Answer: Altricial young are born helpless and require care for a length of time. Altricial birds include herons, hawks, woodpeckers, owls, cuckoos and most passerines. For example, with ground-nesting birds such as ducks or turkeys, the young are ready to leave the nest in one or two days.
Explanation:
Hot air always rises from the equator. As this air climbs higher in the sky, it cools. Cool air can hold less water than warm air. This means that as the air cools, clouds form that release most of the water they hold. Because the cooling air is above the equator, the moisture rains back down on the tropics.
The right option is; scientific laws were theories that have been tested, proven, and adopted as laws
.
Scientific laws are generalized rules that are created to describe a body of observations in the form of words or mathematical equations. Scientific laws are based on repeated experimental evidence that have been tested, proven, and they are commonly restricted to a specific set of conditions. Examples of scientific laws are Newton's law of gravity and the Hubble's law of cosmic expansion.
