Answer:
Malaria can be described as a disease which is caused by a parasitic organism. The Anopheles mosquito carries the parasite Plasmodium in it. When this mosquito bites a human being, the parasite gets transferred into the blood of the person causing malaria. Before entering the blood cells, the plasmodium travel to the liver where they get matured.
Malaria is a life-threatening disease which kills many humans each year, especially people living in underdeveloped countries.
Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
Marie is experiencing the: Sympathomimetic effects (fight-or-flight state).
The sympathetic nervous system is a component of the autonomic nervous system, managing the activity of visceral organs and the automatic functions of the body, such as breathing or beating of the heart. The sympathetic nervous system is involved in many unconscious physiological activities through two neuromodulators of the catecholamine family: adrenaline, but especially norepinephrine (fight-or-flight hormones).
* It accelerates the metabolism and is activated for example in case of danger or fear, to prepare the individual to escape.
* It affects the cardiovascular system: it increases the heart rate and induces peripheral vasoconstriction, causing an increase in blood pressure.
* At the digestive level, it slows the muscular contractions of the intestines but promotes the release of glucose by the liver.
* It also has a bronchodilator effect, that is to say, it causes the increase of the diameter of the bronchi.

mitochondria are famously known as the powerhouse of the cell since it is the
one that gives the cells energy that is also used by the human being. This energy conversion is called oxidative
phosphorylation. Mitochondria are found in eukaryotic cells, including
humans. These organelles also had its
own genome, or what we called as DNA which is known as mitochondrial DNA, or
mtDNA which is present in the mitochondrial matrix. The role of mtDNA or mitochondrial DNA is to
convert the energy from food into any other forms that it thinks the cell can
use. It is containing 37 genes which are
all necessary for a normal mitochondrial function.</span>
