Restriction enzymes identifies specific sequences in the DNA (Deoxyribonucleic acid) and cut the DNA to produce fragments. These enzymes are used in the production of the recombinant DNA. These enzymes cut out the specific required fragment of the DNA, which is then incorporated into the bacteriophage. This recombinant phage DNA then infects the bacterial cell, which produces new particles with this foreign recombinant DNA.

HACTEHA [7]

Answer:

Flock X  - 41 % - 12

Flock Y - 33% -  10

Flock Z - 26% -  8

Explanation:

All you really need to do is follow the instructions.

Here is the information given:

               Total pieces of

                Food Eaten            Percentage(%)                             Number of birds      

Flock X              123             123/300 = 0.41 x 100% = 41%          0.41 x 30 = 12

Flock Y               99              99/300 = 0.33 x 100% = 33%        0.33 x 30 = 10

<u>Flock Z               78              78/300 = 0.26 x 100% = 26%        0.26 x 30 = 8   </u>

Total                 300                                                    100%                           30

In the percentage portion you need to multiply it by 100% if you want to get the percentage in percent. By multiplying it by the total number of birds, you will be able to get the number of birds in each flock.

PLEASE HELP I WILL GOVE BRAINLIEST!! What do mutations cause?
goblinko [34]
Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism.
