liberstina [14]

Natural selection is the idea that  organisms that posses favorable traits that enable them to survive in their environment are the ones that live long enough to pass on these traits to their offspring.

<h3>What is natural selection?</h3>

The question is incomplete but I will try my best to explain the idea of natural selection.

The term natural selection refers to the idea put forward by Charles Darwin that organisms that posses favorable traits that enable them to survive in their environment are the ones that live long enough to pass on these traits to their offspring. This is also called the survival of the fittest.

What is a shadow? Explain by giving an example.​
Len [333]

Shadows are made by blocking light. Light rays travel from a source in straight lines. If an opaque (solid) object gets in the way, it stops light rays from traveling through it. This results in an area of darkness appearing behind the object. The dark area is called a shadow

How would you describe the relationship that gravity has with mass and distance.
PSYCHO15rus [73]

Answer:

Mass does not affect gravity and distance has an indirect relationship.

Explanation:

The equation for gravity is, g = \frac{GM}{R^{2} }

where, G = gravitational constant

             M = mass of the planet

             R = distance between the bodies (object and center of planet)

so, gravity depends on the mass of planet,  not on mass of object

 and is inversely proportional to sqaure of distance.
