Answer:
by respiring and by passing urine
Explanation:
Atom is the
most basic unit of matter. They are the general term used to describe pieces of
matter. But a different kind of atom makes up an element. A combination of atom of different elements
creates a molecule. For example, you have water; it has a chemical formula of
H2O. If you separate H from O, you have two atoms. Two atoms for hydrogen and
one atom for oxygen. However, they are of different elements. And when you
combine them to form H2O, you create a molecule. Another example of molecules are air. Air pressure is gravity pulling down on air molecules. Like us,
air has also mass and the pressure is brought down by the earth’s gravity
causing an increase in weight exerted on you as you descend lower into the
atmosphere. So, as you enter into the other layers of atmosphere above the
troposphere, the air pressure starts to decrease. <span>Below the atmosphere is the
hydrosphere. This is where all liquid forms are located. And since the seawater
has a greater mass than air, it has the greatest pressure. </span>

Answer:
The correct answer would be D) In a population of herbivores, a change in the habitat provides leaves that are high up in the trees. The herbivores with longer necks can reach the leaves. They survive and reproduce. The herbivores, over time, have longer necks.
Natural selection is a gradual process which favors the survival and reproduction of organisms which have better adapted to the environment.
Adaptations or traits which favor the survival of the organisms in environment keep on passing from one generation to the next and with time theses traits get inherited in the population.
For example, in the above situation herbivores with short necks die as they could not reach the leaves that were high up in the trees. In contrast, long neck favors the survival of the organisms due to which only organisms with long necks survive and reproduce. With time, only organisms were left that had long necks.
