Biology

Let's use process of elimination to answer this question!

D is wrong, and we know this because of the names of DNA and RNA. The D in DNA stands for deoxyribose, and the R in RNA stands for ribose. These are the types of sugars in each nucleic acid. Therefore, they don't both contain a ribose sugar.

C is wrong, and this is because RNA does not contain thymine, but uracil instead.

B is wrong, and we know this because we know that RNA is composed of only one strand, and therefore it is not composed of multiple stands (plural).

Therefore, A must be right. We can confirm this, because we know that polymers are large molecules consisting of repeated subunits. DNA and RNA are both polymers consisting of nucleotides.<span />

Which are tunics (layers) that make up the gastrointestinal wall?
AlekseyPX

The gastrointestinal wall is composed of four layers or tunics:

  • Mucosa
  • Submucosa
  • Muscularis mucosa
  • Serosa

The innermost tunic of the wall is known as the mucosa or mucous membrane layer. The digestive tract's lumen is lined with it. The mucosa comprises epithelium, a layer of lamina propria, a loose layer of connective tissue, and the muscularis mucosa, a thin layer of smooth muscle.

The mucosa is surrounded by a substantial layer of loose connective tissue known as the submucosa. Blood arteries, lymphatic vessels, and neurons are also present in this stratum. The adventitia is a connective tissue that makes up the digestive tract's outermost layer above the diaphragm. It is referred to as serosa below the diaphragm.
