Question: Answer the following question given this paragraph: Mass spectrometry today is used extensively in chemistry and biology laboratories to identify chemical and biological substances according to their mass-to-charge ratios. In medicine, mass spectrometers are used to measure the concentration of isotopes used as tracers. Usually, biological molecules such as proteins are very large, so they are broken down into smaller fragments before analyzing. Recently, large virus particles have been analyzed as a whole on mass spectrometers. Sometimes a gas chromatograph or high-performance liquid chromatograph provides an initial separation of the large molecules, which are then input into the mass spectrometer. Q: Mass spectrometry today is used extensively in chemistry and biology laboratories to identify chemical and biological substances according to their ratios of what? A:
OPTIONS:
- ph to charge
- volume to charge
- mass to volume
- mass-to-charge
Answer: mass-to-charge

input with options: Answer the following question given this paragraph: Many animals go through daily cycles. Daily cycles of behavior are called circadian rhythms. For example, most animals go to sleep when the sun sets down and wake up when the sun rises. These animals are active during the day and called diurnal. Other animals go to sleep when the sun rises and wake up when the sun sets. These animals are active during the night and called nocturnal. Many owls, like the owls in Figure below , are nocturnal. Like some other nocturnal animals, they have large eyes that are specially adapted for seeing when light levels are low. Q: What term refers to an animal that sleeps during the day and is active at night? A:
OPTIONS:
- diurnal
- crepuscular
- solitary
- nocturnal
output: nocturnal

Q: Answer the following question given this paragraph: Populations of viruses do not grow through cell division because they are not cells. Instead, they use the machinery and metabolism of a host cell to produce new copies of themselves. After infecting a host cell, a virion uses the cell's ribosomes, enzymes, ATP, and other components to replicate. Viruses vary in how they do this. For example:. Q: Populations of viruses do not grow through cell division because they? A:

OPTIONS:
- Static
- Acidic
- non living
- are not cells

A: are not cells

input: OPTIONS:
- nucleus
- fetus
- gamete
- embryo Now, answer this question: Answer the following question given this paragraph: Q: Endosperm usually develops before the what does? A:
A:
output: embryo

Answer the following question given this paragraph: Men and women share most of the same organs. We all have skin, a heart, and lungs. Men and women differ only in their reproductive organs. Q: What organ system is different in men and women? A:

OPTIONS:
- nervous organs
- respratory organs
- lymphatic organs
- reproductive organs

Answer: reproductive organs

Q: Answer the following question given this paragraph: Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Although the kidneys are the main organs of excretion, several other organs also excrete wastes. They include the large intestine, liver, skin, and lungs. All of these organs of excretion, along with the kidneys, make up the excretory system . The roles of the excretory organs other than the kidney are summarized below:. Q: What is the process of removing wastes and excess water from the body called? A:

OPTIONS:
- inspiration
- ingestion
- diffusion
- excretion

A:
excretion
