Q: Answer the following question given this paragraph: Lipids are one of four classes of biochemical compounds, which are compounds that make up living things and carry out life processes. (The other three classes of biochemical compounds are carbohydrates, proteins, and nucleic acids. ) Living things use lipids to store energy. Lipids are also the major components of cell membranes in living things. Types of lipids include fats and oils. Q: Name the missing call of biochemical compound: carbohydrates, proteins, nucleic acids. A:

OPTIONS:
- enzymes
- microorganisms
- tissues
- lipids

A: lipids

input: OPTIONS:
- ten volts
- eight volts
- six volts
- twelve volts Now, answer this question: Answer the following question given this paragraph: The description given above describes the process that occurs in one cell of a lead-acid battery. Because cars require a battery with a higher voltage than can be obtained with a single cell, car batteries generally consist of several cells connected together to produce the desired voltage output. A typical car battery will generate twelve volts of electricity. Q: How much electricity is generated by an average car battery? A:
A:
output: twelve volts

Answer the following question given this paragraph: In the lungs, air is diverted into smaller and smaller passages, or bronchi. Air enters the lungs through the two primary (main) bronchi (singular: bronchus). Each bronchus divides into secondary bronchi, then into tertiary bronchi, which in turn divide, creating smaller and smaller diameter bronchioles as they split and spread through the lung. Like the trachea, the bronchi are made of cartilage and smooth muscle. At the bronchioles, the cartilage is replaced with elastic fibers. Bronchi are innervated by nerves of both the parasympathetic and sympathetic nervous systems that control muscle contraction (parasympathetic) or relaxation (sympathetic) in the bronchi and bronchioles, depending on the nervous system's cues. In humans, bronchioles with a diameter smaller than 0.5 mm are the respiratory bronchioles. They lack cartilage and therefore rely on inhaled air to support their shape. As the passageways decrease in diameter, the relative amount of smooth muscle increases. The terminal bronchioles subdivide into microscopic branches called respiratory bronchioles. The respiratory bronchioles subdivide into several alveolar ducts. Numerous alveoli and alveolar sacs surround the alveolar ducts. The alveolar sacs resemble bunches of grapes tethered to the end of the bronchioles (Figure 39.10). In the acinar region, the alveolar ducts. Q: In the lungs, air is diverted into smaller and smaller passages called what? A:

OPTIONS:
- ion channels
- alveoli
- ectoderm
- bronchi

Answer: bronchi

Problem: OPTIONS:
- two million
- fifty million
- eight million
- five million
Q: Answer the following question given this paragraph: Almost 5 million people die each year because of air pollution. In fact, polluted air causes more deaths than traffic accidents. Air pollution harms the respiratory and circulatory systems. Both outdoor and indoor air can be polluted. Q: Nearly how many millions of people die yearly due to air pollution? A:
Answer: five million

Problem:OPTIONS:
- in warmer waters
- on the ocean floor
- along reefs
- along coasts

Answer the following question given this paragraph: The oceans are most polluted along coasts. Why do you think that's the case? Of course, it's because most pollution enters the oceans from the land. Runoff and rivers carry the majority of pollution into the ocean. Many cities dump their wastewater , water mixed with waste, directly into coastal waters. In some parts of the world, raw sewage and trash may be thrown into the water ( Figure below ). Coastal water may become so polluted that people get sick if they swim in it or eat seafood from it. The polluted water may also kill fish and other ocean life. Q: Where are the oceans most polluted? A:
****
A: along coasts

Problem:OPTIONS:
- parasites
- neutrophils
- antibodies
- lymphocytes

Answer the following question given this paragraph: Lymphatic vessels make up a body-wide circulatory system. The fluid they circulate is lymph. Lymph is a fluid that leaks out of capillaries into spaces between cells. As the lymph accumulates between cells, it diffuses into tiny lymphatic vessels. The lymph then moves through the lymphatic system from smaller to larger vessels. It finally drains back into the bloodstream in the chest. As lymph passes through the lymphatic vessels, pathogens are filtered out at small structures called lymph nodes (see Figure above ). The filtered pathogens are destroyed by lymphocytes. Q: What destroys the filtered pathogens? A:
****
A:
lymphocytes
