a cat paw and a bat wing are examples of choose one: a. artificially selected structures. b. embryonic structures. c. homologous structures. d. vestigial structures.

Answers

Answer 1

Answer:

Answer:

Homologous structures

Explanation:

Homologous structures are anatomical features that are similar in structure and origin but may have different functions.

In the case of a cat's paw and a bat's wing, they both have a common underlying structure (similar bone arrangement), but they serve different purposes.

This similarity suggests a shared evolutionary ancestry, as these structures have been modified over time to suit the needs of different species (cats and bats).

If the chemical enzyme pepsin was mixed with some proteins in a test tube in a laboratory, which of these outcomes would you predict?

Answers

Answer:

Pepsin breaks the proteins into simple amino acids.

Explanation:

Digestion is the process of break down of the larger food particles into the simpler substances. The digestion process requires enzymes and digestive juices.

Proteins are made of the amino acids. The enzyme pepsin helps in the breakdown of proteins into the simple peptides. The proteins present in the test tube is hydrolyzed by the enzyme pepsin and breaks down the proteins into simpler amino acids.

Thus, the answer is pepsin breaks the proteins into simple amino acids.

pepsin is one of three principal protein-degrading enzymes in the digestive system, the other two being chymotrypsin and trypsin. During the process of digestion, these enzymes collaborate to break down dietary proteins to their components, i.e., peptides and amino acids.
