The film defines species as populations whose members don't interbreed. what keeps different galápagos finch species from mating

abruzzese [7]

Galapagos species are among those populations whose members do not interbreed. The reasons that keep them from mating is that they are separated due to differences in songs and beaks, individuals only recognize and respond to songs of their own species. Therefore, geographic isolation and different environments led to changes in traits that affected mating.

Which energy is affected by an object's mass?

statuscvo [17]

Answer:

A potential

B kinetic

Explanation:

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

$K.E = \frac{1}{2}MV^{2}$

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

$P.E = mgh$

Where, P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Both potential and kinetic energy is affected by an object's mass.
