Answer:
You are saying which one but what is which one???
Explanation:
D.
They have the same number of protons as electrons.
Explanation:
Protons are found in the nucleus of the atom and have a positive charge while electrons orbit around the nucleus and have a negative charge. Usually, in a neutral atom of an element, the number of protons is equal to the number of electrons. This is why the atom has no charge because the positive and negative charges cancel out. When an atom loses an electron its charge turns positive while when it gains an electron its charge turns negative.
velocity= distance / time
your distance is 180 miles
your time is 3 hours
180 divided by 3 = 60
Answer;
Light microscope
Explanation;

-Light microscopes use a single lens to magnify an object and cannot reach high magnification. Illuminator is the light source for a microscope, typically located in the base of the microscope.
C)The two species cannot have viable offspring together.
An ecological niche can be defined as the functional role played by the organism or species in order to survive in it's habitat. Like the type of food consumed by the organism, type of mating mating season and others.
In the given situation, the thick beak birds likely to develop in a new species because of this typically adaptation. The two species may exhibit reproductive isolation as they may not be capable of inbreeding among themselves and cannot produce viable offspring together.
