Answer the following question given this paragraph: Respiration is the process in which gases are exchanged between the body and the outside air. The lungs and other organs of the respiratory system bring oxygen into the body and release carbon dioxide into the atmosphere. Q: What is the process in which gases are exchanged between the body and the outside air? Choices: - ingestion - metabolism - precipitation - respiration A:
(Answer)
respiration
Ques: Answer the following question given this paragraph: Acid rain is rain that has a pH less than 5 ( Figure below ). Acidity is measured on the pH scale . Lower numbers are more acidic, and higher numbers are less acidic (also called more alkaline ). An acid has a pH of less than 7. The pH of normal rain is 5.6. It's slightly acidic because carbon dioxide in the air dissolves in rain. This forms carbonic acid, a weak acid. Q: What is the term for rain consisting of water with a ph below 5? Choices: - carbon rain - produce rain - Hot Rain - acid rain A:
Ans: acid rain

Answer the following question given this paragraph: Chromosome Structural Rearrangements Cytologists have characterized numerous structural rearrangements in chromosomes, including partial duplications, deletions, inversions, and translocations. Duplications and deletions often produce offspring that survive but exhibit physical and mental abnormalities. Cri-du-chat (from the French for "cry of the cat") is a syndrome associated with nervous system abnormalities and identifiable physical features that results from a deletion of most of the small arm of chromosome 5 (Figure 7.11). Infants with this genotype emit a characteristic high-pitched cry upon which the disorder's name is based. Q: Structural rearrangements of what include partial duplications, deletions, inversions, and translocations; duplications and deletions often produce offspring that survive but exhibit physical and mental abnormalities? Choices: - neutrons - phenotypes - cells - chromosomes A:
(A).
chromosomes
Ques:Answer the following question given this paragraph: 5.2 Drag Forces 5. Athletes such as swimmers and bicyclists wear body suits in competition. Formulate a list of pros and cons of such suits. Two expressions were used for the drag force experienced by a moving object in a liquid. One depended upon the speed, while the other was proportional to the square of the speed. In which types of motion would each of these expressions be more applicable than the other one? 7. As cars travel, oil and gasoline leaks onto the road surface. If a light rain falls, what does this do to the control of the car? Does a heavy rain make any difference? 8. Why can a squirrel jump from a tree branch to the ground and run away undamaged, while a human could break a bone in such a fall?. Q: Athletes such as swimmers and bicyclists wear body suits in competition to minimize what forces? Choices: - natural forces - rolling forces - activity forces - drag forces A:

Ans:drag forces
Question: Answer the following question given this paragraph: Sulfur Oxygen Compounds The two common oxides of sulfur are sulfur dioxide, SO2, and sulfur trioxide, SO3. The odor of burning sulfur comes from sulfur dioxide. Sulfur dioxide, shown in Figure 18.47, occurs in volcanic gases and in the atmosphere near industrial plants that burn fuel containing sulfur compounds. Q: What sulfur compound occurs in volcanic gases and in the atmosphere near industrial plants? Choices: - sulfur hydroxide - carbon sulfide - nitrogen sulfide - sulfur dioxide A:
Answer:
sulfur dioxide
