The amino acids in a protein polymer are connected by a covalent bond called a peptide bond that connects the carboxyl group of the first amino acid to the amino group of the second amino acid. Such successive amino acid bondings generate a protein polymer called a polypeptide.

A peptide bond is formed through a condensation reaction between the carboxyl group of one amino acid and the amino group of another amino acid. This bond results in the formation of a covalent linkage between the carbon and nitrogen atoms of the amino acids, creating a peptide bond. The successive formation of peptide bonds between amino acids leads to the generation of a polypeptide chain, which is the primary structure of a protein.

The main differences between type I and type II photoreactions following photo dynamic therapy are the mechanisms by which they cause damage to cells.

Type I photoreactions involve the transfer of energy from the photosensitizer to a nearby molecule, causing it to become an unstable free radical. This free radical can then react with other molecules, causing damage to cells. Type II photoreactions, on the other hand, involve the transfer of energy from the photosensitizer to molecular oxygen, creating a highly reactive form of oxygen known as singlet oxygen. Singlet oxygen can then react with and damage cellular components. One of the main advantages of using Laser light to generate damage oxidation of bases is that it allows for more targeted and precise treatment of cancerous cells. Laser light can be focused on a specific area, minimizing damage to surrounding healthy tissue. Additionally, Laser light can be used to activate photosensitizers that are selectively taken up by cancerous cells, further increasing the specificity of the treatment.

In order to focus on training the anaerobic glycolysis system during a training interval, a HR max % of 80-90% should be maintained. This is because anaerobic glycolysis is a system that relies on the breakdown of glucose without oxygen, leading to the production of lactate as a byproduct.

This system is utilized during high-intensity exercise, such as sprinting or weightlifting. By maintaining a high HR max %, the body is forced to rely on this system more heavily, leading to adaptations such as increased lactate threshold and improved muscular endurance.

However, it is important to note that training solely in this HR range can be taxing on the body and should be balanced with lower-intensity aerobic training for overall cardiovascular health. Additionally, it is important to gradually increase the intensity and duration of anaerobic training to prevent injury and allow for adequate recovery.

Mutations occur randomly at any place in the DNA sequence and may occur in any cell, hence option D is correct.

Any alteration in the DNA base sequence, also known as a heritable change in the genome, is referred to as a mutation.

The most frequent modification involves the replacement, insertion, rearrangement, or deletion of one or more bases. A mutant phenotype need not result from a mutation.

A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.

The major reason why the average human lifespans were less than 50 years until fairly recently is due to infectious diseases like tuberculosis, cholera and smallpox. It was also because the causes and cure of other major diseases like malaria and plague had not yet been found.  

The lifespan of an entire population of people is known as the life expectancy, while the lifespan of an individual is a measure of the length of a person's life. Until recent years, causes, modes of transmission and treatment of common diseases were not known. Access to good medical care was difficult and hygienic conditions then were very poor. For example, it wasn't until the mid-1800's that people came to know that washing of hands could stop the spread of diseases, and until the late 1800's doctors didn't adequately wash their hands before performing a surgery.

Unhygienic conditions also made it easier for deadly infectious diseases like the Bubonic plague, the Black plague and the Spanish flu to spread, further reducing the already low life expectancy.

Today, thanks to good hygiene, better understanding of transmission of microbes, environmental sanitations, early immunizations and access to clean water, life expectancy has increased.

We design a model that explains how your experiment demonstrated the transfer of genetic material from father to offspring. In our model, we clearly identify where the transfer of genes from parents to children took place, and in this practical way, we explain heredity.

Heredity is the biological system of transmission of certain characteristics of living beings between generations. For the full functioning of this structure, genes are needed – a piece of DNA (deoxyribonucleic acid) that houses genetic information.

Some properties can remain inactive for generations, which does not represent their extinction, only the forgetting of one or several genes. However, this does not make it impossible for the carrier of the dormant gene to pass it on to their descendants.

In addition, genetic information is capable of disappearing as a result of environmental and climate change. In these cases, natural selection processes directly affect heredity.

With this drawing, it was possible to visualize how gene transfer occurs in a normal situation.

Explanation:

The computation of Sheila 's velocity right after she gets thrown out of the bike is shown below:

1) The Physical principle: conservation of momentum.

If there is no net external force operating on a system, so the system's total momentum is conserved

The momentum, p, is a vector magnitude that is determined as the product of the mass by the velocity:

P = mv.

2) Taking into account therefore that there is no net force on the device, Sheila and the momentum of the bike are the identical pre and post collision.

Based on this, the calculation is as follows

Momentum before the collision:

       \(P_1 = (mass\ of\ Sheila + mass\ of\ the\ bike) \times velocity\)

       \(P_1 = (60kg + m) \times v_1\)

= 340 kg m/s

Now Momentum after the collision:

      \(P_2 = mass\ of\ sheila \times velocity\ of\ Sheila + mass\ of\ the\ bike \times velocity\ of\ the\ bike\)

\(P_2 = 60kg \times v_2 + m \times 0 = 60kg \times v_2\)

\(P_1 = P_2\)

\(= (60kg + m) \times v_1\)

\(= 60kg \times v_2\)

\(= 340 kg .\ m/s\)

\(= 60kg \times v_2\)

\(v_2 = \frac{340\ kg .\ m/s }{60\ kg}\)

= 5.7 m/s     

The velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

The given parameters;

The velocity of Sheila immediately after she is thrown from the bike is calculated as follows;

P = mv

where;

v is the velocity Sheila

\(v = \frac{P}{m} \\\\v = \frac{340}{60} \\\\v = 5.67 \ m/s\)

Thus, the velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

The diagram below represents a marine food web and a process that can harm the human population. Each circle represents an organism and the smaller dots inside them represent a toxic substance. The answer is: the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance.

The diagram represents a marine food web and a process that can harm the human population. This process is called biomagnification, which refers to the accumulation of toxins in organisms higher up on the food chain. The smaller dots inside the circles represent the toxic substances that are present in the organisms.

As the organisms at the lower trophic levels are eaten by the organisms at higher trophic levels, the toxic substances build up in their bodies. This can have a negative impact on humans who consume these organisms and the toxic substance.

This is because the toxins can have harmful effects on human health, such as causing cancer, birth defects, and other diseases. It is important to note that not all organisms in the food chain contain the same amount of toxins.

Those at higher trophic levels are able to metabolize the toxins more efficiently, making them safer for humans to consume compared to the organisms at lower trophic levels.

Therefore, it is crucial for us to be aware of the impact that our actions have on the environment and the food chain. We must take steps to reduce the amount of toxic substances that are released into the environment and to ensure that we consume food that is safe for our health and the health of the ecosystem.

The black blow fly takes around 264 degree-days to go from egg to adult.

The degree-day method is a way of calculating the time required for an organism to complete its development by summing up the number of degree-days required for development. It is calculated by subtracting the lower developmental threshold from the daily average temperature and summing it over a period of time.

The threshold temperature of black blowfly is 6°C, and it requires 11 days to develop into an adult at 27°C. Therefore, using the degree-day model, the number of degree-days required for its development is calculated as follows:

Degree days = (27°C - 6°C) x 11 days = 231 degree-days.

Therefore, it takes 231 degree-days for the black blowfly to develop from egg to adult at 27°C.
