Answer the following question given this paragraph: Floods are a natural part of the water cycle, but they can cause a lot of damage. Farms and homes may be lost, and people may die. In 1939, millions of people died in a flood in China. Although freshwater is needed to grow crops and just to live, too much freshwater in the same place at once can be deadly. Q: What natural part of the water cycle can cause damage and death? A:

OPTIONS:
- clouds
- evaporation
- expiration
- floods

Answer: floods

Problem: OPTIONS:
- stimulation of monoglyceride breakdown
- stimulation of monoglyceride production
- stimulation of triglyceride production
- stimulation of triglyceride breakdown
Q: Answer the following question given this paragraph: Hormonal Regulation of Growth Hormonal regulation is required for the growth and replication of most cells in the body. Growth hormone (GH), produced by the anterior portion of the pituitary gland, accelerates the rate of protein synthesis, particularly in skeletal muscle and bones. Growth hormone has direct and indirect mechanisms of action. The first direct action of GH is stimulation of triglyceride breakdown (lipolysis) and release into the blood by adipocytes. This results in a switch by most tissues from utilizing glucose as an energy source to utilizing fatty acids. This process is called a glucose-sparing effect. In another direct mechanism, GH stimulates glycogen breakdown in the liver; the glycogen is then released into the blood as glucose. Blood glucose levels increase as most tissues are utilizing fatty acids instead of glucose for their energy needs. The GH mediated increase in blood glucose levels is called a diabetogenic effect because it is similar to the high blood glucose levels seen in diabetes mellitus. The indirect mechanism of GH action is mediated by insulin-like growth factors (IGFs) or somatomedins, which are a family of growth-promoting proteins produced by the liver, which stimulates tissue growth. IGFs stimulate the uptake of amino acids from the blood, allowing the formation of new proteins, particularly in skeletal muscle cells, cartilage cells, and other target cells, as shown in Figure 37.13. This is especially important after a meal, when glucose and amino acid concentration levels are high in the blood. GH levels are regulated by two hormones produced by the hypothalamus. GH release is stimulated by growth hormone-releasing hormone (GHRH) and is inhibited by growth hormone-inhibiting hormone (GHIH), also called somatostatin. Q: What is the first direct action of growth hormone? A:
Answer: stimulation of triglyceride breakdown

Problem:OPTIONS:
- degradation
- life cycle
- ecosystem
- biodiversity

Answer the following question given this paragraph: Life on Earth is very diverse. The diversity of living things is called biodiversity . A measure of Earth's biodiversity is the number of different species of organisms that live on Earth. At least 10 million different species live on Earth today. They are commonly grouped into six different kingdoms. Examples of organisms within each kingdom are shown in Figure below . Q: What is the diversity of living things called? A:
****
A: biodiversity

Answer the following question given this paragraph: The dominant stage of the lifecycle of a fern is the sporophyte, which consists of large compound leaves called fronds. Fronds fulfill a double role; they are photosynthetic organs that also carry reproductive organs. The stem may be buried underground as a rhizome, from which adventitious roots grow to absorb water and nutrients from the soil; or, they may grow above ground as a trunk in tree ferns (Figure 25.20). Adventitious organs are those that grow in unusual places, such as roots growing from the side of a stem. Q: Which is the dominant stage of the lifecycle of a fern? A:
OPTIONS:
- gametophyte
- larvae
- zygote
- sporophyte
sporophyte

Answer the following question given this paragraph: The stomach also releases a very strong acid, called hydrochloric acid. This acid kills most pathogens that enter the stomach in food or water. Urine is also acidic, so few pathogens can grow in it. Q: What is the acid that is released by the stomach that kills most pathogens that enter the stomach? A:
OPTIONS:
- Nitric Acid
- Hydrofluoric Acid
- Sulfuric Acid
- hydrochloric acid

Answer: hydrochloric acid

input with options: Answer the following question given this paragraph: How Light-Dependent Reactions Work The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem. Photosystems exist in the membranes of thylakoids. A pigment molecule in the photosystem absorbs one photon, a quantity or "packet" of light energy, at a time. A photon of light energy travels until it reaches a molecule of chlorophyll. The photon causes an electron in the chlorophyll to become "excited. " The energy given to the electron allows it to break free from an atom of the chlorophyll molecule. Chlorophyll is therefore said to "donate" an electron (Figure 5.12). To replace the electron in the chlorophyll, a molecule of water is split. This splitting releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space. Technically, each breaking of a water molecule releases a pair of electrons, and therefore can replace two donated electrons. Q: The overall purpose of the light-dependent reactions is to convert light energy into this? A:
OPTIONS:
- photosynthesis
- thermal energy
- calories
- chemical reactions
output:
chemical reactions
