Answer:
Cephalization does not confer an advantage to free-floating or sea organisms. Many aquatic species display radial symmetry like the jelly fish for instance.
Aquatic animals are not cephalized because they must be able to find food, take caution and defend themselves from harm from all directions.
The Nucleus shows the different functions
Answer:
TO TEST SUPPLY OF WATER QUALITY OF THE LOCALITY Excessively high and low pHs can be detrimental for the use of water. High pH causes a bitter taste, and water pipes.
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).
