Answer:
b. It allows gas exchange while preventing water loss
Explanation:
Amniotic eggs are the feature of land animals such as reptiles, birds, mammals, etc. The amniotic eggs have four extra-embryonic membranes. This semipermeable protective shell allows the exchange of respiratory gases but does not support the transport of water out of the egg.
The ability to maintain the water inside the egg while permitting gaseous exchange is the specific feature of amniotic eggs and allowed diversification of land animals in the land habitats.
Answer:
It contains the least amount of energy.
Explanation:
As compared to the bottom level, the energy of the top level is less in amount. Here is given an energy pyramid, in which the top level has the lowest energy and the bottom level has the most energy.
Answer: Option C.
Enzymes lowers activation energy required for a given reaction.
Explanation:
Enzymes are biological catalysts that are produced by living organisms which speed up the rate of chemical reaction.
Enzymes lower the activation energy of a given reactions. As the activation energy is lowered, the reaction becomes faster. Enzymes speed up the rate of reaction by lowering the activation energy.
