Answer:

The role of the Polymerase is to make more DNA from nucleotides. There a few different types of Polymerase, and they work in pairs to replicate cells.

Explanation:

DNA polymerase I and DNA polymerase III are the main DNA polymerases. These are involved in DNA replication, proofreading and repair of DNA. During the process of replication, DNA polymerase adds nucleotides on the RNA primer. ... It is very accurate in assembling nucleotides during replication.

cestrela7 [59]

Complete question:

A researcher had 15 pure-bred wild mice which were brown and all were females. They were all mated with a male called Bob. All the offspring were brown. These were then crossed among themselves with the following results: 293 brown and 115 white.

(i). Determine the color of Bob.

(ii). Determine which color is dominant.

(iii). Work out the ratio of brown to white in the ‘grandchildren.’

(iv). If the researcher crosses two of the white 'grandchildren', determine the color of their offspring.

Use the Punnett square to work out your answers

Answer:

(i). Determine the color of Bob. BOB IS WHITE

(ii). Determine which color is dominant. BROWN IS DOMINANT

(iii). Work out the ratio of brown to white in the ‘grandchildren.’

PHENOTYPIC RATIO BROWN TO WHITE 3:1

(iv). If the researcher crosses two of the white 'grandchildren', determine the color of their offspring. THE WHOLE PROGENY WILL BE WHITE

4. The mass of ball A is 10 kilograms and the mass of ball B is 5 kilograms. If

Nookie1986 [14]

4.) We are told that ball A is travelling from right to left, which we will refer to as a positive direction, making the initial velocity of ball A, +3 m/s. If ball B is travelling in the opposite direction to A, it will be travelling at -3 m/s. The final velocity of A is +2 m/s. Using the elastic collision equation, which uses the conservation of linear momentum, we can solve for the final velocity of B.

MaVai + MbVbi = MaVaf + MbVbf

Ma = 10 kg and Mb = 5 kg are the masses of balls A and B.
Vai = +3 m/s and Vbi = -3 m/s are the initial velocities.
Vaf = +2 m/s and Vbf = ? are the final velocities.

(10)(3) + (5)(-3) = (10)(2) + 5Vbf
30 - 15 = 20 + 5Vbf
15 = 20 + 5Vbf
-5 = 5 Vbf
Vbf = -1 m/s

The final velocity of ball B is -1 m/s.

5.) We are now told that Ma = Mb, but Vai = 2Vbi

We can use another formula to look at this mathematically.

Vaf = [(Ma - Mb)/(Ma + Mb)]Vai + [(2Mb/(Ma + Mb)]Vbi

Since Ma = Mb we can simplify this formula.

Vaf = [(0)/2Ma]Vai + [2Ma/2Ma]Vbi
Vaf = Vbi

Vbf = [(2Ma/(Ma + Mb)]Vai + [(Ma - Mb)/(Ma + Mb)]Vbi
Vbf = [2Mb/2Mb]Vai + [(0)/2Mb]Vbi
Vbf = Vai

Vaf = Vbi
Vbf = 2Vbi

If the initial velocity of A is twice the initial velocity of B, then the final velocity of A will be equal to the initial velocity of B.

If the initial velocity of A is twice the initial velocity of B, then the final velocity of B will be twice the initial velocity of B.

<h3>What is phrases ?</h3>

The phrase has a different meaning when used in linguistics than it does in everyday speech. A phrase is typically a collection of words with a common meaning or other importance, such as "all rights reserved," "economical with the truth," "kick the bucket," and similar expressions. It could be a figure of speech, a set expression, a saying or proverb, etc. These are known as phrasemes in linguistics.

According to theories of syntax, a phrase is any group of words—or perhaps just one word—that has a specific function within the syntactic framework of a sentence. It is not required to have any specific importance or meaning, or to even exist elsewhere except the sentence under study.
