transgenic organism has a specific desirable gene transplanted to another organism. so the first step is to identify the desirable gene. ans is D. Find a gene in one species that would be useful if added to the DNA of another species.
Answer:
wall
Explanation:
It is composed of peptidoglycan. The wall gives the cell its shape and surrounds the cytoplasmic membrane, protecting it from the environment.
yes, Muscularis mucosa - The stomach and small intestine's mucosa are pulled into undulating folds by a thin layer of smooth muscle that is constantly tensed. The surface area that is available for digestion and absorption is significantly increased by these folds.
The submucosa is located directly beneath the mucosa, as its name suggests. It joins the underlying muscularis to the overlaying mucosa by way of a large layer of dense connective tissue. It has blood and lymphatic vessels (which carry nutrients that have been absorbed), as well as a few submucosal glands that secrete digestive juices. Additionally, it functions as a passageway for the submucosal plexus, a densely branched network of nerves.
These layers compress to encourage mechanical digestion, expose more of the food to the chemicals that aid in digestion, and transport the food along the canal.

Prophase I
The chromosomes condense, and the nuclear envelope breaks down & crossing-over occurs.
Metaphase I
Pairs of homologous chromosomes move to the equator of the cell.
Anaphase I
Homologous chrmosomes move to the oppisite poles of the cell.
Telophase I and Cytokinesis
Chromosomes gather at the poles of the cells & the cytoplasm divides.
Prophase II
A new spidle forms around the chromosomes.
Metaphase II
Chromosomes line up at the equator.
Anaphase II
Centromeres divides & chromatids move to the opposite poles of the cells.
Telophase II and Cytokinesis
A nuclear envelope forms around each set of chromosomes & the cytoplasm divides.
