DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.
What is protein synthesis?
Cells create proteins through a process known as protein synthesis. Transcription and translation take place simultaneously. The conversion of genetic information from DNA to mRNA in the nucleus is known as transcription.
Initiation, elongation, and termination are its three stages. Following processing, the mRNA transports the instructions to a ribosome in the cytoplasm.
The ribosome, which is made up of proteins and rRNA, is where translation happens. The mRNA's instructions are read during translation, and tRNA then transports the appropriate sequence of amino acids to the ribosome. rRNA then facilitates the formation of bonds between the amino acids, resulting in a polypeptide chain.
A polypeptide chain may be further processed to create the finished protein after it has been created.
Therefore, DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.

promoter and termination regions
stop codon
Answers
The promoter region of a gene is not found within the mRNA transcript.
The correct answer is promoter region
The promoter region is located at the beginning of the gene and is responsible for initiating transcription by providing a binding site for RNA polymerase. After transcription is initiated, the RNA polymerase reads and transcribes the coding region of the gene into mRNA. The termination region, on the other hand, is found at the end of the gene and signals the end of transcription. The stop codon is also found within the mRNA transcript and signals the end of protein synthesis during translation. Therefore, the correct answer is the promoter region.

Living things should be compared and classified by genetic similarities, suggesting that very different living organisms are biologically related by evolutionist.
The theory of evolution is referred to as evolutionism. Its precise definition has evolved throughout time as the science of evolution has advanced. It was used to characterise the concept in the nineteenth century that organisms consciously developed themselves via gradual hereditary change.
Natural selection, according to evolutionists, is the mechanism by which all organic life evolves from generation to generation. This notion is the foundation of evolutionist theories. The three fundamental components of Charles Darwin's theory of evolution were that variation occurs randomly among members of a species, that an individual's features could be transmitted by its descendants, and that the battle for survival would allow only those with advantageous traits to survive.

Ecological problem is one of the most important issues nowadays. Human activities have a negative impact on the environment. Humanity currently faces problems with air, water, and lands pollution, unreasonable agricultural systems, deforestation, and others. As a result, the number of available natural resources is decreasing. Another negative consequence of human activities is the process of global warming and global climate changes. These changes affect the whole Earth and might result in adverse consequences for people and wild nature
Another important action we perform to improve the situation with water is avoiding water pollution. Our family refused to use cleaning detergents with phosphates as it is known that these substances are harmful to human health. Moreover, it is difficult to eliminate these compounds from water. Therefore, phosphates in the water get to nature and poison living organisms. Thus, it is better to use detergents without phosphates. It helps to keep the healthy and to reduce water pollution
Except for water pollution, there are a lot of other problems that need to be solved. One of them is waste deposits. These deposits occupy a large area. Different wastes need different (however, always significant) times to decompose. Besides, while decomposing, a lot of harmful compounds appear. These compounds poison the land and can get to the water. In the last decades, a lot of programs of waste separation appeared. People are asked to separate the waste: to combine plastic with plastic, organic with organic, and paper with paper. Different wastes are treated in different ways, which allows cutting pollution. For example, plastic can be remolded and used again, while it requires hundreds of years for its degradation in nature. Moreover, during this process, a lot of harmful products release (Law and Thompson 144). Thus, it is better to separate plastic material and recycle it. It would be even better not to use plastic at all, and when it is possible, try to use biopolymers instead.

