Answer the following question given this paragraph: Q: What part of a spider is equipped with poison glands? Choices: - baleen - pedipalps - vacuole - chelicerae A:
chelicerae
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:
peptides
Q: Answer the following question given this paragraph: Neutral amines are weak bases, because the lone pair on nitrogen can act as a proton acceptor. Many smaller amines have very strong and offensive odors. For example, the aptly-named compounds cadaverine and putrescine are foul-smelling amines, formed as a part of the decay process after death. Q: What are the names of foul-smelling amines, formed as a part of the decay process after death? Choices: - formaldehyde and cadaverine - sulfur and formaldehyde - methane and sulfur - cadaverine and putrescine A:
A: cadaverine and putrescine
Question: Answer the following question given this paragraph: Type 2 diabetes occurs when body cells are no longer sensitive to insulin. The pancreas may still make insulin, but the cells of the body cannot use it efficiently. Being overweight and having high blood pressure increase the chances of developing type 2 diabetes. Type 2 diabetes usually develops in adulthood, but it is becoming more common in teens and children. This is because more young people are overweight, due to a high sugar and fat diet, now than ever before. Q: In what type of diabetes can the pancreas still make insulin, but the cells of the body cannot use it efficiently? Choices: - type 3 diabetes - type 1 diabetes - type A diabetes - type 2 diabetes A:
Answer: type 2 diabetes
*Question*
Answer the following question given this paragraph: The following ideas are important in understanding hybridization: 1. Hybrid orbitals do not exist in isolated atoms. They are formed only in covalently bonded atoms. Hybrid orbitals have shapes and orientations that are very different from those of the atomic orbitals in isolated. Q: Hybrid orbitals are formed only in which type of bonded atoms? Choices: - ionically - partially - thermally - covalently A:
**Answer**
covalently
(Q).
Answer the following question given this paragraph: Bombarding a target of one element with high-energy nuclei or subatomic particles can create new elements. Electrostatic repulsions normally prevent a positively charged particle from colliding and reacting with a positively charged nucleus. If the positively charged particle is moving at a very high speed, however, its kinetic energy may be great enough to overcome the electrostatic repulsions, and it may collide with the target nucleus. Such collisions can result in a nuclear transmutation reaction. Q: What normally prevent a positively charged particle from colliding and reacting with a positively charged nucleus, but may be overcome by kinetic energy?. Choices: - kinetic repulsions - toxic repulsion - evaporation repulsions - electrostatic repulsions A:
(A).
electrostatic repulsions
