Answer the following question given this paragraph: The brains of all mammals have a unique layer of nerve cells covering the cerebrum. This layer is called the neocortex (the pink region of the brains in Figure above ). The neocortex plays an important role in many complex brain functions. In some mammals, such as rats, the neocortex is relatively smooth. In other mammals, especially humans, the neocortex has many folds. The folds increase the surface area of the neocortex. The larger this area is, the greater the mental abilities of an animal. Q: What is the unique layer of nerve cells covering the cerebrum in mammals' brains called? Choices: - the midbrain - the neural - cerebral cortex - the neocortex A:
the neocortex
Answer the following question given this paragraph: RNA consists of just one chain of nucleotides. DNA consists of two chains. Nitrogen bases on the two chains of DNA form hydrogen bonds with each other. Hydrogen bonds are relatively weak bonds that form between a positively charged hydrogen atom in one molecule and a negatively charged atom in another molecule. Hydrogen bonds form only between adenine and thymine, and between guanine and cytosine. These bonds hold the two chains together and give DNA is characteristic double helix, or spiral, shape. Q: What has two chains of nucleotides, one more than rna? Choices: - gna - fna - mna - dna A:
dna
Q: Answer the following question given this paragraph: Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not. Q: Solutions of ionic compounds and melted ionic compounds conduct what? Choices: - radiation - sound waves - light - electricity A:
A: electricity
Question: Answer the following question given this paragraph: Monosaccharides can be linked together to form disaccharides or polysaccharides. Q: What can be linked together to form disaccharides or polysaccharides? Choices: - amino acids - carbohydrates - nitrates - monosaccharides A:
Answer: monosaccharides

Answer the following question given this paragraph: You can see several examples of people or things in motion in Figure below . You can probably think of many other examples. You know from experience what motion is, so it may seem like a straightforward concept. Motion can also be defined simply, as a change in position. But if you think about examples of motion in more depth, you'll find that the idea of motion is not quite as simple and straightforward as it seems. Q: What can be defined simply, as a change in position? Choices: - velocity - gravity - speed - motion A:
**Answer**
motion

Answer the following question given this paragraph: Diseases of the nervous system include infections, epilepsy, strokes, and Alzheimer's disease. Injuries include concussions and spinal cord damage that may cause paralysis. Most nervous system diseases can't be prevented, but many nervous system injuries can be prevented by following safe practices. Q: Diseases of this system include epilepsy, strokes, and alzheimer's disease Choices: - infectious system - circulatory system - endocrine system - nervous system A:
(A).
nervous system
