Answer:
If the substance will enter the cell by diffusion, the temperature will not change raise inside the cell as the water have high capacity of with standing the temperature changes. Hence water is called as thermal insulator.

The hind legs of the frog are adapted for leaping and swimming. They have strong extensor muscles. When these muscles contract, the limbs extend thrusting the foot against the water or land. The frog's forelimbs are shorter and used to steer the frog while swimming and to absorb shock while landing.
Answer:
Mimicry
Explanation:
In mimicry, species evolve to resemble other species; in Müllerian mimicry this is a mutually beneficial co-evolution as each of a group of strongly defended species (such as wasps able to sting) come to advertise their defences in the same way. Features evolved for one purpose may be co-opted for a different one, as when the insulating feathers of dinosaurs were co-opted for bird flight.
Adaptation is related to biological fitness, which governs the rate of evolution as measured by change in gene frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the other species, such as with flowering plants and pollinating insects.
Answer:
1. vi. Preganglionic
2. vii. adrenergic
3. ii. sympathetic chain ganglia
4. iii. Craniosacral
5. viii. splanchnic
Explanation:
Action potential travel down preganglionic nerve fibre. They travel towards Vagus Nerve near the effector organ. These impulses arrive at cardiac plexus, which create action potential in postganlianic.
