Viruses differ from other pathogens because they are considered non-living.

Viruses are organisms that are incapable of reproducing on their own without a living host.

Viruses cannot undergo any of the characteristics of life outside a living host.

They, therefore, infect their host and use the mechanisms of the host to replicate themselves.

Therefore, viruses differ from other pathogens because they are considered non-living.

Answer: The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells. The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood. brainliest?

High antigenic variation through increased mutation rates. The biological property of a pathogen that could block the successful design of an effective vaccine is having a high antigenic variation through increased mutation rates.

Antigenic variation is a biological property of pathogens that involves changes in their antigenic structure, and it could block the successful design of an effective vaccine. Increased mutation rates cause the emergence of new antigenic variants that are different from previously existing ones. This makes it challenging to design a vaccine that targets all the existing antigenic variants, particularly if they are continually emerging or evolving. This means that even if an effective vaccine is intended for a particular variant, it may not be effective against other variants, limiting its efficacy.

Antigenic variation is common in RNA viruses like influenza viruses, human immunodeficiency virus (HIV), and coronaviruses like SARS-CoV-2, which causes COVID-19. The influenza virus has a high mutation rate, which explains why people need to get vaccinated annually because the vaccine efficacy reduces due to the emergence of new strains. HIV also undergoes antigenic variation, which makes it challenging to design a vaccine that targets all existing strains.

In conclusion, the high antigenic variation through increased mutation rates is a biological property of pathogens that could block the successful design of an effective vaccine.

The production of antibodies inside the lymphocytes starts at the ribosome (organelle) by joining amino acids together, creating peptide bonds, and forming the primary level structure polypeptide. The polypeptide bends and folds tertiary in the Golgi apparatus (organelle), to form the next level of structure. For instance, the secondary level of structure is formed by hydrogen bonds to create alpha helix or beta-pleated formations.

In order for an antibody to be released into the blood, a fully formed antibody will move from rough endoplasmic reticulum (organelle) to another organelle named Golgi apparatus to sort and be processed for shipment out of the cell. Antibodies transport from organelle to organelle and to the plasma membrane in a vesicle, which is made out of fatty acids-phospholipids.

Not only does it protect from UV rays, it also works to reduce the appearance of pores and fine lines over time, so you're actually improving your skin while wearing it.

Explanation:

Answer:

It prevents cancer.

Explanation:

UV rays penetrate the many layers of the epidermis, reaching the deep layers of our skin, which is meant to be protected. This activates pigment cells, releasing Melanin and darkening the skin.

When the UV rays penetrate these deep cells, it reacts similarly to radiation, denaturing and breaking apart DNA. If enough damage is done and the cell becomes irreparable a tumor forms.

Consistent exposure to UV rays has detrimental effects because it puts your skin cells through this same stress every day.

DNA is important in identifying genetic relationships within a group, but it alone is not sufficient to determine complex social constructs like race, whiteness, or property; the inclusion of social, cultural, and historical factors is crucial in understanding these concepts.

Biological anthropologists and genome scientists should consider the relationship between Europeans and Indigenous people in their research to provide a more comprehensive understanding of human genetic diversity and population history.

DNA analysis can provide valuable insights into genetic relationships within a group, such as determining genetic ancestry or identifying related individuals. However, race, whiteness, and property are social constructs that go beyond genetic factors and are shaped by historical, cultural, and socioeconomic factors. These concepts are complex and cannot be solely explained by genetic data. Therefore, it is important for researchers, including biological anthropologists and genome scientists, to recognize the limitations of genetic data and consider the broader social context when studying race, whiteness, and property.

In the context of researching Europeans and Indigenous people, it is crucial for researchers to acknowledge and incorporate the historical and ongoing relationships between these groups. This includes understanding colonization, displacement, and the impact of power dynamics on genetic diversity and health outcomes. By including this relationship in their research, scientists can contribute to a more accurate and nuanced understanding of human genetics and promote social and scientific equity.

Each trial results in more than one possible outcome is not a characteristic of a binomial distribution. Option B is correct.

This is not a characteristic of a binomial distribution. In a binomial distribution, each trial has two possible outcomes, commonly referred to as "success" and "failure." The key characteristic of a binomial distribution is that each trial has exactly two mutually exclusive and exhaustive outcomes.

The other characteristics of the binomial distribution are;

There is a set of n trials: The binomial distribution consists of a fixed number of trials, denoted by "n," where each trial follows the same probability distribution.

The trials are independent of each other: The outcome of one trial does not influence the outcome of another trial. Each trial is assumed to be independent.

Probability of success p is the same from one trial to another: The probability of success (denoted as "p") remains constant from one trial to another. In other words, the probability of the desired outcome remains unchanged throughout the series of trials.

Hence, B. is the correct option.
