input: OPTIONS:
- dermis
- layers
- Skin
- epidermis Now, answer this question: Answer the following question given this paragraph: This tissue includes several types of specialized cells. Pavement cells, large, irregularly shaped parenchymal cells which lack chloroplasts, make up the majority of the epidermis. Within the epidermis, thousands of pairs of bean-shaped schlerenchymal guard cells swell and shrink by osmosis to open and close stomata , tiny pores which control the exchange of oxygen and carbon dioxide gases and the release of water vapor. The lower surfaces of some leaves contain as many as 100,000 stomata per square centimeter. Q: Pavement cells, large, irregularly shaped parenchymal cells which lack chloroplasts, make up the majority of what? A:
A:
output: epidermis

Answer the following question given this paragraph: Q: If environmental conditions deteriorate, many species can form protective what? A:

OPTIONS:
- fibers
- proteins
- shells
- cysts

Answer: cysts

Problem: OPTIONS:
- the sudden response
- the asymptomatic response
- the malignant response
- the immune response
Q: Answer the following question given this paragraph: Like the immune systems of other vertebrates, the human immune system is adaptive. If pathogens manage to get through the body's first two lines of defense, the third line of defense takes over. The third line of defense is referred to as the immune response . This defense is specific to a particular pathogen, and it allows the immune system to "remember" the pathogen after the infection is over. If the pathogen tries to invade the body again, the immune response against that pathogen will be much faster and stronger. Q: The third line of defense of the immune system is called? A:
Answer: the immune response

Problem:OPTIONS:
- the seager hypothesis
- Big Bang theory
- small world theory
- the gaia hypothesis

Answer the following question given this paragraph: The Gaia hypothesis states that the biosphere is its own living organism. Q: What hypothesis states that the biosphere is its own living organism A:
****
A: the gaia hypothesis

Answer the following question given this paragraph: Bases are ionic compounds that produce negative hydroxide ions (OH - ) when dissolved in water. An ionic compound contains positive metal ions and negative nonmetal ions held together by ionic bonds. (Ions are atoms that have become charged particles because they have either lost or gained electrons. ) An example of a base is sodium hydroxide (NaOH). When it dissolves in water, it produces negative hydroxide ions and positive sodium ions (Na + ). This can be represented by the equation:. Q: What are the ionic compounds that produce negative hydroxide ions when dissolved in water? A:
OPTIONS:
- isotopes
- acids
- enzymes
- bases
bases

Answer the following question given this paragraph: The cell wall is located outside the cell membrane. It consists mainly of cellulose and may also contain lignin, which makes it more rigid. The cell wall shapes, supports, and protects the cell. It prevents the cell from absorbing too much water and bursting. It also keeps large, damaging molecules out of the cell. Q: Where is the cell wall located? A:
OPTIONS:
- in cell membrane
- in the chloroplast
- in the mitochondria
- outside cell membrane

Answer:
outside cell membrane
