HIV is spread during unprotected sex or through contact with infected blood; it cannot be cured, but early treatment can minimize the long-term consequences.
HIV is transmitted through contact with infected bodily fluids; there is no cure or safe treatment to reduce the symptoms and consequences of the disease.
HIV is transmitted by sharing drug needles or food with an infected individual; it cannot be cured, but there are experimental medications to minimize the risk of AIDS.
I believe the correct answer is: HIV is spread during unprotected sex or through contact with infected blood; it cannot be cured, but early treatment can minimize the long-term consequences.
Human Immunodeficiency Virus is a type of virus which causes an impairment of the immune system of the person making them susceptible to diseases such as tuberculosis, influenza and any other disease that can exploit this opportunity. It is spread by a person coming into direct contact with infected bodily fluids such as saliva during deep kissing, semen during intercourse, blood after an accident or even fluids when sharing needles and syringes for drug addicts. There is no cure but the current form of treatment slows down the virus to prevent some consequences.
The virus is enters the body through open wounds or surfaces such as the vagina or mouth where the skin is very thin and can tear. After penetrating the skin, it attaches to specific immune cells called CD8+ T-cells on points called receptors. It then enters the cell and replicates itself in the nucleus of the cell and as it goes out, it kills these immune cells making the person to have a weak immune system. The current drugs used called AntiRetroVirals (ARVs) such as the drug Zidovudin stops the virus from replicating thus reducing the total amount of virus in the body called the Viral Load. Some drugs target enzymes called proteases and reverse transcriptase that help the virus to replicate. This viral load is what is counted to estimate the total volume of HIV someone has in their body. Infected persons should use protection while having sex and also avoid sharing sharp objects to prevent transmission. They also need to take their medication to make them much more healthier in addition to taking proper balanced diets.

The HIV is spread in unprotected sex or through contact with an infected blood. Although it cannot be cured but still the early treatment can reduce the long term consequences.
Further Explanation:
HIV or the Human Immunodeficiency Virus reduces the person's immune system by destroying or damaging the cells which fights with disease and infection. Proper cure for HIV is not there but effective medical care can control it.
There can be different stages of HIV:
1. Stage 1: Acute HIV infection: In acute HIV infection there is high number of virus in the blood and they are very contagious.
2. Stage 2: Clinical latency: It is chronic HIV infection. At this stage, HIV is active however reproduces at a low levels.
3. Stage 3: Acquired immunodeficiency syndrome: It is very critical stage of HIV infection. Symptoms of AIDS include chills, swollen lymph glands, sweats and weight loss.
Transmission of HIV:
1. Through sexual behavior or by the use needle or syringe. Example certain fluids like blood, rectal fluids, breast milk and pre-seminal fluid.
2. From the mother to child during breast feeding, pregnancy or birth.
3. Receiving blood through the transfusions or the organ transplants
4. Contact through the wounds, skin or broken skin and an infected blood.
HIV can also be converted into HIV superinfection, it occurs when a person with HIV gets infected with another strain of virus. The new strain may live along with the original strain or may replace the old strain. The superinfection can cause people to become sicker faster.

The correct answer is 50.
Proteins are complex biomolecules made out of amino-acids bound together with peptide bonds. They can be comprised out of thousands of several polypeptide chains with thousands of amino-acids organised in complex structures. But, some of them can contain only around 50 amino-acid and still posses all of the complex traits of an protein.
Some polypeptides contain only 3 amino-acids, but technically they are not classified as proteins due to a big functional and structural differences between a simple polypeptide chain and a protein. Proteins are made out polypeptide chains, but this is only the primary structure of an protein. the polypeptide chains in a protein are organized into complex 3D structures that give them novel traits and complexity as compared to plain polypeptide chains.
Answer: 50
Explanation:-
Proteins are polymers which are very critical for the normal functioning of the human body. They are essential for the structure, function, and regulation of the body’s tissues and organs.
Proteins are made up of number of smaller units called amino acids that are attached to one another by peptide bonds and thus form a long chain of polymer called as protein.
A protein at least 40 amino amino joined together by peptide bond is known as protein.
B. cholesterol.
C. lipids.
D. amino acids.
The oldest layers are on the bottom, and the youngest layers are on the top.
B. The distribution of sunlight.
C. The oceans' currents.
D. The prevailing winds.
The Earth has three main climate zones because of the differences in latitude and the distribution of sunlight.
Climate is the average weather conditions in an area for over a long period. Three major climate zones on Earth are:
1. Polar zone
The characteristic of this polar climate is cool summer and long extremely cold winter. The polar climate has a freezing climate and most of the time below zero degrees. The farther north of Canada, Europe, and Russia are the area that categorizes in this polar zone.
2. Temperate zone
The temperate climate zone lying between 23.5 degrees and 66.5 degrees north and south latitudes. Temperate climate zones experience warm to hot summers and cool winters, with the greatest temperature variations throughout the year.
3. Tropical zone
The regions between the equator and the tropics are tropical zone. In this zone, the temperature is warm, has the most rain and little temperature variation. The climate is hotter here because the Sun’s light is directly overhead at the equator. An area in this zone has lush plants and trees and varied animals.

Proteins and complex carbohydrates are part of the four major macromolecular groups and play crucial roles in our body functions and energy provision. They are essential in our diet, assisting in maintaining connective tissue, aiding blood clotting, and providing energy for our bodies.
Proteins and complex carbohydrates are both part of the four major macromolecular groups, which also involve lipids and nucleic acids. These macromolecules are vital to the human diet, providing fuel for the body, and undergo digestion and energy production processes. Carbohydrates can be both complex, like starch and glycogen or simple sugars like glucose and fructose. These sugars are key contributions to ATP production in cells, and glucose specifically, is controlled by a variety of endocrine mechanisms to regulate its presence in the bloodstream. The excess glucose is stored as glycogen in the liver and skeletal muscles, or instead transformed into fat in adipocytes.
Proteins along with carbohydrates are also essential in the maintenance of connective tissue and assisting in blood clotting. This prominence of these macromolecules in the diet is why athletes often 'carb-load' before engaging in major competitions, allowing their bodies to possess enough energy to compete at such high levels. Foods like grains, fruits, and vegetables are all natural carbohydrate sources, providing us with the glucose our bodies require. Therefore, proteins and complex carbohydrates showcase inherent essentiality within the human diet, playing significant roles in body function and providing necessary energy for activities.
