Explanation:

A relatively important aspect of human biology is genetics.

Genetics is very important in public health, lifestyle, environment, and treatment of medical conditions. Therefore, it is important to lead a healthy life such as exercise, a healthy diet, and mental health to maintain physical and mental health.

The environment also influences this aspect. A healthy and pollution-free environment keeps people healthy and prevents the transmission of diseases such as respiratory diseases and infectious diseases caused by such pollution.

The provision of medical services is also important for maintaining the health of the population. Proper medical treatment in case of illness is very important to restore the health of the population.

The health field concept:

According to the “Health field” concept. There are four major determinants of health or ill health.

A. Human Biology

Every Human being is made of genes. In addition, there are factors, which are genetically transmitted from parents to offspring. As a result, there is a chance of transferring defective trait. The modern medicine does not have a significant role in these cases.

a. Genetic Counselling: For instance during marriage parents could be made aware of their genetic component in order to overcome some risks that could arise.

b. Genetic Engineering: may have a role in cases like Breast cancer.

B. Environment: is all that which is external to the individual human host. Those are factors outside the human body. Environmental factors that could influence health include:

a. Life support, food, water, air etc.

b. Physical factors, climate, Rain fall

c. Biological factors: microorganisms, toxins, Biological waste,

d. Psycho-social and economic e.g. Crowding, income level, access to health care

e. Chemical factors: industrial wastes, agricultural wastes, air pollution, etc

C. Life style (Behaviour): is an action that has a specific frequency, duration, and purpose, whether conscious or unconscious. It is associated with practice. It is what we do and how we act. Recently life style by itself received an increased amount of attention as a major determinant of health. Life style of individuals affects their health directly or indirectly. For example: Cigarette smoking, unsafe sexual practice and eating contaminated food

D. Health care organisation

Health care organisations in terms of their resource in human power, equipment, money and so on determine the health of people. It is concerned with;

a. Availability of health service: People living in areas where there is no access to health service are affected by health problems and have lower health status than those with accessible health services.

b. Scarcity of Health Services leads to inefficient health service and resulting in poor quality of health status of people.

c. Acceptability of the service by the community

d. Accessibility: in terms of physical distance, finance etc.

e. Quality of care that mainly focuses on the comprehensiveness, continuity and integration of the health care.

To activate the myofiber, neurons must pass through the endomysium structure.

The impulse travels from the T-TUBULES to the SARCOPLASMIC RETICULUM. 3. The membrane's calcium gates in the Sarcoplasmic Reticulum (SR) open as the impulse passes through it. CALCIUM therefore diffuses between the myofilaments and outside the SR as a result.

An electrical impulse (action potential) in cardiac and smooth muscle cells causes calcium ions to enter the cell through an L-type calcium channel positioned in the cell membrane (smooth muscle) or T-tubule membrane (cardiac muscle).

Ferns are beneficial to their ecosystem because they help promote rock weathering and prevent soil erosion.

They do this by absorbing water and nutrients from the soil, which helps to break down rocks and keep the soil in place. This is beneficial because it helps to keep the ecosystem healthy and balanced.

Ferns are a type of plant that is known to be very effective at promoting rock weathering, while also preventing soil erosion. One of the ways that ferns promote rock weathering is through their root systems. Ferns have a very dense root system that is very effective at breaking up rocks and promoting the weathering process. In addition, ferns also release a variety of acids and chemicals from their leaves that can help to break down rocks.

Ferns are also very effective at preventing soil erosion. This is because their root systems help to hold soils in place, while their leaves help to trap water and prevent it from running off. In addition, the dense canopy of a fern can help to protect the soil from the sun and wind, which can further help to prevent erosion.

The main characteristic of T cell tolerance is that if the self antigens are from the same tissue or are presented by the same antigen-presenting cell, regulatory cells can suppress autoreactive lymphocytes that identify a variety of distinct self antigens.

The immune system's capacity for self-tolerance is its capacity to see its own antigens as non-threats while appropriately mounting an attack against alien substances. Normal physiological function and general health depend on this equilibrium of immune defense and self-tolerance.

T-helper cells exhibit the surface receptor known as the T cell receptor, which is made up of a polypeptide heterodimer (marked, for example,α/β). T helper cells are able to identify viral peptides in conjunction with class II MHC proteins, which are typically found on an antigen-presenting cell's surface (APC).

In a human ovary, an oocyte is supported by follicular cells and the product formed by the primary oocyte after the first meiotic division is the secondary oocyte.

Oogenesis is the process through which an ovum (egg cell) differentiates into a cell capable of developing further when fertilised. It grows through maturation from the original oocyte. The embryonic stage is when oogenesis begins. Oocytogenesis, the conversion of oogonia into primary oocytes, is the first step in the process of generating primary oocytes, which is the beginning of oogenesis. Only one mature oocyte and three additional cells known as polar bodies will emerge from a single oogonium. Before or soon after conception, oocytogenesis is finished.

The first meiotic division begins before the female foetus is delivered and is finished in the tertiary follicle of the ovary. When a sperm and an ovum fuse, the secondary oocyte's meiotic division is finished. The secondary oocyte starts the second meiotic division but then arrests once more. If a sperm fertilises it, it will finish the division, producing a mature ovum and another polar body.

Yes, farming/ranching (growing animals) produce more air pollution than all transportation (cars, planes, etc..)

When the environmental impact of their feed is taken into consideration, cows, pigs, and other farm animals in Europe produce more greenhouse gases annually than all of the cars and vans in the continent combined, according to a new analysis by Greenpeace. However, while governments have focused their climate policy on renewable energy and transportation, efforts to lessen the impact of food and farming on the climate have lagged. This is because of the increase in meat and dairy products in Europe over the past ten years.

Livestock on EU farms (including the UK) was responsible for the equivalent of around 502 million tonnes of carbon dioxide annually in 2018, the most recent year for which precise data is available from the UN Food and Agriculture Organization. This carbon dioxide was primarily released as methane. In contrast, 656 million tons of carbon dioxide were produced by European vehicles and vans in the same period.

The overall annual emissions are equal to 704 million tonnes of carbon dioxide when the indirect greenhouse gas emissions are considered. This is done by estimating the deforestation and land use changes related to the production of animal feed. Between 2007 and 2018, the EU's output of meat and dairy increased by 9.5%, which, according to Greenpeace, resulted in an increase in emissions of 6% annually, or nearly 39 million tons. This would be the same as adding 8.4 million new cars to the road.

Amino acids are the chemicals that have been created in studies comparable to those carried out by Miller and Urey.

Harold C. Urey and Stanley L. Miller conducted an experiment to explain the beginning of life on Earth. They thought that the inorganic minerals that made up the early earth's environment may have created amino acids. They used the gases that the two biologists' thought were in the early earth's atmosphere: methane, water, hydrogen, and ammonia. The chemicals were cycled inside the system in sterile glass flasks and tubes that were connected in a loop.

The experiment fell short of explaining how proteins were in charge of creating amino acids. Some scientists disagree, claiming that the gases utilised by Miller and Urey are not as plentiful as the experiment indicates.

A fruit is a mature, ripened ovary along with its contents. The ovary is the reproductive structure in the plant flower that contains the ovules. From the earliest stages of flower development until the ovules become fertilized and turn into seeds, the ovary encloses and protects the ovules.

Fruits are high in dietary fiber, vitamins (particularly vitamin C), and antioxidants. Although fresh fruits spoil quickly, their shelf life can be extended by refrigerating them or removing oxygen from their storage or packaging containers.

Fruits can be juiced, jammed, and jellied, and then preserved through dehydration, canning, fermentation, and pickling.
