Q: Answer the following question given this paragraph: The 24 human chromosomes. The autosomes are numbered 1 - 22, based on size, with chromosome 1 being the largest. The X and Y sex chromosomes are shown in the box. Q: X and y are the labels of what specialized human chromosomes? A:

OPTIONS:
- carb chromosomes
- exotic chromosomes
- protein chromosomes
- sex chromosomes

A: sex chromosomes

input: OPTIONS:
- staurikosaurus
- mitochondria
- sporozoans
- gnetophytes Now, answer this question: Answer the following question given this paragraph: Gnetophytes Gnetophytes are the closest relatives to modern angiosperms, and include three dissimilar genera of plants. Like angiosperms, they have broad leaves. Gnetum species are mostly vines in tropical and subtropical zones. The single species of Welwitschia is an unusual, low-growing plant found in the deserts of Namibia and Angola. It may live for up to 2000. Q: What are the closest relatives to modern angiosperms? A:
A:
output: gnetophytes

OPTIONS:
- insects
- reptiles
- mammals
- amphibians

Answer: amphibians

Problem: OPTIONS:
- unbalanced

- exothermic
Q: Answer the following question given this paragraph: Summary Changes of state are examples of phase changes, or phase transitions. All phase changes are accompanied by changes in the energy of a system. Changes from a more-ordered state to a less-ordered state (such as a liquid to a gas) areendothermic. Changes from a less-ordered state to a more-ordered state (such as a liquid to a solid) are always exothermic. The conversion of a solid to a liquid is called fusion (or melting). The energy required to melt 1 mol of a substance is its enthalpy of fusion (Hfus). The energy change required to vaporize 1 mol of a substance is the enthalpy of vaporization (Hvap). The direct conversion of a solid to a gas is sublimation. The amount of energy needed to sublime 1 mol of a substance is its enthalpy of sublimation (Hsub) and is the sum of the enthalpies of fusion and vaporization. Plots of the temperature of a substance versus heat added or versus heating time at a constant rate of heating are calledheating curves. Heating curves relate temperature changes to phase transitions. A superheated liquid, a liquid at a temperature and pressure at which it should be a gas, is not stable. A cooling curve is not exactly the reverse of the heating curve because many liquids do not freeze at the expected temperature. Instead, they form a supercooled liquid, a metastable liquid phase that exists below the normal melting point. Supercooled liquids usually crystallize on standing, or adding a seed crystal of the same or another substance can induce crystallization. Q: Changes from a less-ordered state to a more-ordered state (such as a liquid to a solid) are always what? A:
Answer: exothermic

Problem:OPTIONS:
- absorption
- excretion
- regeneration
- digestion

****
A: digestion

Problem:OPTIONS:
- unnatural science
- natural science
- negative science
- physical science

Answer the following question given this paragraph: Physical science is the study of matter and energy. That covers a lot of territory because matter refers to all the "stuff" that exists in the universe. It includes everything you can see and many things that you cannot see, including the air around you. Energy is also universal. It's what gives matter the ability to move and change. Electricity, heat, and light are some of the forms that energy can take. Q: What branch of science is the study of matter and energy? A:
****
A:
physical science
