy sources.

Additionally, Coal mining has a multiplicity of negative consequences for the environment, including the emission of sulfur dioxide and heavy metals into the air and water. However, methane leaks during natural gas extraction and transportation might amplify the effects of global warming.

The amino acid with a net charge of +0.09 at pH 7 is histidine.

The pKa values for the carboxyl and amino groups of histidine are 1.8 and 9.1, respectively. This means that at pH 7, the carboxyl group will be deprotonated and the amino group will be protonated. The side chain of histidine is an imidazole ring, which can act as both an acid and a base. At pH 7, the imidazole ring will be in a neutral state.

The net charge of histidine at pH 7 can be calculated as follows:

Net charge = +1 (protonated amino group) - 1 (deprotonated carboxyl group) + 0 (neutral imidazole ring)

= +0.09

The histidine residue is an important amino acid in proteins. It can act as a buffer, helping to keep the pH of a protein solution constant. It can also bind to metal ions and other small molecules. Histidine is also involved in many biological processes, such as signal transduction and protein folding.

The percentage of cytosine residues is 25%.

In DNA double helix, A always pairs with T and G always pairs with C.

Therefore, the number of adenine (A) is equal to the number of thymine (T), and the number of guanine (G) is equal to the number of cytosine (C).

This implies that, if there are 12 adenine residues in a DNA molecule, there will also be 12 thymine residues.

Therefore, we can calculate the percentage of cytosine residues as follows:

Number of guanine (G) = Number of cytosine (C)

Number of adenine (A) = Number of thymine (T)

Total number of nucleotides

= Number of adenine (A) + Number of thymine (T) + Number of guanine (G) + Number of cytosine (C)

= 12 + 12 + G + C

= 24 + G + C

Thus, percentage of cytosine residues is given by:

Percentage of cytosine (C) = (Number of cytosine / Total number of nucleotides) x 100

We can express the number of cytosine as:

G = C,

thus, 24 + G + C = 24 + 2C

Therefore, Percentage of cytosine residues:

= (C / (24 + 2C)) x 100

To get the value of C, we substitute G = C in the equation above:

24 + 2C

= 12 + 2C + C12

= C

Thus, Number of cytosine residues = 12

Percentage of cytosine residues:

= (12 / 24+2(12)) x 100

= (12 / 48) x 100

= 25%

Thus, the percentage of cytosine residues is 25%.

The process in which chromosomes line up during prophase I and inadvertently switch DNA on their long (or short) arm is called crossing over or recombination.

Crossing over is a process that takes place during meiosis in eukaryotes where homologous chromosomes exchange genetic material. In the process, the genetic information from one chromosome is transferred to another chromosome. The process results in new genetic combinations that can then be inherited by offspring.

In general, this process has three significant impacts:

Firstly, it helps to increase the genetic diversity of a population or species.

Secondly, it increases the chances of survival by developing new genetic combinations that are favorable in different environments.

And thirdly, it helps in the mapping of genes on chromosomes or linkage mapping.
