Answer:
For the eggs to survive and have a chance of hatching, sea turtles must lay their eggs on sandy beaches. As they are developing, the embryos breathe air through a membrane in the eggs, and so they cannot survive if they are continuously covered with water.
Explanation:
Answer: Adaptations to a common environment and examples of convergent evolution.
Explanation:
Ichthyosaurs were the giant marine reptiles but it possess tails and dorsal fins though this is not a common character of reptiles. But the presence tails and dorsal fins states that it was an adaptation which was required at that time.
This giant reptile was an mixture of modern fish and dophins. It also had dorsal fin for swimming in water and has vertical tail which was used for the propulsive stroke. They were air breathing but had some part of their life in water as well like other reptiles.
Convergent evolution can be defined as the evolution of similar features in the species found at different period.
Some of the fishes like dolphins and other fishes shows convergent evolution to ichthyosaurs.
The are formed by cells building carbohydrates polymers, they use energy
to form glycosidic linkages..the bonds between monosaccarides...which
is made by joining two specific monomers, glucose and fructose.
The right answer is A) Starches
