Ques: Answer the following question given this paragraph: Nobody really has such colorful eyes! The colors were added digitally after the photo was taken. They represent all the different colors of light. Light is a form of energy that travels in waves. Light of different colors has different wavelengths. Q: Different colors of light differ in terms of which important attribute? Choices: - lenses - prisms - frequencies - wavelengths A:
Ans: wavelengths

Ques: Answer the following question given this paragraph: Plants provide many products for human use. They include timber, medicines, dyes, oils, and rubber. Q: Timber, medicines, dyes, oils, and rubber are just some of the useful products humans derive from what? Choices: - roots - fossils - flowers - plants A:
Ans: plants

Ques: Answer the following question given this paragraph: Plants and animals exist in a cycle; each requires products of the other. The thousands of coordinated chemical reactions that keep cells alive are referred to collectively as metabolism. In general, metabolic reactions are divided into two classes: the breaking down of molecules to obtain energy is catabolism, and the building of new molecules needed by living systems is anabolism. Q: What is the term for the metabolic reaction where living systems build new molecules? Choices: - symbolism - connectionism - metabolism - anabolism A:
Ans: anabolism

Ques: Answer the following question given this paragraph: Protein A large part of protein digestion takes place in the stomach. The enzyme pepsin plays an important role in the digestion of proteins by breaking down the intact protein to peptides, which are short chains of four to nine amino acids. In the duodenum, other enzymes trypsin, elastase, and chymotrypsinact on the peptides reducing them to smaller peptides. Trypsin elastase, carboxypeptidase, and chymotrypsin are produced by the pancreas and released into the duodenum where they act on the chyme. Further breakdown of peptides to single amino acids is aided by enzymes called peptidases (those that break down peptides). Specifically, carboxypeptidase, dipeptidase, and aminopeptidase play important roles in reducing the peptides to free amino acids. The amino acids are absorbed into the bloodstream through the small intestines. The steps in protein digestion are summarized in Figure 34.17 and Table 34.6. Q: The enzyme pepsin plays an important role in the digestion of proteins by breaking down intact protein to what short-chain amino acids? Choices: - protons - proteins - lipids - peptides A:
Ans:
peptides