Answers
Organ in which alcohol absorption occurs: Stomach and small intestine walls Blood stream Elimination of alcohol from the body: Liver
When a person drinks, the body absorbs alcohol, circulates it, and eventually eliminates it. Below are the organs or systems in the body where each of these steps takes place:
The organ in which alcohol absorption occurs: Alcohol is absorbed by the stomach and small intestine walls.
The bloodstream is where alcohol absorption occurs. The blood circulates throughout the body and transports alcohol from the stomach and small intestines to other parts of the body.
When alcohol enters the bloodstream, it is diluted, making it easier for the liver to break it down and eliminate it.
In addition, when alcohol enters the bloodstream, it may be found in all tissues of the body, including the brain, kidneys, lungs, and heart. The elimination of alcohol from the body: The liver is the primary organ responsible for metabolizing, or breaking down, alcohol.
Alcohol is eliminated from the body by the liver. The liver breaks down alcohol using enzymes that convert it to acetaldehyde, which is a toxic substance. The liver then converts acetaldehyde into acetic acid, which is a less toxic substance. Finally, acetic acid is broken down into carbon dioxide and water, which are eliminated from the body through urine and exhalation.

if the codon aaa is changed to aag, it still codes for the amino acid lysine; this is an example of a
Answers
Yes, this is an example of a silent mutation or synonymous mutation, where the DNA sequence changes, but the amino acid produced does not. In this case, the codon AAA codes for the amino acid Lysine, and changing it to AAG also codes for the amino acid Lysine.
If the codon AAA is changed to AAG, it still codes for the amino acid lysine. A codon is a series of three nucleotides that correspond to a particular amino acid or stop signal during protein synthesis. A codon, in genetics, is a set of three-nucleotide sequences in messenger RNA (mRNA) that encode specific amino acids during protein synthesis.Lysine is an amino acid with the chemical formula \(HO_2CCH(NH_2)(CH_2)_4NH_2\). It is a hydrophilic, basic amino acid with a molecular mass of 146.19 Da. It is one of the 20 amino acids that make up proteins. The codon that encodes it is AAA or AAG. These two codons code for the amino acid lysine.When there is a change in the codon AAA to AAG, the same amino acid, lysine, is still encoded. Because of the redundancy of the genetic code, many mutations have no impact on the organism's phenotype. These are called silent or synonymous mutations. These mutations are often thought of as mutations that have no effect on the organism's phenotype.

Values of 27.5 girls or greater are significantly high.
C. The result is significantly high, because 39 girls is greater than 27.5 girls. A result of 39 girls would suggest that the method is effective.
How do we solve for the standard deviation in the method of gender selection?a) The mean and standard deviation for the numbers of girls in groups of 42 births:
μ = np = 42 × 0.5 = 21.
σ = √(np×(1-p)) = √(42×0.5 × 0.5) = 3.24.
b) The range rule of thumb (also known as the empirical rule) states that for a normal distribution, nearly all of the data falls within three standard deviations of the mean. The range is then given by μ±2σ.
Significantly low: μ - 2σ = 21 - 2×3.24 = 14.5.
Significantly high: μ + 2σ = 21 + 2×3.24 = 27.5.
c) A result of 39 girls is significantly high, as it is greater than the upper range value of 27.5.
The result is significantly high, because 39 girls is greater than 27.5 girls. A result of 39 girls would suggest that the method is effective.

Answers
Approximately 40% of the energy of glucose is transferred to storage in ATP during aerobic cellular respiration, while the other 60% of the energy is transferred to heat.
During aerobic cellular respiration, glucose is broken down into carbon dioxideand water in the presence of oxygen to release energy. This energy is used to generate ATP (adenosine triphosphate), which is the primary source of energy for most cellular processes. However, not all of the energy released during cellular respiration is used to generate ATP. Approximately 40% of the energy of glucose is transferred to storage in ATP, while the remaining percentage of the energy is transferred to heat.
During aerobic cellular respiration, glucose is broken down into carbon dioxide and water, releasing energy in the form of ATP (adenosine triphosphate). About 40% of the energy from glucose is efficiently converted to ATP, which is then used to fuel various cellular processes. However, the remaining 60% of the energy is lost as heat, which is a less efficient transfer of energy.
In aerobic cellular respiration, 40% of the energy from glucose is transferred to ATP, while the remaining 60% is transferred to heat. This process highlights the fact that energy transfer is not always 100% efficient, and some energy is inevitably lost during the process.
