At the superior end of the esophagus, the superior esophageal sphincter is a thickened ring of ______ muscle marking the area where the esophagus and the pharynx meet.

Answers

The superior esophageal sphincter is a muscular ring that separates the pharynx from the esophagus, has voluntary activity and is responsible for initiating swallowing.

What is the superior esophageal sphincter?

It is located immediately after the pyriform sinuses, it is a muscular ring located in the high pressure area between the pharynx and the esophagus.

This prevents the passage of air into the digestive tract during inspiration and the reflux of gastric material into the pharynx, relaxing to open the esophagus.

In order for a muscle-building athlete to keep muscles in good shape, it is necessary to synthesize more muscle protein than is consumed, which is known as nitrogen balance..

Therefore, we can conclude that the superior esophageal sphincter is a muscular ring that separates the pharynx from the esophagus, has voluntary activity and is responsible for initiating swallowing.

Based on the DNA sequence: TAC,CCA,TAG, CAC ,GTT,ACA, ACG

The mRNA produced by transcription is: AUG, GGU, AUC, GUG, CAA, UGU, UGC. The amino acid sequence produced by translation is: Met, Gly, Isoleucine, Val, Glu, Cys, Cys.

What is transcription and translation in genetics?

Transcription is the process by which RNA molecules are made from DNA molecules.

The RNA molecules produced are known as messenger RNA or mRNA which are then used to make proteins.

Translation is the process by mRNA molecules are used to make proteins from amino acids at the ribosomes.

The nucleotides in the mRNA are read in triplets known as codons.

For the given DNA sequence: TAC,CCA,TAG, CAC ,GTT,ACA, ACG

The mRNA produced is: AUG, GGU, AUC, GUG, CAA, UGU, UGC.

As trees grow over time, the trees form new cells in circles called annual growth rings. These rings show the amount of
wood produced during one growing season or year, as well as the effects of different environmental conditions on the
tree. The figure shows the growth rings for two different types of trees growing in the same forest area

Answers

Due to differences in age and growth rate of the trees, the growth rings for two different types of trees growing in the same forest area may vary.

What are annual growth rings?

Annual growth rings are rings of cells which form as trees grow over time and these rings represent the amount of wood produced during on growing season.

Annual growth rings provides estimates of the age of trees.

Distinct annual growth rings are formed in trees growing in temperate regions where there are sharp climatic variations.

The diameter and thickness of growth rings of different trees vary since trees grow and different rates.
