input with options: Answer the following question given this paragraph: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis. Q: Which lipid is mainly responsible for narrowing arteries and causing the disease atherosclerosis? A:
OPTIONS:
- monoglyceride
- unsaturated fat
- saturated fat
- cholesterol
output: cholesterol

Q: Answer the following question given this paragraph: The first year of life after birth is called infancy. During infancy, a baby grows very quickly. The baby's length typically doubles and her weight triples by her first birthday. Many other important changes also occur during infancy:. Q: What is the first year of life following birth called? A:

OPTIONS:
- baby
- childhood
- toddler
- infancy

A: infancy

input: OPTIONS:
- Cells
- organs
- enzymes
- hormones Now, answer this question: Answer the following question given this paragraph: How Hormones Work Hormones cause changes in target cells by binding to specific cell-surface or intracellular hormone receptors, molecules embedded in the cell membrane or floating in the cytoplasm with a binding site that matches a binding site on the hormone molecule. In this way, even though hormones circulate throughout the body and come into contact with many different cell types, they only affect cells that possess the necessary receptors. Receptors for a specific hormone may be found on or in many different cells or may be limited to a small number of specialized cells. For example, thyroid hormones act on many different tissue types, stimulating metabolic activity throughout the body. Cells can have many receptors for the. Q: Although what biochemicals circulate throughout the body and come into contact with many different cell types, they only affect cells that possess the necessary receptors? A:
A:
output: hormones

Answer the following question given this paragraph: Many STIs are caused by bacteria. Some of the most common bacterial STIs are chlamydia, gonorrhea, and syphilis. Bacterial STIs can be cured with antibiotics. Q: What are most stis caused by? A:

OPTIONS:
- vaccines
- parasites
- viruses
- bacteria

Answer: bacteria

Problem: OPTIONS:
- acidophobes
- acidic
- acid heads
- acidophiles
Q: Answer the following question given this paragraph: Acidophiles are organisms that "love" acids. They live in very acidic environments, such as acid mine drainage. They are also found near vents of volcanoes. The most acidophilic archaeans can thrive at negative pH values. No other organisms can survive in such acidic conditions. Q: Organisms that "love" acids are known as what? A:
Answer: acidophiles

Answer the following question given this paragraph: Proteins Function as Enzymes If you were trying to type a paper, and every time you hit a key on your laptop there was a delay of six or seven minutes before you got a response, you would probably get a new laptop. In a similar way, without enzymes to catalyze chemical reactions, the human body would be nonfunctional. It functions only because enzymes function. Enzymatic reactionschemical reactions catalyzed by enzymesbegin when substrates bind to the enzyme. A substrate is a reactant in an enzymatic reaction. This occurs on regions of the enzyme known as active sites (Figure 2.27). Any given enzyme catalyzes just one type of chemical reaction. This characteristic, called specificity, is due to the fact that a substrate with a particular shape and electrical charge can bind only to an active site corresponding to that substrate. Q: What is the name of a reactant in an enzymatic reaction? A:

OPTIONS:
- membrane
- Scar
- tissues
- substrate

Answer:
substrate
