HIV is the human immunodeficiency virus. Causer of AIDS, it attacks the immune system, responsible for defending the body from diseases. The most affected cells are CD4+ T lymphocytes. And it is by altering the DNA of that cell that HIV makes copies of itself.

<h3>1. Discuss the pathophysiology of HIV in relation to the reduction of CD4 cells</h3>

HIV binds to a component of that cell's membrane, CD4, penetrating its interior to multiply. As a result, the defense system gradually loses the ability to respond properly, making the body more vulnerable to disease.

<h3>2. Discuss the body's immune response to the virus (HIV)</h3>

The innate immune responses to HIV infection are mainly the intense production of cytokines, such as interleukin (IL)-1 and interferon (IFN)-1, and the activation of natural killer (NK) cells, which can temporarily control HIV replication. through apoptosis of infected cells

<h3>3. Explain the molecular and cellular immune response that leads to the swollen lesion.</h3>

due to the accumulation of primary immune cells and the body's long attempt to fight the infection

<h3>4. Discuss the cellular and molecular immune response that results in enlargement of the spleen and cervical lymph nodes</h3>

An infection from bacteria and viruses, including HIV, can cause swelling of the lymph nodes. The swelling occurs because the infection reaches the nodes through lymph fluid. HIV most often affects lymph nodes around the neck as well as in the armpits and groin.

Explain why increased ecosystem diversity contribute to increased biodiversity in the biosphere
Leto [7]

Answer: Diversity, referring to the state of having many different organisms cohabitate within an area is a desirable outcome for many ecosystems. The presence of a wide spectrum of different organisms allows for more life to be able to thrive in an ecosystem. For example, an ecosystem with a wide array of shrubs, grasslands and forested areas is able to accommodate more life forms than an ecosystem of just forest. This increased capacity to support life directly improves the capacity of the biosphere to support life as well, diversity leading to growth.

The​ half-life of​ carbon-14 is 5600 years. If a piece of charcoal made from the wood of a tree shows only ​% of the​ carbon-14
Leokris [45]

Mature and established trees die for a combination of reasons but sudden browning of foliage is typically associated with a lack of water supply to the canopy. Water supply can be cut off to the canopy due to obvious issues including deficiency or root damage.

<h3>What is Carbon?</h3>
  • Carbon is a chemical component with the symbol C and atomic number It is nonmetallic and tetravalent—its atom makes four electrons unrestricted to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon produces up only about 0.025 percent of Earth's crust.
  • Carbon is employed in some way in almost every industry around the globe. It is used for fuel in the form of coal, methane gas, and crude oil (which is used to produce gasoline). It is used to make all sorts of fabrics including plastics and alloys such as steel (a mixture of carbon and iron).
  • Carbon is a chemical element with the symbol C and atomic number 6. Categorized as a nonmetal, Carbon is a solid at room temperature.
