Answer: High-pressure systems are frequently associated with light winds at the surface and subsidence through the lower portion of the troposphere. In general, subsidence will dry out an air mass by adiabatic or compressional heating. Thus, high pressure typically brings clear skies.
Explanation:
(1) Is referring to Newton's first law, an external force (gravitational force) is applied to frogs motion, thus causing it to deviate from a straight line
(2) is referring to Newton's third law of motion, the action force is done by the ball hitting the ground and the direction is downwards, the reaction force is done by the ground transferring that same force to the ball, acting upwards
(3) I think it's also the first law, the person on a train is showing, the force to keep it at rest, the sudden halt of the train causes a reaction force to act on the person, does making the person move
(4) I think it's both Newton's second law and third law motion.

Natural selection is a process by which organisms that are better adapted to their environment tend to D-survive.
Rationale behind not choosing other options:
A. Better adaptation to an environment doesn't lead to an increase in the size of the organisms. The organisms rather become sturdy and efficient at perform optimally as per the requirement in the environment for their survival.
B. Migration takes place to minimize competition for food, shelter, and space in an environment or a habitat.
C. Organisms that evolve new traits tend to better survive in an environment and natural selection favors such organisms over the inefficient ones.
Answer:
This unique head shape has been termed the cephalofoil in recognition of its wing-like appearance. ... Some suggest the cephalofoil acts like a canard to provide hydrodynamic lift and increase maneuvering capabilities. Another hypothesis is that the cephalofoil functions in prey manipulation.
Explanation:
I think the answer is Evolution.
