Answer:
THERE IS A SYSTEM OF BODY CALLED THE EXECTORY SYSTEM
Explanation:
The organs of this system get rid of a certain waste. The skin gets rid of sweat. The lungs get rid of carbon dioxide and water vapor. The liver gets rid of bile, which, in addition to breaking down fats, is partially made up of the breakdown of red blood cells. The kidneys get rid of toxins from the blood. The large intestine gets rid of undigested food. in this way the Dermal, Respiratory, Lymphatic, Urinary, and Digestive Systems work together to get rid of wastes.
Answer:
The way they sound. like the way they type if that makes sense
Answer:
The correct answer is 327.78.
Explanation:
A mortality rate refers to the determination of the rate of the occurrences of deaths in a given population in the course of a particular time period. The formula for finding the mortality rate is:
Deaths taking place in a given time duration / the size of the populace among which the deaths have taken place × 10ⁿ
The given population of the country is 250 million
The number of individuals died due to a certain disease is 819450
Thus, the mortality rate per 100000 can be calculated as:
819450 / 250000000 × 100000 = 327.78 deaths per 100,000 people.
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>
