Bicarbonate ion is important organic molecule in the buffering system of blood.
Answer:
c.Both the mass of the objects and the distance between them
Explanation:
The Law of Universal Gravitation states that the force of gravitational pull between objects is directly proportional to the product of the mass of both objects and indirectly proportional to the square of the distance between them.
This means that as the product of the masses increases, the force increases. On the other hand, as the distance between the objects increases, the force decreases.
It can be computed with the formula:
Where:
F = Gravitational force
M₁ = Mass of object 1
M₂ = Mass of object 2
r = distance between the center of the masses
G = gravitational constant (this is a fixed number so the pull is not dependent on this)
Answer:
C) Both are waves of energy, but ultraviolet waves cannot be seen.
Explanation:
Both visible light and ultraviolet are two manifestations of the same thing: electromagnetic radiation (which is, basically, energy in one of its forms). They both travel empty space as waves, but visible light has a longer wavelength, which means that the distance between succesive peaks of the wave is larger than that of ultraviolet radiation. Visible light just happens to have a wavelength in the range our eyes are capable of seeing, but ultraviolet has a shorter wavelength than that, therefore we cannot see it.
Answer:
Therapsids were "mammal-like" reptiles and are ancestors to the mammals, including humans, found today. One group of therapsids is called dicynodonts. All species of dicynodonts were herbivores (plant eaters) and their sizes ranged from small burrowers to large browsers.
Mammals evolved from a group of reptiles called the synapsids. These reptiles arose during the Pennsylvanian Period (310 to 275 million years ago). It was over millions of years that some of these therapsids would evolve many features that would later be associated with mammals.

Answer:
Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The temperature of gases is proportional to the average translational kinetic energy of atoms and molecules. The motion of individual molecules in a gas is random in magnitude and direction.
