3 0

When humans improperly dispose of equipment like refrigerators than have CFC and HCFCs, when they are subjected to UV light from the sun, they decompose to release Cl- radicals (CFCl3  CFCl2+ + Cl-). When the CL- are released into the atmosphere, they reach the stratosphere and react with the ozone. The Ozone is reduced from O3 to O2;

Cl + O3 -- ClO + O2

ClO + O - Cl + O2

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>

galben [10]

Answer:

Option E

Explanation:

Correlation and causation studies are two different things. Co-relation is a simple representation of relationship between two subjects A and B. It does not mean that A will be caused because of B or B will be caused because of A.

However, causation connects two variables “cause and effect.” The case of negative impacts produced by TV during childhood stage is more a cause and effect relationship than a co-relation

Hence, option E is right answer
