The correct answer is option C, Chromosome

Explanation:

What is another expression for the speed of an object

Answers

Velocity also expresses the speed of an object.
Hi the answer to your question is Escape Velocity In physics, escape velocity is the minimum speed needed for an object to "break free" from the gravitational attraction of a massive body.  More particularly, escape velocity is the speed at which the sum of an object's kinetic energy and its gravitational potential energy is equal to zero.

Which term best describes the expression 137 rabbits per km2?a. exponential
b. density
c. biome
d. size

Answers

b. density

Km^2 (kilometers squared) is an area of land, so 137 rabbits per km^2 describes the density of rabbits in a given area

Km^2 does have an exponent, but "exponential" has nothing to do with 137 rabbits. A biome is a type of landscape, merely knowing the density of rabbits would not tell the biome. This expression counts the number of rabbits within an area, not just the size of rabbits or size of land area.

Answer: The answer is b. density

Explanation: I took the test off of k12 and it was correct.
