I think it is answer D, Crop plants are removed from the land at harvest, while native plants remain in place even after they die. Not 100% sure so tell me if it was right or not.
Explanation:
If 3x² – 2x + 7 = 0, then (x – 1/3)²
Let's work on 3x² – 2x + 7 0
1st divide all element by 3===> x² – 2/3x + 7/3
Let's complete the square of x² – 2/3x + 7/3 = (x² – 2/3x) + 7/3
We will complete the square of the parenthesis (x² – 2/3x) + 7/3
-2/3 x = -2x(time)??. so ??=1/3 & its square = 1/9
(x² – 2/3x) + 7/3 be comes [(x² - 2/3x + 1/9) - 1/9 + 7] = (x-1/3)²- 1/9 +7
(x-1/3)²- 1/9 +7 = (x-1/3)² -1/9 +63/9==>(x-1/3)² + 62/9 or
==>(x-1/3)² + 6.987654321 ===>(x-1/3)² + (≈) 7
1 RR,Rr,Rr,rr
2 Bb,Bb,Bb,Bb
3 75%,25%
4 100%
Every box is 25% and when a box has a dominate trait (uppercase) the box will add to the percentage of the dominate trait. (Ex: RR, Rr) ONLY when the box is only lower case (ex:rr) will the box add to the recessive trait
Answer:
Myelin
Explanation:
The myelin sheet is a layer of isolation that protects the neuron and it also increases the conductivity and cuts the time needed for the impulse to travel from one end of the cell to the other. It is made by 2 different cells in our body. In the CNS it is made by oligodendrocytes, and outside the CNS it is made by Schwann cells.
