Answer: Malaria is a disease caused by parasite Plasmodium malariae which enters the body through the bite from the anopheles mosquito. This parasite is present in the saliva of the anopheles mosquito and enters the bloodstream when the mosquito takes a blood meal. Plasmodium's reservoir is human and intermittent host ia anopheles mosquito.
Explanation:
Malaria can be caused by five different species of Plasmodium.
PORTAL OF ENTRY AND MODE OF TRANSMISSION: Malaria is always transmitted by the bite of a female Anopheles mosquito infected by plasmodium. Transfusion of blood from one infected person to another and use of contaminated needles and syringes are other potential modes of transmission. Congenital transmission of malaria can also occur. When the parasite enters the blood via the saliva of the mosquito it multiplies in the blood and enters the liver and infects the person who present symptoms of malaria as chills fever headcahe joint pain. Humans are the reservoir for the plasmodium species causing malaria.
Digestion
The difficult process of digesting food into nutrients that the body utilizes for energy, development, and cell repair is known as digestion. Along with producing trash to be expelled, digestion also produces garbage.
The digestive system, also known as the gastrointestinal tract, is a long, twisted tube that extends from the mouth to the anus. It is made up of several muscles that control the transport of food and added cells that make hormones and enzymes to help break down food. Other "accessory" organs like the liver and pancreas are also necessary for digestion along the route.
To be taken into the watery blood plasma, big, insoluble food molecules must be broken down into smaller, water-soluble food molecules during digestion.

Answer: TRUE
Explanation: Myelin is a thick layer of lipoproteins that "wraps" the axons of some nervous cells in a discontinuous form. In electric terms, MYELIN, reduces the membrane capacitance because this layer is to thick to allow the action potential of the entire axon, to depolarize a complete nervous cell.
That is why there are some structures called <em>Ranvier Nodes, </em>those are spaces between every "wrap" of mielina, that have voltage sensitive sodium channels. This space between myelin sheaths, allows a "saltatory nerve conduction", that transmit the electrical impulse from one <em>Ranvier Node </em>to another, becoming the transmition in one of the fastest in the body. If this system would not exist, then the nervous transmision would be very slow.
