then the answers are memory , helper and cytotoxic .

Cytotoxic, helper, and regulatory T cells are the three primary subtypes of T cells. They each play a unique part in the immunological response.

A co-receptor on the cell surface of cytotoxic T cells (Tc cells) is named CD8, the white blood cell subtype.

T cells are produced by stem cells in the bone marrow and are a component of the immune system. They may aid in the fight against cancer and protect the body from infection also known as a thymocyte.  

T lymphocyte cells circulate until they come into contact with their particular antigen, rather than attacking all antigens at once.

Therefore, T cells are essential for developing immunity to foreign chemicals.

The immune system fights infection.

The organ system that controls and coordinates messages in the body is called the nervous system .

The endocrine system controls growth, development, and other related processes.

The organ system that breaks down and absorbs nutrients is called the digestive system .

Answer:

A, A, C, and B or The  ✔ lymphatic/immune system fights infection.  The organ system that controls and coordinates messages in the body is called the  ✔ nervous system . The  ✔ endocrine system  controls growth, development, and other related processes.  The organ system that breaks down and absorbs nutrients is called the  ✔ digestive system .

Explanation:

The immune system is a network of biological processes that protects an organism from diseases. It detects and responds to a wide variety of pathogens, from viruses to parasitic worms, as well as cancer cells and objects such as wood splinters, distinguishing them from the organism's own healthy tissue. Many species have two major subsystems of the immune system. The innate immune system provides a preconfigured response to broad groups of situations and stimuli. The adaptive immune system provides a tailored response to each stimulus by learning to recognize molecules it has previously encountered. Both use molecules and cells to perform their functions.

The nervous system or the neural system is a complex network of neurons specialized to carry messages. The complexity of the nervous system increases as we move towards higher animals.

The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. The study of the endocrine system and its disorders is known as endocrinology.

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has three stages: the cephalic phase, the gastric phase, and the intestinal phase.

Answer:

Explanation:

One of the changes in the immune system that rarely accompanies aging is an increase in the number of white blood cells.

Aging reduces the immune system's efficiency, making the elderly more susceptible to infections, cancer, and autoimmune diseases. As the body ages, the immune system becomes less responsive to threats, and infections become more frequent. This reduction in immune function is known as immunosenescence, and it is one of the most common aging-related changes. Additionally, aging causes a decrease in the thymus gland's activity, which is responsible for producing T-cells. This leads to a decline in the production of T-cells, which play a critical role in fighting infections. Therefore, the body's ability to recognize and fight infections decreases with age. Another change in the immune system that rarely accompanies aging is a decrease in the diversity of the immune system. With age, the immune system becomes less diverse, which means that it is less able to recognize and fight new infections. This is because the immune system is more prone to recognize and respond to infections it has encountered previously. Additionally, as we age, the number of naïve T-cells declines, which means that the immune system is less able to recognize new infections. In conclusion, aging leads to a decline in the immune system's efficiency, leading to increased susceptibility to infections and other diseases.

Answer:

D. Jerome has Duchenne muscular dystrophy, which is sex-linked. Frank has Huntington’s, which is dominant.

Explanation:

Duchenne muscular dystrophy (DMD) and Huntington's Disease (HD) are both neuro-degenerative diseases. Both are caused by mutations in exons that encode for proteins.

DMD is sex-linked because the mutation that causes this disease is found on the X-chromosome. The diseases specifically affects muscles and cause muscular dystrophy, hence the name.

Huntington's disease is autosomal dominant and the mutation is found on chromosome number 4. The Huntington protein is involved in numerous processes and the mutation causes progressive nuero-degeneration.

Explanation:

High blood cholesterol levels increase the risk of a myocardial infarction (heart attack) because cholesterol plays a crucial role in the development of atherosclerosis.

It is the underlying process leading to the formation of coronary artery plaques. These plaques can eventually rupture, leading to the formation of blood clots that block blood flow to the heart muscle, resulting in a heart attack. Elevated levels of cholesterol, particularly low-density lipoprotein (LDL) cholesterol, contribute to the development of atherosclerosis. LDL cholesterol is transported in the blood and can infiltrate the inner lining of arterial walls. Over time, LDL cholesterol can accumulate and undergo oxidation, triggering an inflammatory response. This leads to the recruitment of immune cells, such as macrophages, which engulf the oxidized LDL cholesterol and form foam cells. These foam cells, along with other cellular debris, create fatty streaks within the arterial wall.

As the fatty streaks progress, smooth muscle cells migrate to the site and produce collagen, forming a fibrous cap over the plaque. However, if the plaque becomes unstable, it can rupture, exposing its contents to the bloodstream. This can initiate the formation of a blood clot or thrombus at the site of the plaque rupture. If the clot completely occludes a coronary artery supplying blood to the heart muscle, it can result in a myocardial infarction.

The presence of high blood cholesterol levels contributes to the accumulation of cholesterol within arterial walls, promoting the development and progression of atherosclerosis. Thus, managing cholesterol levels through lifestyle modifications (e.g., healthy diet, regular exercise) and, if necessary, medication interventions (e.g., statins) is crucial in reducing the risk of myocardial infarction and maintaining cardiovascular health.
