Answer the following question given this paragraph: Why are so many amphibian species threatened by extinction, and why should you care? The second question is easy. Amphibians control pests, may be a source of new medicines, and help feed many other animals. The nature of amphibian skin may help explain why so many amphibian species are at risk. Their skin easily absorbs substances from the environment, such as pollutants in water or air. Therefore, they may suffer from poor environmental quality before other animals do. As such, they may provide an early-warning system of environmental damage. Q: Which part of the body of amphibians, easily absorbs substances from the environment? A:
****
A: skin

Answer the following question given this paragraph: Alpha decay occurs when an unstable nucleus emits an alpha particle and energy. The diagram in Figure below represents alpha decay. An alpha particle contains two protons and two neutrons, giving it a charge of +2. A helium nucleus has two protons and two neutrons, so an alpha particle is represented in nuclear equations by the symbol . The superscript 4 is the mass number (2 protons + 2 neutrons). The subscript 2 is the charge of the particle as well as the number of protons. Q: What occurs when an unstable nucleus emits an alpha particle and energy? A:
OPTIONS:
- radar decay
- nucleus decay
- alpha radition
- alpha decay
alpha decay

Answer the following question given this paragraph: Strong bases completely dissociate in water, releasing all hydroxide anions into the solution. The most common strong bases are soluble metal hydroxides. Weak bases partially deprotonate water to form small amounts of hydroxide and the protonated base. Q: What kind of bases completely dissociate in water, releasing all hydroxide anions into the solution? A:
OPTIONS:
- unusual
- weak
- whole
- strong

Answer: strong

Question: Answer the following question given this paragraph: Centrioles are a very important part of centrosomes, which are involved in organizing microtubules in the cytoplasm. Centrosomes are associated with the nuclear membrane during prophase of the mitosis. In mitosis, the nuclear membrane breaks down and the microtubule organizing center (MTOC) of the centrosome arranges microtubules such that they interact with the chromosomes to build the mitotic spindle. Q: Centrioles are a very important part of what? A:
OPTIONS:
- centricles
- tubercles
- enterocytes
- centrosomes
Answer: centrosomes

input with options: Answer the following question given this paragraph: Melting ice and grinding wood into sawdust are examples of physical changes. Q: Melting ice and grinding wood into sawdust are examples of what? A:
OPTIONS:
- chemical changes
- reversible changes
- unpredictable changes
- physical changes
output: physical changes

Problem: OPTIONS:
- liquid nitrogen
- ice crystals
- carbonated ice
- solid carbon dioxide
Q: Answer the following question given this paragraph: Solid carbon dioxide is also called dry ice. That's because when it gets warmer and changes state, it doesn't change to a liquid by melting. Instead, it changes directly to a gas without going through the liquid state. The process in which a solid changes directly to a gas is called sublimation . It occurs when energy is added to a solid such as dry ice. You can watch dry ice changing directly to a gas in the video at this URL: http://www. youtube. com/watch?v=J8mDGwf-5x0 . Q: What is another term for dry ice? A:
Answer:
solid carbon dioxide
