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.

Marina86 [1]

Explanation:

Natural selection is the mechanism that is responsible for the evolution of organisms.  

In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.  

The <em>C. cantonensis </em>is brighter in color whereas the <em>C. multidentata</em> is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore <em>C. cantonensis</em> is more susceptible. The mottled drab species is not easily predated by the species.  

The 30 % offsprings of <em>C. cantonensis</em> can survive till the reproductive age  whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.

The species with mottled drab color is the result of the differential reproductive rate.

Why is it difficult for persons to survive on planet mercury?
aliya0001 [1]
Mercury is a barren planet with little atmosphere. In many regards it is similar to our own moon. However, it is also very close to the Sun, so humans will have to set up bases in craters or near the Poles to avoid being blinded.
