<h2>
Through production of news cell-surface proteins with a different molecular structure by each new generation. Letter B</h2>
Explanation:
The life cycle of theses paratises extracellular alternate between the salivary glands of the insect transmitter and the blood of the mammal. During the set prior to the entry into the host, the metacylic parasites express a dense over formed by the Variant Surface of Glycoprotein, after entering to the mammal host they transform into a morphology that stays in the bloodstream.
<em>The parasites have to manipulate hosts cells in order to avoid the production of antimicrobial molecules and to benefit from growth factor production.</em>
<em>Intracellular protozoa have a remarkable adaptive capacity as they are able to resist killing by remodelling the phagosomal compartments where they reside and by interfering with the signalling pathway that leads to cellular activation. </em>
Condensation is water that collect as droplets on a cold surface when humid air is in contact with it<span />
Renin is an enzyme that helps control blood pressure and regulate levels of sodium and potassium in the body. Angiotensinogen is the hormone that causes the narrowing of blood vessels. It is released from liver to form angiotensin.
<h3>What is the role of angiotensin?</h3>
Angiotensinogen is a hormone that on hydrolysis forms angiotensin
Angiotensinogen is hydrolyzed by renin enzyme and forms angiotensin.
This angiotensin helps to increase blood pressure by the process of vasoconstriction, increased aldosterone biosynthesis and renal actions.
Thus, it can be concluded renin hydrolyzes angiotensinogen, which is released from the liver, to form angiotensin.

Answer:
D. Her walking routine
Explanation:
Carol eats 800 kilocalories a day to lose weight. She is 60 years old. Carol has been walking briskly 60 minutes daily for the past 2 months. In her younger days she lifted weights, but she has lost considerable lean body mass over the years because of inactivity. Her walking routine will increases Carol's energy output and promotes weight loss
Answer:
Explanation:
<em>Each trait of an organism is determined by discrete units called genes and individuals carry two alleles for each gene. (Mendel didn't actually discover genes though). Each gamete of an individual carries only one allele of each gene (this is Mendel's Law of Segregation).</em>
