Crossing over is the main event in meiosis and heredity as it leads to genetic variation.
<h3>What is genetic variation?</h3>
Genetic variation is the changes that take place in the genes of individuals that can lead to the formation of new characters.
it generally occurs in meiosis specifically during crossing over.
Thus, it can be concluded that crossing over between non-sister chromatids during meiosis is significant in heredity as it leads to genetic variation.

Arctic & Alpine Tundra. Coniferous Forest (Taiga)
Tundra Biome. Alpine tundra in the Rocky Mountains of Colorado.
Coniferous Forest Biome.
The strong gravity keeps the plantets from escaping so they have thick atmospheres
Data given
Initial Velocity = 0 m/s
Change in distance x = 60m
Change in time = 3.5s
Acceleration due to gravity = -9.81 m/s^2
Required
Final Velocity (vf) = ?
Solution
According to first equation of motion
Vf = Vi+gt
Put the values, we will get
Vf = 0 + (-9.81) (3.5)
-34.3 m/s (Answer)
