First level consumer
Explanation:
First level consumers eat plants eat producers that make their own food, therefore making the mouse a first level or primary consumer.
True
Explanation:
The statement that when the distance between the balls decreases, the size of arrow increases because it shows the gravitational pull between the two balls which increases is true.
According to Newton's law of universal gravitation:
"The gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of their separation".
Mathematically, the law is written as:
F = 
F is the gravitational force
G is the universal gravitational constant
m is the mass of the body
r is the distances between them.
We see that the less the distance between the two bodies the more the gravitational force they have.

Probably C. Neutral pH doesn't affect anything, and water is polar so D isn't correct. I don't know what liquid form is, and water does form intermolecular hydrogen bonds, which creates surface tension and makes water form globules. That's how water striders can walk on water because they use the bonds and surface pressure to support them
