input: OPTIONS:
- atp
- ribosomes
- amino acid chains
- dna Now, answer this question: Answer the following question given this paragraph: Figure 17.5 Viruses can be complex in shape or relatively simple. This figure shows three relatively complex virions: the bacteriophage T4, with its DNA-containing head group and tail fibers that attach to host cells; adenovirus, which uses spikes from its capsid to bind to the host cells; and HIV, which uses glycoproteins embedded in its envelope to do so. Notice that HIV has proteins called matrix proteins, internal to the envelope, which help stabilize virion shape. HIV is a retrovirus, which means it reverse transcribes its RNA genome into DNA, which is then spliced into the host's DNA. (credit "bacteriophage, adenovirus": modification of work by NCBI, NIH; credit "HIV retrovirus": modification of work by NIAID, NIH). Q: Hiv is a retrovirus, which means it reverse transcribes its rna genome into what? A:
A:
output: dna

Answer the following question given this paragraph: Unlike nonvascular plants, all vascular plantsincluding seedless vascular plantshave a dominant sporophyte generation. Seedless vascular plants include clubmosses and ferns. Figure below shows a typical fern life cycle. Q: Do nonvascular or vascular plants have a dominant sporophyte generation? A:

OPTIONS:
- nonvascular
- deciduous
- perennial
- vascular

Answer: vascular

Problem: OPTIONS:
- freshwater biomes
- coastal biomes
- ocean dwellers
- marine biomes
Q: Answer the following question given this paragraph: Anglerfish live in the ocean. Aquatic biomes in the ocean are called marine biomes . Organisms that live in marine biomes must be adapted to the salt in the water. For example, many have organs for excreting excess salt. Two ocean zones are particularly challenging to marine organisms: the intertidal zone and the deep ocean. Q: What do you call aquatic biomes in the ocean? A:
Answer: marine biomes

Problem:OPTIONS:
- oxygen, carbon monoxide
- nitrogen, carbon dioxide
- oxygen, nitrogen
- oxygen, carbon dioxide

Answer the following question given this paragraph: User:helix84/Wikimedia Commons. Gas exchange is the movement of oxygen into the blood and carbon dioxide out of the blood . CC BY 2.5. Q: What gases move in and out of blood during gas exchange? A:
****
A: oxygen, carbon dioxide

Answer the following question given this paragraph: The jointed appendages of arthropods may be used as legs for walking. Being jointed makes them more flexible. Try walking or climbing stairs without bending your knees, and you'll see why joints are helpful. In most arthropods, the appendages on the head have been modified for other functions. Figure below shows some of the head appendages found in arthropods. Sensory organs such as eyes are also found on the head. Q: What may the jointed appendages of arthropods be used for? A:
OPTIONS:
- jumping
- crawling
- digging
- walking
walking

Answer the following question given this paragraph: A person is able to lift the entire rear end of the automobile using only one hand with the hydraulic jack shown in the image. Hydraulic systems are similar to simple machines in that they can produce very large mechanical advantages. Q: A hydraulic jack that makes it possible to lift a car easily is an example of what, meaning it produces mechanical advantages? A:
OPTIONS:
- quantum physics
- simple weapon
- complex machines
- simple machine

Answer:
simple machine
