A scientist is trying to determine the relationship between clams, snails, and squid. When she generates a molecular clock, she is surprised to see that clams and squid are more closely related than clams and snails. Which did the molecular clock data show?

Answers

Molecular clocks use the rate of mutation for biomolecules to work out when two life forms diverged during their development. If the molecular clock shows clams are more closely related to squid than snails, this suggests that the divergence between clams and squid occurred more recently in prehistory than the divergence of clams and snails.

Answer:

Clams and squid have been evolving separately for a shorter time than clams and snails.

You fill a container 3/4 full of water. The amount of water now in the container is 6 quarts. How much can the container hold?a. 12 qt
b. 8 qt
c. 6 qt
d. 14 qt

Answers

To solve this, you need to use cross multiplication. The first fraction, is 3/4 and the second is 6/x, with x meaning how much the container can hold. Multiply 3x(x) and 4x6 equating to 3x=24. From here, use algebra to solve for x, by dividing both sides by three.
Your final answer will be B) 8 qts

Answer:

8 qt

Step-by-step explanation:

Multiply 3x(x) and 4x6 equating to 3x=24 and then algebra to solve for x, by dividing both sides by three.

What is the equation of the line passing through the points (–5, –2) and (3, 14) in slope-intercept form?

Answers

Answer:

2x-y+2= 0

Step-by-step explanation:

(-5,-2)=(x1, y1)

(3, 14) =(x2, y2)

now,

slope(m)= y2-y1 / x2-x1

=14+2 / 3+5

= 16 /8

=2 units

passing point = (-5,-2) = x1,y1

now,

eqn of the line can be represented as,

y -y1 = m (x-x1)

y +2 = 2 (x +5)

y+2 = 2x +10

y = 2x+10-8

0 = 2x+2-y

2x-y+2 =0 is the required eqn

Select the polynomial that is a perfect square trinomial.9x2 + 9x + 1

36b2 − 24b + 8

16x2 + 24x + 9

4a2 − 10a + 25

Answers

Answer: (c)  16x^(2)+24x+9.


Step-by-step explanation:

(a) 9x^(2) +9x+1 cannot be further factorised, so this is not correct option.

(b) 36b^(2)-24b+8 also cannot be expressed as factors, and hence this is too not correct.

(c) 16x^(2)+24x+9=({4x+3} )^2, the correct one.

(d) 4a^(2)-10a+25 cannot be factorised, so its not correct.

Thus, (c) 16x^(2)+24x+9 is the correct option.
Hello,

A hardcover book sells for 24$ at the bookmart. Ben pays 25.02 for the book. What is the sales tax rate?

Answers

The sales tax rate would be 5 percent.

Take the 5 and turn it to a decimal, 0.05.

Times that by 24. 0.05×24= 1.2

That equals out to 1.2, but since we're talking about money we have to add the zero at the end. 1.20.

Now add the 1.20 to 24.

24+1.20= 25.02.

hope this helps!
