Blood flow is decreased below normal due to the build of of plaque in the arteries causing an increase in blood pressure.

Explanation:

When fats, cholesterol,calcium , water  builds up on the endothelial lining of the  Coronary arteries,reducing the diameter,and therefore impeding the flow of blood,these build up is called Plaque.The diseases condition that arise  from this called atherosclerosis.

With continue build up the plaque changes in the chemical components.becomes hardened, further reducing the diameter,blood volume available and therefore oxygen supply to the targeted tissues( cardiac muscles) of the heart.This leads to Ischemic heart diseases e.g chest pain-Angina. With these strokes and other complication may follows due to cut  off in oxygen and nutrients rich blood to the tissues of the brains  for the heart.

The impedance to the blood flow,forced load on the heart to pump blood and therefore High blood pressure.This is the problem with Steve CVS.

Two parents of mixed ethnicity have twins, one of which is born with very light skin and one of which is born with very dark skin. this is because of genetic recombination.

When two parents of mixed ethnicity have children, it is possible for the offspring to display a wide range of physical characteristics, including skin color. This is because of a process called genetic recombination. During the formation of reproductive cells, genetic material from each parent is randomly mixed and combined, leading to a unique set of genetic traits in each offspring. In the case of skin color, multiple genes contribute to the overall pigmentation of the skin.

The inheritance of skin color is not as straightforward as some other genetic traits, such as eye color, because it is influenced by multiple genes and is also affected by environmental factors, such as exposure to sunlight. The genes responsible for skin color are involved in the production and distribution of melanin, a pigment that gives color to the skin, hair, and eyes.

In the case of the twins born to parents of mixed ethnicity, it is possible that one twin inherited a greater proportion of genes that contribute to lighter skin color from both parents, while the other twin inherited a greater proportion of genes that contribute to darker skin color from both parents. Alternatively, it is possible that genetic recombination led to a unique combination of genes in each twin, resulting in different skin colors.

The steps of cell-mediated immunity are: 1. in lymph nodes, cytotoxic T cells encounter dendritic cells 2. In active cytotoxic T cell leaves lymph node 3. CTL secretes specialized molecules to penetrated infected host cell.

An essential part of the immune system that protects the body from intracellular infections like viruses and certain bacteria is cell-mediated immunity. It entails the coordination and activation of numerous immune cell types, primarily T lymphocytes.

Antigen-presenting cells (APCs) take up an antigen upon detection and offer it to T cells, which causes them to become activated. As a result, particular T cell subsets, such as cytotoxic T cells and helper T cells, grow and differentiate. Helper T cells aid in the coordination of immune responses, whereas cytotoxic T cells actively destroy infected cells. To contribute to the body's overall defence against infections, cell-mediated immunity is essential for getting rid of contaminated cells and offering enduring protection against pathogens.

1. In the lymph nodes, cytotoxic T cells encounter dendritic cells displaying epitope on MHC-I. The Tc cell is activated.

2. The active cytotoxic T cell (TCL) leaves the lymph node "looking" for infected host cells displaying the same epitope on their MHC-I. The CTL uses its surface receptors to recognize the infected cell.

3. The CTL secretes specialized molecules to penetrate the infected host cell causing programmed death.

These steps outline the process of cell-mediated immunity, where cytotoxic T cells recognize and eliminate infected host cells.

The baker's observations and measurements would provide more accurate insights into the effects of the different treatments on the bread's rise in the recipe.

In bread-making, yeast plays a crucial role in the rising process. When yeast is added to the dough, it undergoes fermentation, producing carbon dioxide gas that gets trapped in the dough, causing it to rise.

Based on the different treatments given to the dough before baking, here are some general expectations for the height of each loaf:

Loaf A: Since it is immediately baked without any additional time for the dough to rise, it may not have risen as much compared to the other loaves. The height of Loaf A might be relatively shorter.

Loaf B: By covering the dough with a damp cloth and leaving it in a warm area for an hour, the yeast has more time to ferment and produce carbon dioxide gas. The warm temperature provides an optimal environment for yeast activity, resulting in a better rise. Therefore, Loaf B is likely to have a higher height compared to Loaf A.

Loaf C: Placing the dough in the fridge slows down the fermentation process. While the yeast will still produce gas, the cold temperature inhibits its activity, resulting in a slower rise. As a result, Loaf C may have risen less than Loaf B, but potentially more than Loaf A

In the system developed by Carolus Linnaeus (1707-1778), a noun or adjective added to the genus name to distinguish a species is known as the species epithet.

The species epithet is the second part of a binomial name, also called a scientific name, which consists of the genus name followed by the species epithet. Linnaeus' system of binomial nomenclature was introduced in his work "Systema Naturae" and is still widely used in modern taxonomy.

The species epithet is chosen to describe a characteristic of the species or honor a person or place related to its discovery. It can be an adjective, a noun in the genitive case, or a word derived from a person's name. For example, in the scientific name Homo sapiens, "sapiens" is the species epithet that distinguishes our species from other species within the genus Homo. The use of binomial nomenclature allows for a standardized and universally recognized naming system for organisms, aiding in their classification and identification.
