Answer:
The correct answer is option A. "The contents of blood come into closer contact with tissues in a closed system than an open system".
Explanation:
In a closed circulatory system, the blood has an specific path, circulating from arteries to veins and to smaller blood vessels throughout the body. This is in contrast with open circulatory systems at which the blood is not contained in arteries or veins but it suffuses the body. A closed circulatory system have many advantages over open circulatory system, however in a closed circulatory system the contents of blood are not into closer contact with tissues in than an open system. Actually, in an open circulatory system the blood is in closer contact with tissues.

Answer:
B) Natural selection favored rabbits that were resistant to the virus
Explanation:
Most likely, virus resistance occurred over time, as a consequence of mutation. Individuals that carried the resistance mutation become favourable by natural selection.
Natural selection is evolutionary mechanism which favours traits of an organism that help him survive and reproduce (increase organism's fitness). In the example above, resistant rabbits that survived had the favorable trait (resistance) by natural selection.
Your answer would be D. The possible combinations of alleles in offspring based on the parents genetic makeup. The punnet square is basically used to determine what the outcome of an offspring would be.
Answer:
3) The correct answer would be the third option.
Enzymes are biocatalysts which increases the rate of a biochemical reaction is decreasing the activation energy required by the reaction.
The substrate binds to the active site of the enzyme to form an enzyme-substrate complex. It is then converted to enzyme-product complex. Lastly, the product is released and the enzyme is ready for a new cycle of reaction.
4) The correct answer would be cohesion.
Cohesion or cohesive force refers to the attractive force by which like-molecules are stick together.
For example, water molecules are stick together to form droplets.
