The plasma membrane is composed mainly of phospholipids, which consist of fatty acids and alcohol. The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer. As shown in the diagram below, each phospholipid molecule has a head and two tails.

timurjin [86]

A patient has been diagnosed with angina. As he talks with the nurse, he asks several good questions about angina and seems able to concentrate on the explanations. He seems eager to learn how to manage his condition. What assessment can be made by the nurse <u>Hardiness</u>

<h3>What is angina?</h3>

Chest pain or pressure, often known as angina or angina pectoris, is a sign of coronary heart disease and is typically brought on by insufficient blood flow to the heart muscle (myocardium).

A blockage or spasm of the arteries that feed blood to the heart muscle is typically the cause of angina. Anemia, abnormal cardiac rhythms, and heart failure are among additional factors. Atherosclerosis, a component of coronary artery disease, is the primary mechanism of coronary artery occlusion. The phrase means "a strangling feeling in the chest" and is derived from the Latin words angere ("to strangle") and pectus ("chest").

The degree of oxygen deprivation in the heart muscle and pain intensity are only weakly correlated.

A high dietary intake of protein will also increase an athlete's need for: Low glycemic foods Fluid Fat Essential amino acids
alexira [117]

When consuming high protein, it is necessary to increase the intake of water or fluids along with it.

When a high-protein diet is taken, the athlete must increase the consumption of water or fluids as the kidneys are under strain and need to work more to get rid of excess ammonia. Protein is needed by athletes to repair and strengthen their muscles. Ammonia is the bi-product of the metabolism of protein which is converted to urea and is collected by kidneys which is then removed by the body as urine. Increased levels of ammonia can lead to permanent renal damage.

How does the human capital perspective explain the differential earnings of women and men in the labor market? What are the stre
scZoUnD [109]

The human capital model suggests that wage structure plays a significant part in explaining the gender wage difference. In the event that, as suggested by the human capital model, workers of either sex earn stronger returns to experience, the pay gap between men and women will be greater.

Human capital theory's ability to assist researchers and policymakers in analyzing the connections between education and training as inputs and economic and social benefits as outputs is one of its key strengths. Due to methodological flaws including the use of a single theoretical lens, closed system modeling, inappropriate use of mathematical tools, and multi-variate analysis of interdependent variables, the human capital theory fails the test of realism.

Name different types of medicine that you can make in the woods
Talja [164]

Answer:

Explanation:

Natural Aspirin and Acne Medication

Willow bark, also known as “nature's aspirin,” contains a precursor to aspirin, which essentially provides the same benefits as the tablet. Early incarnations of aspirin were made by boiling the bark of the white willow tree.

Within the plant kingdom, trees make a substantial contribution to this figure and many species are used in traditional and modern medicine. Medicine from trees, extracted from the wood, bark, roots, leaves, flowers, fruits or seeds is fundamental to the well-being of millions of people.

Tulsi,pudina, curry leaves and aloe-vera plants are known for their medicinal uses but the coutry also home to big trees that holds special significance in Ayurveda of India. The list of famous medicinal trees in India also includes bahera tree, Albizia lebbeck, Maulsari, Indian Mahogany and Eucalyptus.

Wood contains thousands of compounds, though only a fraction of them are known to us today. Many of the compounds are linked to the tree’s defence mechanisms. They protect the tree against fungi and many other pathogens. Scientists are now investigating whether these compounds could also benefit people. For example, spruce resin protects damaged bark surface from fungal spores, and it has also been used to treat human wounds throughout the ages. Now, the efficacy of resin in wound treatment has been verified in medical research.

Xylitol is also known as birch sugar. The name reveals the origin and purpose of the compound. German and French scientists discovered xylitol as a chemical compound back in the 1890s, but it wasn’t until the 1970s when its benefits in dental health were discovered and verified by scientists in Finland.

In the early 1970s, scientists at the University of Turku discovered that xylitol prevents cavities. Some years later, researchers at the University of Oulu also found it to reduce ear infections in children. Xylitol is manufactured from birch hemicelluloses.

Antibodies for high cholesterol and cardiovascular diseases have also been discovered in wood. Pine compounds can be used to make plant sterols and stanols, which are added to margarines and yogurt products. When consumed regularly, these products can help to reduce cholesterol.

Betulin, a product of birch bark, also reduces cholesterol. Betulin gives birch bark its white colour, and it has strong antibacterial properties. The use of betulin in medicines has been researched in Finland as well as other countries including China. The betulin molecule is so large that it cannot penetrate the cell wall. Medical researchers are trying to use betulin to protect the cell surface against diseases. Betulin has been found to limit the activity of the HIV virus. The possibility of using it as an HIV drug is currently being studied.

The part of the tree branch which is inside the stem is called softwood knot. A compound called HMR lignan is harvested from the knots of spruces. It can help to prevent cancer and cardiovascular diseases. Another Finnish invention, the HMR lignan is also being studied for possible application as a HIV drug, just like betulin.

All compounds extracted from trees can be harvested at pulp plants during pulp manufacture. In future biorefineries, wood will have increasingly more diverse uses as an ingredient in a range of different products. The study and discovery of new compounds with health benefits from trees and other forest products are ongoing. In addition to the pharmaceutical industry, the cosmetics industry is also interested in products originating from wood.

(hope this helps can i plz have brainlist :D hehe)
