Prior to cell division, the DNA material in the original cell must be duplicated. Why is this important?

DNA has to duplicate itself prior to cell division, so that the 2 daughter cells that will be created during cell division will have the same DNA identical to the parent cells.

The human immunodeficiency virus (hiv) that causes the disease known as aids selectively infects ________ cells.
Furkat [3]

The human immunodeficiency virus (HIV) that causes the disease known as aids selectively infects helper T cells (CD4+).

This retrovirus also infects macrophages and dendritic cells. When CD4+ T cell numbers decrease below a critical level (due to the killing of this cells with different mechanisms), cell-mediated immunity is lost. As a result, the body becomes progressively more susceptible to infections, leading to the development of AIDS.

<span> HIV can be transmitted only via body fluids like blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk, which means that people usually get or transmit HIV through sexual behaviours and use of the needle. For HIV infection, these fluids must come in direct contact with a mucous membrane or damaged tissue. Another way is to be directly injected into the bloodstream (from a needle for example).</span>

The femur is a typical example of a long bone. Describe the structure of the femur diaphysis and the epiphyseal ends. Explain wh
dimaraw [331]

<u>Answer</u>:

Femur diaphysis and epiphyseal ends is made up with cortical bone and contains bone narrow. It is in the middle tabular part and composed with compact bone and central marrow cavity is situated around it. It is round in shape and a long bone. It is the origin of the attachment of many muscles as well as ligament.

The femur is the longest bone which is present in our thigh and also call as thigh bone. The division of femur can be divided into shaft, proximal and distal. In some aspect it is the strongest bone of our body and it helps in any activities.

Greenhouse gases are measured by their ability to trap outgoing solar radiation and convert it to heat, warming the atmosphere.
Gnom [1K]

Answer:

Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.

Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.

This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.

Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.
