Answer:

Protein is broken down into amino acids in the stomach

Explanation:

As you may already know, digestion is the biological process that allows the foods you eat to undergo chemical and physical changes that allow your body to absorb nutrients, minerals, amino acids and all the substances needed by your body.

Physical modifications are responsible for breaking down food into smaller pieces, basically. However, chemical changes are primarily responsible for transforming food into assimilable substances. An example of chemical transformation occurs when protein is broken down into amino acids in the stomach.

nata0808 [166]

Answer:

plant cell

Explanation:

The Golgi apparatus is a cell organelle responsible for modifying, sorting and packaging proteins and lipid molecules into vesicles (i.e., Golgi vesicles) for their delivery to targeted cell sites. A plant cell can contain many -even hundreds- of Golgi apparatus. During cell division of plant cells, Golgi vesicles combine at the metaphase plate in order to form a structure called phragmoplast. Subsequently, the cell plate formed by phragmoplast vesicles grows from the center to the cell walls. Finally, the vesicle membranes fuse to form a plasma membrane that divides the plant cell into two cells.

<h3>What is catfish?</h3>

Catfish and catfish are common designations given to fish of the order Siluriformes in most of South America.About 2,200 species of these fish are known, classified into almost 40 families (only two, Ariidae and Plotosidae, have marine species). They are found almost all over the world, but more than half of the known species are native to South America.

With this information, we can conclude that the catfish (Ictaluruspunctatus) is a representative fish of the order Siluriformes, family Ictaluridae, characterized by not having scales.
