The positioning of the body where are major body parts are flexed is called the fetal position. In this position the back is arched forward and arms and legs are drawn closer to the torso and the head bowed. It is called this because this is the position the fetus is in as it develops in the womb.
Answer:
A protein that is destined to be secreted from the cell:
- is targeted to the RER as a soluble protein.
Explanation:
The main function of the RER is the synthesis and transport of secretion or membrane proteins.
If you are looking for the RER you could fount it on eukaryotic cells, side by side of the nucleus, and cover in ribosomes.
Answer:
Soil is a basic and fundamental natural resource, which took millions of years in its formation, resulting from the processes of disintegration and decomposition of rocks due to weathering. As much as many rocks, due to their hardness levels, seem indestructible, they all end up decomposing, even if slowly. Weathering is the general process that causes the deterioration of rocks. He is responsible for producing all the clays, all soils and dissolved substances that end up carried by rivers to the oceans. We can subdivide it into two types: chemical weathering and physical weathering. The first occurs when the minerals of a given rock undergo a chemical alteration or dissolution – and here the action of water is very important. The second occurs when there is a fragmentation of solid rock, through mechanical processes that do not change its chemical composition. Both reinforce each other. The smaller the pieces of rock created by physical weathering, the greater the surface for chemical weathering to act.
Rocks, reduced in particles through weathering, can accumulate as soil or, through erosion, be transported or deposited in the form of sediments somewhere else. Erosion is then defined as the process in which weathered materials (i.e., dismantled into smaller mineral fractions) are displaced or removed from their origin, usually by the action of water or air currents. A third geological process that should be mentioned is the dispersion of mass, which usually moves in isolated events, downhill, terrestrial materials modified or not by weathering, including large fragments of unchanged rocks.

Explanation:
Marie Curie died of aplastic anemia in 1934. Aplastic anemia is an autoimmune disease in which the body fails to produce blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. Aplastic anaemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets.
Fatigue is a symptom of aplastic anemia as the blood doesn't have the necesarry red blood cells to transport the oxygen to the organs.
Rapid heart rate happens because the body senses the decrease of oxygen's concentration and the hearts beats faster to provide the organs of oxygen.
Pale skin happens because the blood vessels are contracted in order to provide oxygen to the important organs of the body as the brain and heart. It means that less blood reaches the face and it shows as pale skin.
Prolonged bleeding from cuts happens because there aren't enough platalets to produce a blood clot to stop the bleeding.
Dizziness happens because there is not enough oxygen arriving to the brain.
If she is A negative, she can only receive blood from others A negative donors, or O- donors. This is because she has antibodies to B, and to groups that have the protein Rh (+). So she can't receive blood either B nor Rh+.
