Answer the following question given this paragraph: Then, as now, giraffes fed on tree leaves. Perhaps the environment changed, and leaves became scarcer. There would be more giraffes than the trees could support. Thus, there would be a "struggle for existence. ". Q: Are giraffes herbivores or are they omnivores? Choices: - neither - carnivores - omnivores - herbivores A:
herbivores

Answer the following question given this paragraph: Homeostasis refers to the balance, or equilibrium within the cell or a body. It is an organism's ability to keep a constant internal environment. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is called homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the set point (the normal level or range). Homeostasis is a dynamic equilibrium rather than an unchanging state. The cellular processes discussed in this lesson all play an important role in homeostatic regulation. More concerning homeostasis will be presented in additional concepts. Q: What is the name of the process that refers to the balance or equilibrium within the cell or a body? Choices: - static - hypothesis - determinants - homeostasis A:
(Answer)
homeostasis
Ques: Answer the following question given this paragraph: It's rare for a biologist to predict the discovery of a new species. For his prediction, Kavanaugh drew inspiration from Darwin's own 1862 prediction. When Darwin observed an orchid from Madagascar with a foot-long nectar, he predicted that a pollinator would be found with a tongue long enough to reach the nectar inside the orchid's very thin, elongated nectar ''pouch'', though he had never seen such a bird or insect. Darwin's prediction was based on his finding that all species are related to each other and that some of them evolve together, developing similar adaptations . Darwin's prediction came true in 1903, when a moth was discovered in Madagascar with a long, thin proboscis, which it uncurls to reach the nectar in the orchid's nectar. In the process of feeding from the orchid, the moth serves as its pollinator. The moth was given the scientific name Xanthopan morganii praedicta , in honor of Darwin's prediction. Q: Darwin found that, since all species are related to each other and some of them evolve together, so they develop similar what? Choices: - appearance - language - systems - adaptations A:
Ans: adaptations

Answer the following question given this paragraph: A camp fire is an example of basic thermochemistry. The reaction is initiated by the application of heat from a match. The reaction converting wood to carbon dioxide and water (among other things) continues, releasing heat energy in the process. This heat energy can then be used to cook food, roast marshmallows, or just keep warm when it's cold outside. Q: What kind of energy is released when the thermochemical reaction of a campfire converts wood to carbon dioxide and water? Choices: - ultraviolet - light - smoke - heat A:
(A).
heat
Ques:Answer the following question given this paragraph: Figure 7.5 Lateral View of Skull The lateral skull shows the large rounded brain case, zygomatic arch, and the upper and lower jaws. The zygomatic arch is formed jointly by the zygomatic process of the temporal bone and the temporal process of the zygomatic bone. The shallow space above the zygomatic arch is the temporal fossa. The space inferior to the zygomatic arch and deep to the posterior mandible is the infratemporal fossa. Q: What is the term for the shallow space above the zygomatic arch in a skull? Choices: - angular fossa - distinct fossa - Medium Fossa - temporal fossa A:

Ans:temporal fossa
Answer the following question given this paragraph: Light has properties of both a wave and a particle. Q: Light has the properties of both a wave and what else? Choices: - atom - nucleus - electron - particle A:
particle
