The correct option is Chromosomes.

Step-by-step explanation:

The correct option is Chromosomes.

In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Chromosomes are not visible in the cell’s nucleus. Chromosomes are not visible, not even under a microscope. However the DNA becomes more tightly packed during the cell division and is then visible under a microscope.

Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections...

Nancy found that x = 1 is one solution to the quadratic equation (x + 2)2 = a. What is the value of a?

solniwko [45]

ANSWER

a=9

EXPLANATION

The given quadratic equation is

${(x + 2)}^{2} = a$

If x=1 is a solution, then it must satisfy this equation:

${(1 + 2)}^{2} = a$

${3}^{2} = a$

$a = 9$

Therefore the value of 'a' is 9

Simplify these expressions. a.2r+3+4r. b.8+3d+d. c.mn+ (-3mm)+6 d. 10s + (-10) + (-4s)

Maru [420]

Step-by-step explanation:

<em>Combine like terms</em>

a. 2r + 3 + 4r = (2r + 4r) + 3 = 6r + 3

b. 8 + 3d + d = (3d + d) + 8 = 4d + 8

c. mn + (-3mn) + 6 = (mn - 3mn) + 6 = -2mn + 6

d. 10s + (-10) + (-4s) = (10s - 4s) - 10 = 14s - 10

<em>Terms are called "like terms" if they have the same variable part (the same letters in the same powers). Like terms differ at most coefficient.</em>
