Q: What organ do mammals have that is exceptionally large for their body size? Read this paragraph and choose the correct option from the provided answers: Cerebral Cortex Compared to other vertebrates, mammals have exceptionally large brains for their body size. An entire alligator's brain, for example, would fill about one and a half teaspoons. This increase in brain to body size ratio is especially pronounced in apes, whales, and dolphins. While this increase in overall brain size doubtlessly played a role in the evolution of complex behaviors unique to mammals, it does not tell the whole story. Scientists have found a relationship between the relatively high surface area of the cortex and the intelligence and complex social behaviors exhibited by some mammals. This increased surface area is due, in part, to increased folding of the cortical sheet (more sulci and gyri). For example, a rat cortex is very smooth with very few sulci and gyri. Cat and sheep cortices have more sulci and gyri. Chimps, humans, and dolphins have even more. Choices: - lungs - heart - liver - brain A:
brain

Q: In the presence of oxygen, hydrogen can interact to make what? Read this paragraph and choose the correct option from the provided answers: A pile of leaves slowly rots in the backyard. In the presence of oxygen, hydrogen can interact to make water. Gold can be stretched into very thin wires. Choices: - carbon - helium - acid - water A:
water

Q: If only blue light strikes green leaves what happens to it? Read this paragraph and choose the correct option from the provided answers: The color of light that strikes an object may also affect the color that the object appears. For example, if only blue light strikes green leaves, the blue light is absorbed and no light is reflected. Choices: - it causes heating - it is reflected - it causes cooling - it is absorbed A:
it is absorbed

Each water molecule consists of two atoms of hydrogen (white) and one atom of oxygen (red). Choices: - alumhg and oxygen - One Hydrogen - Sodium and Oxygen - hydrogen and oxygen A:
hydrogen and oxygen
