How do these functions compare between single-celled and multi-celled organisms?
A.
Single-celled organisms must perform all of these functions with one cell, while multi-celled organisms can have specialized cells for different functions.
B.
Single-celled organisms can perform only some of these functions, while multi-celled organisms can perform all of these functions.
C.
Single-celled organisms can perform all of these functions, while multi-celled organisms can perform only some of these functions.
D.
Neither single-celled organisms nor multi-celled organisms can perform all of these necessary functions.

A50.0g sample of liquid water at 0.0 c ends up as ice at -20.0 c. how much energy is involved in this change?

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
