1. Both objects have mass and therefore have a gravitational force.
2. Lower mass objects have less gravitational force.
3. Higher mass objects have stronger gravitational force.
Explanation:
To solve this problem, we need a recap of the newton's law of universal gravitation:
The law states that "the gravitational force of attraction between two object is directly proportional to the product of their masses and inversely proportional to the square of the distances between them."
F = ![\frac{G[tex]m_{1} m_{2}](https://tex.z-dn.net/?f=%5Cfrac%7BG%5Btex%5Dm_%7B1%7D%20m_%7B2%7D)
}{
}[/tex]
G = universal gravitational constant
m₁ = mass of object 1
m₂ = mass of object 2
r² = distances between the two masses
From this we can infer that, for gravitational force to exists, both objects must have mass.
Since mass is directly proportional the gravitational force, the lower the mass the less the gravitational force and the higher the mass the stronger the gravitational force.

D, because both A and C are correct.
A blood hemoglobin measurement of 13.5 g/100 ml would be a normal level of measurement.
Hemoglobin is a protein in red blood cells that transports oxygen. How much hemoglobin is in your blood is determined by the haemoglobin test? The most significant part of red blood cells is hemoglobin. It is made up of heme, a protein that binds oxygen. Adults typically achieve a range of outcomes, but in general: Male: 138–172 grams per liter (g/L) or 13.8–17.2 grams per deciliter (g/dL). Women: 121–151 g/L or 12.1–15.1 g/dL. The nominal level of measurement is the first measurement level. The variables' numbers are only used to categorize the data at this level of measurement. Words, characters, and alphanumeric symbols can all be employed at this level of measurement.

The correct option is this: VARIATIONS ARE GREATER OVER LAND THAN OVER WATER.
Temperature variation over water is very small compared to temperature variation over land. This is because, water has high specific heat capacity, which enables it to resist temperature changes when it absorb heat or when it releases heat. A large amount of heat has to be lost or gained before water will show a one degree Celsius temperature change.
The sponge-like structure, as well as the high salt content of water and the <span>ease of contaminating water contribute to the environmental stress on a coral reef.
