Answer:a. prokaryotic. cellsExplanation:
Answer:
It would change the nucleotide sequence of the transcribed mRNA
Explanation:
During the process of transcription, a DNA template is used to synthesize a mRNA molecule. The nucleotides in the DNA molecule undergo a complementary base pairing to form the nucleotides on the mRNA. This means that the order of sequence on the DNA determines the order of sequence on the mRNA.
In a case where the nucleotide sequence of a DNA segment changes in the process of MUTATION, the sequence of nucleotides in the mRNA strand will also change. For example, if sequence: ATT on the DNA produces UAA on the mRNA, a change to AAT on the DNA will cause the mRNA sequence to change to UUA.
Answer: a. Increasing the surface area for diffusion
Explanation:
When the air is inhaled through the nostrils, the air containing the oxygen the air diffuses inside the alveoli. The alveoli are the tiny sacs where air enters and exchange of gases takes place. From the alveoli the oxygen enters into the blood stream. The oxygen is utilized by the cells for respiration. The increase in network and number of the alveoli will increase the surface area for the diffusion of oxygen and hence, will speed up the respiration process.
False, Xylem transports water.
