Answer:
We are getting taller because of improved nutrition and health.
Explanation:
Height, as a polygenic trait, is controlled by more than 2 genes in humans. Height as a trait in humans can be determined by the genetic code of an individual as well as the environmental conditions where such individual lives in. Environmental factors such as good and conducive environment, improved standard of living, and most especially nutrition and health.
The most reasonable cause why we seem quite taller than humans of 100 years ago is simply as a result of improved nutrition and health which was made possible by our advances in science and technology. Good standard of living and improved nutrition is responsible for we getting taller.
If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.
Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.
The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.

I would say b and a don't quote me if I'm wrong :P
Answer:
Hi
hope this helps :3
Explanation:
DNA is called the blueprint of life because it contains the instructions needed for an organism to grow, develop, survive and reproduce.
It can cause loss of memory, hunger, and time
