Answer the following question given this paragraph: Basal Ganglia Interconnected brain areas called the basal ganglia (or basal nuclei), shown in Figure 35.20b, play important roles in movement control and posture. Damage to the basal ganglia, as in Parkinson's disease, leads to motor impairments like a shuffling gait when walking. The basal ganglia also regulate motivation. For example, when a wasp sting led to bilateral basal ganglia damage in a 25-year-old businessman, he began to spend all his days in bed and showed no interest in anything or anybody. But when he was externally stimulatedas when someone asked to play a card game with himhe was able to function normally. Interestingly, he and other similar patients do not report feeling bored or frustrated by their state. Thalamus The thalamus (Greek for "inner chamber"), illustrated in Figure 35.24, acts as a gateway to and from the cortex. It receives sensory and motor inputs from the body and also receives feedback from the cortex. This feedback mechanism can modulate conscious awareness of sensory and motor inputs depending on the attention and arousal state of the animal. The thalamus helps regulate consciousness, arousal, and sleep states. A rare genetic disorder called fatal familial insomnia causes the degeneration of thalamic neurons and glia. This disorder prevents affected patients from being able to sleep, among other symptoms, and is eventually fatal. Q: What helps to regulate consciousness, arousal, and sleep states? Choices: - hypothalamus - hippocampus - cerebral cortex - thalamus A:
thalamus

Answer the following question given this paragraph: Imagine that you are a scientist. While collecting water samples at a local pond, you notice a frog with five legs instead of four ( Figure below ). As you start to look around, you discover that many of the frogs have extra limbs, extra eyes, or no eyes. One frog even has limbs coming out of its mouth. These are your observations , or things you notice about an environment using your five senses. Q: In terms of scientific investigation, things you notice about an environment using your five senses are called what? Choices: - evidence - behaviors - patterns - observations A:
(Answer)
observations
Ques: Answer the following question given this paragraph: precision: A measure of how close a series of measurements are to one another. Precise measurements are highly reproducible, even if the measurements are not near the correct value. Q: A measure of how close a series of measurements are to one another is what? Choices: - calculation - density - reflection - precision A:
Ans: precision
(Q).
Answer the following question given this paragraph: The top layer of water farther from shore is called the limnetic zone. There is enough light for photosynthesis and plenty of dissolved oxygen. However, dissolved nutrients tend not to be as plentiful as they are in the littoral zone. Producers here are mainly phytoplankton. A variety of zooplankton and fish also occupy this zone. Q: What is the top layer of water farther from shore called? Choices: - Tidal Zone - semimetal zone - Beach Zone - limnetic zone A:
(A).
limnetic zone
Ques:Answer the following question given this paragraph: Scientists usually begin an investigation with facts. A fact is a bit of information that is true. Facts come from data collected from observations. Facts can also come from experiments that have been run. Data is factual information that results from an investigation. Facts and data are not subject to opinion or bias. An opinion is someone's subjective view or position on a subject. Q: In science, what is a bit of information that is true? Choices: - lie - theory - falsehood - a fact A:

Ans:a fact
Answer the following question given this paragraph: Cell division is just one of several stages that a cell goes through during its lifetime. The cell cycle is a repeating series of events that include growth, DNA synthesis, and cell division. The cell cycle in prokaryotes is quite simple: the cell grows, its DNA replicates, and the cell divides. In eukaryotes, the cell cycle is more complicated. Q: What is defined as a repeating series of events that include growth, dna synthesis, and cell division? Choices: - photosynthesis - meiosis - puberty - cell cycle A:
cell cycle
