Answer the following question given this paragraph: Peripheral membrane proteins are proteins that are only temporarily associated with the membrane. They can be easily removed, which allows them to be involved in cell signaling. Peripheral proteins can also be attached to integral membrane proteins, or they can stick into a small portion of the lipid bilayer by themselves. Peripheral membrane proteins are often associated with ion channels and transmembrane receptors. Most peripheral membrane proteins are hydrophilic. Q: What type of proteins are only temporarily associated with the membrane? A:

OPTIONS:
- visual membrane proteins
- sensitive rod proteins
- peripheral oxidation proteins
- peripheral membrane proteins

Answer: peripheral membrane proteins

Problem: OPTIONS:
- shell electrons
- outer electrons
- positive electrons
- valence electrons
Q: Answer the following question given this paragraph: The electrons in the outer energy level of an atom are called valence electrons . It is valence electrons that are potentially involved in chemical reactions. The number of valence electrons determines an element's reactivity, or how likely the element is to react with other elements. The number of valence electrons also determines whether the element can conduct electric current. That's because electric current is the flow of electrons. Table below shows how these properties vary in elements from each class. Q: What are electrons in the outer energy level of an atom called? A:
Answer: valence electrons

Problem:OPTIONS:
- spore
- pathogen
- egg
- pollen

Answer the following question given this paragraph: Wind-blown pollen might land anywhere and be wasted. Another adaptation solved this problem. Plants evolved traits that attract specific animal pollinators . Like the bee in Figure below , a pollinator picks up pollen on its body and carries it directly to another plant of the same species. This greatly increases the chance that fertilization will occur. Q: What does a pollinator pick from its body and carry directly to another plant of the same species? A:
****
A: pollen

Answer the following question given this paragraph: The largest known virus, called mimivirus, is so large that scientists first mistook it for a bacterium. It was first discovered in amoeba, in 1992, and was identified as a virus in 2003. Scientists believe that mimivirus may cause certain types of pneumonia in humans. The core contains DNA, with the majority of the DNA in genes, and only 10% DNA of unknown function ("junk" DNA). Q: What is the largest known virus? A:
OPTIONS:
- polyomavirus
- influenza virus
- pneumonia virus
- mimivirus
mimivirus

Answer the following question given this paragraph: The melting point of a substance is the temperature that separates a solid and a liquid. The boiling point of a substance is the temperature that separates a liquid and a gas. What accounts for this variability? Why do some substances become liquids at very low temperatures, while others require very high temperatures before they become liquids? It all depends on the strength of the intermolecular interactions between the particles of substances. (Although ionic compounds are not composed of discrete molecules, we will still use the term intermolecular to include interactions between the ions in such compounds. ) Substances that experience strong intermolecular interactions require higher temperatures to become liquids and, finally, gases. Substances that experience weak intermolecular interactions do not need much energy (as measured by Saylor URL: http://www. saylor. org/books. Q: Melting points are temperatures that are high enough to separate liquids from which substances? A:
OPTIONS:
- gases
- seeds
- oils
- solids

Answer: solids

input with options: Answer the following question given this paragraph: When it comes to energy, ecosystems are not closed. They need constant inputs of energy. Most ecosystems get energy from sunlight. A small minority get energy from chemical compounds. Unlike energy, matter is not constantly added to ecosystems. Instead, it is recycled. Water and elements such as carbon and nitrogen are used over and over again. Q: What do most ecosystems get energy from? A:
OPTIONS:
- magma
- moisture
- evaporation
- sunlight
output:
sunlight
