The prenatal muscle originates from the myotome. The myotome produces presumed myoblasts that form the satellite cells. Answer: myotome / satellite cells.

<h3>How is the skeletal muscle originated and repaired?</h3>

Myogenesis is the process of skeletal muscle formation during the embryonal stage. Structures derived from the mesodermal produce the firsts muscle fibers of the body, and then other additional fibers.

The myotome is a primitive muscular structure that contains progenitor muscle cells. Embryonary myotome cells produce two types of cells,

  • presumed myoblasts that constitute a store of cells that can multiplicate through mitosis

  • properly said myoblasts that can not suffer mitosis

Some of the presumed myoblasts can differentiate into other cells, and some others remain undifferentiated, turning into satellite cells.

This is, progenitor cells in the myotome originate presumed myoblasts, and then these last ones produce satellite cells located in the postnatal skeletal muscle.

Satellite cells are involved in the postnatal process of muscle repair. They suffer successive mitosis producing new myoblasts and more satellite cells.

  • In the embryo, the early skeletal muscle originates from the  <u>myotome.</u>
  • In the adult, skeletal muscle is repaired by fusion of _<u>Satellite cells</u>_ with muscle fibers.

Reptiles are better suited to dry land than their amphibian ancestors because
Vaselesa [24]

Answer:

<u><em>All of the above.</em></u>

Explanation:

1. Their watertight skin minimizes moistures loss: <em>Reptiles have a reputation that they are “slimy” when we touch and hold them; however, they have dry skin, which has even fewer glands than mammals or amphibians. The main special feature of their skin is that the epidermis is heavily keratinized with a layer, which also prevents water loss.</em>

2. Amphibians must lay eggs in water or in moist soil to reduce moisture loss: <em>Because amphibian eggs don't have an amnion, the eggs would dry out if they were laid on the land, so amphibians lay their eggs in water.</em>

3. Reptile egg shells are harder than amphibians' eggs: <em>Reptile eggs are coated with a leathery or brittle coating, and the animals that hatch from them are miniature versions of the full-sized animal parent. In contrast, amphibian eggs are transparent and jelly-like. The animals that hatch from them still must go through metamorphosis.</em>

<u><em>Hope this helps you have a better understanding:) !!</em></u>

Since her stomach was removed, Mrs. Lopez has the most difficulty initiating digestion of: Since her stomach was removed, Mrs. L
Svetllana [295]

Mrs. Lopez has the most difficulty initiating digestion of proteins after her stomach is removed. The correct option is C.

Explanation:

When the stomach is removed due to complications such as in cancers the food eaten directly goes to intestine. Without stomach Mrs Lopez will have difficulty in starting the digestion of protein.

The digestion of protein takes place and starts in the stomach and duodenum of intestine. There are enzymes as pepsin, trypsin and chyomtrypsin secreted  by stomach and pancreas. Pepsin breaks the peptide bonds of protein.

The HCl and the enzymes in stomach initiates the process of digestion of protein. The amino acids formed are ardent in various metabolic processes and repair.

lipids and carbohydrate digestion starts from the mouth only as salivary amylase and lipase initiates the process.
