PLEASE HELP ASAPExplain how the number of chromosomes per cell is cut in half during meiosis, in which the
diploid parent cell produces haploid daughter cells.

Answers

During meiosis I, homologous chromosomes are pulled apart to produce two daughter cells. These daughter cells then divide again in meiosis II, only now it is the sister chromatids that are split apart. The ploidy of the daughter cells is less than the ploidy of the parent cells, thus resulting in diploid parent cells and haploid daughter cells.

Use a transformation to solve the equation. k/-4 = - 0.8

A.

k = –3.2

B.

k = –0.2

C.

k = 0.2

D.

k = 3.2

Answers

k/-4 = - 0.8,
make k the subject of the equation by multiplying through by -4,
   this means, (k/-4) x -4 = - 0.8 x -4
   this should give you k = -0.8 x -4, the negatives will cancel out to give you positive values,
   so k= 3.2

your answer is D

Which of the following is the solution to 4 | x + 3 | ≥ 8?A. x ≤ -5 and x ≥ -1
B. x ≥ -1
C. x ≤ -5 or x ≥ -1
D. x ≥ -5 or x ≥ -1

Answers

First we get rid of the 4 by dividing by it:

4 | x + 3 | ≥ 8 =>
| x + 3 | ≥ 2

Then eliminate the absolute operator like this:

| x + 3 | ≥ 2 =>

-x-3 ≥ 2 or x+3 ≥ 2

Simplify:

-x ≥ 5 or x ≥ -1=>
x ≤ -5 or x ≥ -1

That's answer C

either 4(x + 3) >= 8 or 4(x + 3) <= -8

4x + 12 >=8
4x >= =4
x >= -1
or

4x + 12 <= -8
4x <= -20
x <= -5

Answer is C
