Answer: crossing over allows for genetic variation

Explanation:

crossing over is the exchange of genes between two chromosomes which ends up resulting in non-identical chromatids that comprise the genetic material of gametes (sperm and eggs).

Basically crossing over makes the chromatids that are held together by a centromere, no longer identical to eachother which creates genetic variation.

Why Should A Potometer be Allowed to stand before starting the Experiment​
mamaluj [8]
It is crucial to avoid air bubbles in the assembled potometer. The plant stem must be cut under water to prevent airlocks forming in the xylem. All fittings must be tight so that the only way the apparatus can lose water is by the plant transpiring.

A driver traveling at a speed of 21 m/s tops a hill and spots a deer standing in the middle of the road 90 meters away. He hits
Iteru [2.4K]

Answer:

84m

Explanation:

Using the kinematics equation we can come up with the answer:

d=\dfrac{Vf+Vi}{2}\times t

Where:

Vf = final velocity

Vi = initial velocity

t = time

In your problem we have the following given:

Vf= 0 m/s

Vi = 21 m/s

t = 8 seconds

The Vf is zero because the car stopped. The distance given in this case is not useful in determining the car's distance so we will solve it. So just fill in the equation with the given:

d=\dfrac{Vf+Vi}{2}\times t\\\\d=\dfrac{0m/s+21m/s}{2}\times 8s\\\\d=10.5m/s\times 8s=84m

Thankfully, the deer was not hit!
