Answer:
effector
Explanation:If the value is not at the set point or is outside the normal range, the control center sends a signal to the effector. The effector is an organ, gland, muscle, or other structure that acts on the signal from the control center to move the variable back toward the set point.
Answer:
The correct option is option A
Explanation:
Restriction enzymes are endocleases that cleave DNA fragment (<u>of usually four, five or six nucleotide long</u>) at <u>specific sites to produce blunt or sticky ends</u>. They <u>recognize palindromic sequences of host DNA when cleaving the specific sites</u>. The sequences below (on complementary strands) give an example of a palindromic sequences.
5'-CCC║GGG-3'
3'-GGG║CCC-5'
As can be seen above, when read from 5' to 3', the two sequences are the same despite being on opposing strands. And when cut between the guanine (G) and cytosine (C) (as shown above), it produces a blunt end. But when cut as shown below produces a sticky end.
5'- G║AATTC -3'
3'- CTTAA║G -5'
The explanation above shows options C and D are right while option A is wrong (hence the correct option).
Also, bacteria prevent their own DNA from been digested by restriction enzymes by adding methyl group to their restriction sites <u>which prevents restriction enzymes from recognizing restriction sites of their DNA;</u> this generally makes bacterial DNA to be highly methylated. This explanation makes option B right also.
Answer:
Sexual reproduction.
Explanation:
Like most mammals, giraffes produce sexually, meaning that both parents contribute to the DNA of the offspring.
Answer:
Diana is correct.
Explanation:
because earthquakes occur when two plates slip. even if it happens underwater it affects the enviroment around itself usually causing damage.
