input with options: Answer the following question given this paragraph: The answer is actually "no. " A virus is essentially DNA or RNA surrounded by a coat of protein ( Figure below ). It is not made of a cell , and cannot maintain a stable internal environment ( homeostasis ). Recall that a cell is the basic unit of living organisms. So if a virus is not made of at least one cell, can it be living? Viruses also cannot reproduce on their ownthey need to infect a host cell to reproduce. So a virus is very different from any of the organisms that fall into the three domains of life. Q: A virus is essentially dna or rna surrounded by a coat of what? A:
OPTIONS:
- acids
- paint
- organism
- protein
output: protein

Q: Answer the following question given this paragraph: This sperm is ready to penetrate the membrane of this egg. Notice the difference in size of the sperm and egg. Why is the egg so much larger? The egg contributes all the cytoplasm and organelles to the zygote. The sperm only contributes one set of chromosomes. Q: Which part of the reproductive process only contributes one set of chromosomes? A:

OPTIONS:
- ovum
- plasma
- egg
- sperm

A: sperm

input: OPTIONS:
- calcium
- carbonate
- nutrient
- chlorophyll Now, answer this question: Answer the following question given this paragraph: Figure 8.15 A photosystem consists of a light-harvesting complex and a reaction center. Pigments in the lightharvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced. In (a) photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product. In (b) photosystem I, the electron comes from the chloroplast electron transport chain discussed below. Q: In a photosystem, pigments in the light-harvesting complex pass light energy to two special molecules of what in the reaction center? A:
A:
output: chlorophyll

Q: Answer the following question given this paragraph: Particles that are too large to be suspended move along the stream bed by saltation. Q: What process allows particles too large to move along the stream bed? A:
Answer: saltation

Answer the following question given this paragraph: 31.3 Peripheral nervous system The peripheral nervous system is broken down into two sub-systems, the somatic nervous system and the autonomic nervous system. ANS - Autonomic Nervous System The ANS has two components - parasympathetic and sympathetic. The sympathetic nervous system is the "fight or flight" or fright response and results in an increased heart rate, increased rate of breathing, and an elevated blood glucose level. There is also decreased digestion. The second neurotransmitter is epinephrine. In this case, the first neuron is short and the second neuron is long. The parasympathetic nervous system is the rest and digest system. Drugs must be able to pass the blood brain barrier to have an effect on the CNS. Drugs act by affecting the neuron and how likely it is to fire an action potential. Stroke occurs when there is a blood clot that goes to the brain and prevent blood flow. Q: What are the two components of the autonomic nervous system? A:

OPTIONS:
- empathetic and sympathetic
- crystallisation and sympathetic
- neurons and sympathetic
- parasympathetic and sympathetic

Answer:
parasympathetic and sympathetic
