Question: Answer the following question given this paragraph:   Nucleic acids are biochemical compounds that include RNA (ribonucleic acid) and DNA (deoxyribonucleic acid). Nucleic acids consist of chains of small molecules called nucleotides. Nucleotides are the monomers of nucleic acids. A nucleotide is shown in Figure below .   Q: What consist of chains of small molecules called nucleotides?   A:

OPTIONS:
- Atomic acids
- structural acids
- nitrous acids
- nucleic acids

Answer: nucleic acids

Problem: OPTIONS:
- the vagina
- the cervix
- the ovaries
- the placenta
Q: Answer the following question given this paragraph:   The placenta permits a long period of fetal growth in the uterus. As a result, the fetus can become large and mature before birth. This increases its chances of surviving.   Q: What allows for a large and mature fetus before birth,  resulting from a long period of fetal growth in the uterus?   A:
Answer: the placenta

Problem:OPTIONS:
- ionosphere
- stratosphere
- gravitational field
- magnetic field

Answer the following question given this paragraph:   Earth's magnetosphere is controlled by the magnetic field. The magnetosphere protects the planet from the solar wind . The solar wind is ions that fly from the Sun to Earth very fast. The magnetosphere protects Earth's ozone layer. So life on Earth needs the protection of the magnetosphere.   Q: What controls earth's magnetosphere?   A:
****
A: magnetic field

Answer the following question given this paragraph:   When waves of two different frequencies interfere, a phenomenon known as beating occurs. The frequency of a beat is the difference of the two frequencies.   Q: When waves of two different frequencies interfere, what phenomenon occurs?   A:
OPTIONS:
- making
- opening
- soaking
- beating
beating

Answer the following question given this paragraph:   Morphology of Sponges The morphology of the simplest sponges takes the shape of a cylinder with a large central cavity, the spongocoel, occupying the inside of the cylinder. Water can enter into the spongocoel from numerous pores in the body wall. Water entering the spongocoel is extruded via a large common opening called the osculum. However, sponges exhibit a range of diversity in body forms, including variations in the size of the spongocoel, the number of osculi, and where the cells that filter food from the water are located. While sponges (excluding the hexactinellids) do not exhibit tissue-layer organization, they do have different cell types that perform distinct functions. Pinacocytes, which are epithelial-like cells, form the outermost layer of sponges and enclose a jelly-like substance called mesohyl. Mesohyl is an extracellular matrix consisting of a collagen-like gel with suspended cells that perform various functions. The gel-like consistency of mesohyl acts like an endoskeleton and maintains the tubular morphology of sponges. In addition to the osculum, sponges have multiple pores called ostia on their bodies that allow water to enter the sponge. In some sponges, ostia are formed by porocytes, single tube-shaped cells that act as valves to regulate the flow of water into the spongocoel. In other sponges, ostia are formed by folds in the body wall of the sponge. Choanocytes (“collar cells”) are present at various locations, depending on the type of sponge, but they always line the inner portions of some space through which water flows (the spongocoel in simple sponges, canals within the body wall in more complex sponges, and chambers scattered throughout the body in the most complex sponges). Whereas pinacocytes line the outside of the sponge, choanocytes tend to line certain inner portions of the sponge body that surround the mesohyl. The structure of a choanocyte is critical to its function, which is to generate a water current through the sponge and to trap and ingest food particles by...   Q: What is another name for collar cells?   A:
OPTIONS:
- enzymes
- sporozoans
- clutches
- choanocytes

Answer: choanocytes

input with options: Answer the following question given this paragraph:   Anaerobic prokaryotes do not need oxygen. They use fermentation or other methods of respiration that don’t require oxygen. In fact, some cannot tolerate oxygen. An example is a bacterium that infects wounds and kills tissues, causing a condition called gangrene.   Q: What do you call prokaryotes that do not need oxygen for respiration?   A:
OPTIONS:
- aerobic
- chloroflexus
- enzymatic
- anaerobic
output:
Answer: anaerobic
