Answer:
The correct answer will be option- is characterized by exaggerated vasoconstriction in the extremities
Explanation:
Raynaud's disease is the condition caused when the blood vessels react in an exaggerated way to the emotional or cold stress.
The condition occurs to maintain the temperature of the body in the normal range as in cold conditions the blood vessels constrict to maintain the warmth of the body inside the heart, brain and the vital organs.
The blood vessels undergo vasospastic attack by blocking the flow of blood causing the skin to turn red, blue or white.
Thus, the selected option is the correct answer.
Enzymes and acidic juices in the stomach, which break proteins down into smaller molecules, is known as proteolytic enzyme.
Proteolytic enzyme (also known as protease) is any group of enzymes that break down the long chainlike proteins molecules into smaller molecules (peptides) and later into amino acids. In the stomach, protein digestion takes place. The three main proteolytic enzymes; pepsin (produced by the stomach), and trypsin and chymotrypsin (produced by the pancreas) breaks down proteins into polypeptides which are eventually broken down into amino acids by several exopeptidases and dipeptidases.
The air that we breathe is mostly made up of nitrogen (78%). 21% is oxygen which is needed for animals and humans in respiration and 0.03% is carbon dioxide which is needed for plants to make energy in a process called photosynthesis. The bit that is left is made up of rare gases like helium and argon and methane.
Answer:
Convergent plates collide causing earthquakes and volcanoes, and creating mountains.
Therefore second answer, The plates move towards each other at these boundaries and the more dense plate will sink under the less dense plate into the mantle where it is destroyed. (This creates a trench.)
Explanation:
In the lithosphere the plates melt when they go down.
!!!
Remember:
Convergent = Collide
Divergent = Divide
Transform = Slide
