lapo4ka [179]

Answer:

<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>

kompoz [17]

Answer:

Producer

Explanation:

Plants are producers. They make their own food, which creates energy for them to grow, reproduce and survive. Being able to make their own food makes them unique; they are the only living things on Earth that can make their own source of food energy. Consumers need plants to turn solar energy into chemical energy for us to use; or in this case, the trout.

is it right thats what the question means?

answer in eng: The sympathetic division initiates the fight-or-flight response and the parasympathetic initiates the rest-and-digest or feed-and-breed responses. The sympathetic and parasympathetic nervous systems are important for modulating many vital functions, including respiration and cardiac contractility.

answer in polish: Podział współczujący inicjuje reakcję walki lub ucieczki, a przywspółczulny inicjuje reakcje odpoczynku i trawienia lub karmienia i rozmnażania. Współczulny i przywspółczulny układ nerwowy jest ważny dla modulowania wielu funkcji życiowych, w tym oddychania i kurczliwości serca.

stepladder [879]

Answer:

loss of genetic diversity  

Explanation:

Artificial selection, also known as selective breeding, refers to the identification by humans of desirable phenotypic features (traits) in plants and animals and the subsequent breeding procedures to enhance and perpetuate these traits in offspring. As a consequence of artificial selection, future generations of selectively bred animals/plants will share favorable gene variants (alleles), thereby genetic diversity will decrease in the population. This reduction in the gene pool will affect genetic progress and consequently also breeding programs in the future.
