Answer: check explanation.

Explanation:

Transcription is a process in which protein is being produced or synthesized. Transcription can also be defined as the transfer of genetic instructions in DNA to RNA. Transcription uses the DNA in the nucleus to make an RNA molecule. Then, the RNA will now leave the nucleus for ribosome(cytoplasm).

Transcription takes place in three steps and they are;

(1). INITIATION STEP: in this step, the RNA polymerase(an enzyme) binds to the promoter.

(2). ELONGATION STEP: in this step, we have the addition of nucleotides to the mRNA strand.

(3). TERMINATION STEP: In this step, we have the RNA polymerase crosses a terminating sequence in the gene. Here, the mRNA strand detaches itself from the DNA.

After the three steps above, we have the processing of the mRNA. This additional processing include, Splicing(removal of introns from mRNA), Editing( changes in nucleotides in mRNA) and Polyadenylation(addition of tail).

An experiment in which only one variable is changed is a(an) __________ experiment.
MrMuchimi

Answer;

D. controlled

An experiment in which only one variable is changed is a controlled experiment.

Explanation;

-A control experiment is an experiment where the researcher only changes one variable at a time in order to isolate the results.

In a controlled experiment, most conditions are constrained so that they do not change. One or two other conditions are then changed and measured by the experimenter. These are known as the independent variables.

For example; An experiment where all subjects involved in the experiment are treated exactly the same except for one deviation.

Ultraviolet rays from the sun are dangerous because they can damage skin. Why do ultraviolet rays cause damage?
Sonja [21]

Answer:

<em>UV rays are highly injurious to living organisms since </em><em>DNA</em><em> </em><em>and</em><em> </em><em>proteins</em><em> </em><em>of</em><em> </em><em>living</em><em> </em><em>organisms</em><em> </em><em>preferentially</em><em> </em><em>absorb</em><em> </em><em>U.V</em><em> </em><em>rays</em><em> </em><em>and</em><em> </em><em>it's high</em><em> </em><em>energy</em><em> </em><em>breaks</em><em> </em><em>chemical</em><em> </em><em>bonds</em><em>. UV rays damage DNA and mutation may occur. It causes ageing of the skin, damage to skin cells and various types of skin cancers.</em>

Many marine sponges contain a biological catalyst that blocks a certain step in the separation of chromosomes. Which cellular pr
Zinaida [17]

A  . mitosis

Explanation:

The cellular process that would be directly affected by this catalyst is the mitosis.

Mitosis is as form of cell division in body cells. It ensures that restores the number of chromosomes in the daughter cell.

  • During mitosis, chromosomes are replicated and are facilitated by certain catalysts.
  • If a catalyst blocks off the separation of chromosomes, the process of mitosis will be affected and might not occur.

Frequency theory of hearing

According to the frequency theory of hearing the auditory nerve's impulse corresponds to the frequency of a tone. This allows the recognition of pitch. Sounds are detected in the ear as acoustic signal in the external and middler ear. It is later on transformed in an electrical impulse that a nerve can detect in the cochlea. The theory assumes that a nerve can fire at rates of 20 to 20000 times per second. This is the assumption that the frequency of human hearing range is at 20 to 20000.
