Answer the following question given this paragraph: into the brain, and the posterior region becomes the spinal cord. Tissues at the edges of the neural groove, when it closes off, are called the neural crest and migrate through the embryo to give rise to PNS structures as well as some non-nervous tissues. The brain develops from this early tube structure and gives rise to specific regions of the adult brain. As the neural tube grows and differentiates, it enlarges into three vesicles that correspond to the forebrain, midbrain, and hindbrain regions of the adult brain. Later in development, two of these three vesicles differentiate further, resulting in five vesicles. Those five vesicles can be aligned with the four major regions of the adult brain. The cerebrum is formed directly from the telencephalon. The diencephalon is the only region that keeps its embryonic name. The mesencephalon, metencephalon, and myelencephalon become the brain stem. The cerebellum also develops from the metencephalon and is a separate region of the adult brain. The spinal cord develops out of the rest of the neural tube and retains the tube structure, with the nervous tissue thickening and the hollow center becoming a very small central canal through the cord. The rest of the hollow center of the neural tube corresponds to open spaces within the brain called the ventricles, where cerebrospinal fluid is found. Q: The brain develops from this early tube structure and gives rise to specific regions of the adult brain. as the neural tube grows and differentiates, it enlarges into three vesicles that correspond to the forebrain, midbrain, and this? Choices: - anteriorbrain - rearbrain - astrobrain - hindbrain A:
hindbrain

Answer the following question given this paragraph: Renewable resources can be renewed as they are used. An example is timber, which comes from trees. New trees can be planted to replace those that are cut down. Sunlight is a renewable resource. It seems we will never run out of that!. Q: Timber, obtained from trees that can be replanted to replace those that are cut down, is an example of what type of resource? Choices: - nonrenewable - fossil fuel - mineral - renewable A:
(Answer)
renewable
Ques: Answer the following question given this paragraph: Some species of animals are territorial . This means that they defend their area. The area they defend usually contains their nest and enough food for themselves and their offspring. A species is more likely to be territorial if there is not very much food in their area. Animals generally do not defend their territory by fighting. Instead, they are more likely to use display behavior. The behavior tells other animals to stay away. It gets the message across without the need for fighting. Display behavior is generally safer and uses less energy than fighting. Male gorillas use display behavior to defend their territory. They pound on their chests and thump the ground with their hands to warn other male gorillas to keep away from their area. The robin displays his red breast to warn other robins to stay away ( Figure below ). Q: Animals that defend their area are generally known as what kinds of animals? Choices: - mutants - neutral - carnivores - territorial A:
Ans: territorial

Answer the following question given this paragraph: Many thermometers measure temperature with a liquid that expands when it gets warmer and contracts when it gets cooler. Look at the common household thermometer pictured in the Figure below . The red liquid rises or falls in the glass tube as the temperature changes. Temperature is read off the scale at the height of the liquid in the tube. To learn more about measuring temperature, watch the animation "Measuring Temperature" at this URL: http://www. sciencehelpdesk. com/unit/science2/3. Q: How does the liquid in a thermometer respond to heat or cold? Choices: - freezes or boils - disappears - rises or vaporizes - expands or contracts A:
(A).
expands or contracts
Ques:Answer the following question given this paragraph: Genes play an important part in determining our adult height. However, factors such as poor nutrition can prevent us from achieving our full genetic potential. Q: What factor other than genes is important in determining adult height? Choices: - intelligence - cultivation - relaxation - nutrition A:

Ans:nutrition
Answer the following question given this paragraph: Q: During diastole, what happens to the elastic walls of the arteries? Choices: - they expand - they become hardened - they evolve - they snap back A:
