Answer the following question given this paragraph: Physics also tells us that, although energy can be captured or transformed, it inevitably degrades, becoming heat, a less useful form of energy. This is why organisms require a constant input of energy; the work they must do uses up the energy they take in. Energy, unlike materials, cannot be recycled. The story of life is a story of energy flow its capture, transformation, use for work, and loss as heat. Q: When energy is captured or transformed, it inevitably degrades and becomes what less useful form of energy? Choices: - chemical - temperature - motion - heat A:
heat

Answer the following question given this paragraph: Like hurricanes, winter storms develop from cyclones. But in the case of winter storms, the cyclones form at higher latitudes. In North America, cyclones often form when the jet stream dips south in the winter. This lets dry polar air pour south. At the same time, warm moist air from the Gulf of Mexico flows north. When the two air masses meet, the differences in temperature and pressure cause strong winds and heavy precipitation. Two types of winter storms that occur in the U. S. are blizzards and lake-effect snow storms. Q: Winter storms develop from what, which form at high altitudes and are associated with hurricanes as well? Choices: - fronts - currents - droughts - cyclones A:
(Answer)
cyclones

Saylor URL: http://www. saylor. org/books. Q: The name carbon tetrachloride implies one carbon atom and four of which other atoms? Choices: - calcium - nitrogen - iodine - chlorine A:
Ans: chlorine
(Q).
Answer the following question given this paragraph: Eukaryotes evolved about 2 billion years ago. Unlike prokaryotes, eukaryotes have a cell nucleus. They have more structures and are better organized. Organelles within a eukaryote can perform certain functions. Some supply energy; some break down wastes. Eukaryotes were better able to live and so became the dominant life form. You can see an example of a eukaryotic cell below ( Figure below ). Q: Unlike prokaryotes, eukaryotes have a what? Choices: - flagellum - cell wall - mitochondria - cell nucleus A:
(A).
cell nucleus
Ques:Answer the following question given this paragraph: One way early land invertebrates solved these problems was with an exoskeleton. This is a non-bony skeleton that forms on the outside of the body. It supports the body and helps it retain water. As the organism grows, it sheds its old exoskeleton and grows a new one. Figure below shows the discarded exoskeleton of a dragonfly. Q: A non-bony skeleton that forms outside of the body is known as a what? Choices: - excitoskeleton - exoplate - endoskeleton - exoskeleton A:

Ans:exoskeleton
Ques:Answer the following question given this paragraph: Gravity has traditionally been defined as a force of attraction between things that have mass. The strength of gravity between two objects depends on their mass and their distance apart. Q: What is the force of attraction between things that have mass Choices: - friction - motion - momentum - gravity A:

Ans:
gravity
