How would you describe the relationship that gravity has with mass and distance.
PSYCHO15rus [73]

Answer:

Mass does not affect gravity and distance has an indirect relationship.

Explanation:

The equation for gravity is, g = \frac{GM}{R^{2} }

where, G = gravitational constant

             M = mass of the planet

             R = distance between the bodies (object and center of planet)

so, gravity depends on the mass of planet,  not on mass of object

 and is inversely proportional to sqaure of distance.

liq [111]

He or she is said to be in a positive nitrogen balance state.

Nitrogen balance is the traditional method of determining dietary protein requirements. Determining dietary protein requirements using nitrogen balance requires that all nitrogen inputs and losses are carefully collected, to ensure that all nitrogen exchange is accounted for. Positive nitrogen balance is associated with periods of growth, hypothyroidism, tissue repair, and pregnancy. This means that the intake of nitrogen into the body is greater than the loss of nitrogen from the body, so there is an increase in the total body pool of protein.

timurjin [86]

Answer: The statement is false

Explanation:

NONSENSE mutation, NOT MISSENSE mutation causes premature chain (protein) termination.

Missense mutation is simply a kind of point mutation where a single nucleotide is changed to cause substitution of a different amino acid, thus resulting in a non-functional protein.

So, non-functional protein is caused by missense mutation making the statement false

There is a scientific consensus that life exists on other planets

and

The scientists only studied one meteorite

The first one because the other ones don't make sense, and because it is a scientific consensus. The latter because they only studied one, and imagine if they studied other ones...
