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?

<span>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.</span>

Answer:

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

In a standard game of pool, there are 15 balls labeled 1 through 15. a) In how many ways can the 15 balls be ordered? (5 points)
katovenus [111]

Answer:

<h2>a) 1.308*10¹² ways</h2><h2>b) 455 way</h2>

Step-by-step explanation:

If  there are 15 balls labeled 1 through 15 in a standard football game, the order of arrangement of the 15 balls can be done in 15! ways.

15! = 15*14*13*12*11*10*9*8*7*6*5*4*3*2

15! = 1.308*10¹² ways

b)  If 3 of the 15 balls are to be chosen if order does not matter, this can be done in 15C3 number of ways. Since we are selecting some balls out of the total number of balls, we will use the concept of combination.

Using the combination formula nCr = n!/(n-r)!r!

15C3 = 15!/(15-3)!3!

15C3 = 15!/12!3!

15C3 = 15*14*13*12!/12!*6

15C3 = 15*14*13/6

15C3 = 455 ways

The quotient of the sum of 2t and 2, twice the cube of s
natali 33 [55]

Answer: \frac{2t+2}{2s^3}

Step-by-step explanation:

Since you did not indicate what you need to do, I assume that you have to write an expression using the sentence given in the problem.

In order to solve this exercise, it is importat to remember the following information:

1. The quotient is the result of a division.

2. The sum is the result of an addition.

3. The word "twice" indicates a multiplicatio by 2.

4. The word "cube" indicates an exponent 3.

Then, keeping on mind the explained above and the data given in the exercise, you know that:

-The sum of 2t and 2 can be expressed as:

2t+2

- Twice the cube of s can be expressed in the following form:

2s^3

Therefore, you can dermine that "the quotient of the sum of  2t and 2 and twice the cube of s" is represented with the following expression:

\frac{2t+2}{2s^3}

Archimedes (ca. 287-212 B.C.) was able to use clever geometric means to determine the relative volumes of a cylinder and the con
VLD [36.1K]

Answer:

The ration of the volume of  cone to that of   cylinder is   \frac{V_{cone}}{V_{cy}} = \frac{1}{3}  

Step-by-step explanation:

From the question we are told that

 The volume of a cone is mathematically represented as

        V_{cone} = \frac{1}{3} \pi r^2 h

The volume of a cylinder is mathematically represented as

       V_{cy} = \pi r^2 h

Now the ratio we are to obtain is

          \frac{V_{cone}}{V_{cy}}  = \frac{\frac{1}{3}  \pi r^2 h}{\pi r^2 h}    

                   \frac{V_{cone}}{V_{cy}} = \frac{\frac{1}{3} }{1}         Note: this is possible because the height and base

                   \frac{V_{cone}}{V_{cy}} = \frac{1}{3}        radius  are the same
