Answer the following question given this paragraph: Nobody really has such colorful eyes! The colors were added digitally after the photo was taken. They represent all the different colors of light. Light is a form of energy that travels in waves. Light of different colors has different wavelengths. Q: Different colors of light differ in terms of which important attribute? Choices: - lenses - prisms - frequencies - wavelengths A:
wavelengths
Q: Answer the following question given this paragraph: Muscle tissue consists of cells that can contract, or shorten. Examples include skeletal muscle, which is attached to bones and makes them move. Other types of muscle include cardiac muscle, which makes the heart beat, and smooth muscle, which is found in other internal organs. Q: What kind of muscle is responsible for making the human heart beat? Choices: - deltoid - teres minor - respiratory muscle - cardiac muscle A:
A: cardiac muscle
Question: Answer the following question given this paragraph: In other covalent bonds, electrons are shared equally. These bonds are called nonpolar bonds. Neither atom attracts the shared electrons more strongly. As a result, the atoms remain neutral. Figure below shows an example of nonpolar bonds. Q: What is it called when electrons are shared equally? Choices: - polar bonds - helices bonds - metabolized bonds - nonpolar bonds A:
Answer: nonpolar bonds

Answer the following question given this paragraph: Figure 4.17 The chloroplast has an outer membrane, an inner membrane, and membrane structures called thylakoids that are stacked into grana. The space inside the thylakoid membranes is called the thylakoid space. The light harvesting reactions take place in the thylakoid membranes, and the synthesis of sugar takes place in the fluid inside the inner membrane, which is called the stroma. Chloroplasts also have their own genome, which is contained on a single circular chromosome. Q: Within the chloroplast, synthesis of what takes place in the fluid inside the inner membrane called the stroma? Choices: - fructose - wheat - glucose - sugar A:
**Answer**
sugar

Answer the following question given this paragraph: Nervous System Anosmia is the loss of the sense of smell. It is often the result of the olfactory nerve being severed, usually because of blunt force trauma to the head. The sensory neurons of the olfactory epithelium have a limited lifespan of approximately one to four months, and new ones are made on a regular basis. The new neurons extend their axons into the CNS by growing along the existing fibers of the olfactory nerve. The ability of these neurons to be replaced is lost with age. Age-related anosmia is not the result of impact trauma to the head, but rather a slow loss of the sensory neurons with no new neurons born to replace them. Smell is an important sense, especially for the enjoyment of food. There are only five tastes sensed by the tongue, and two of them are generally thought of as unpleasant tastes (sour and bitter). The rich sensory experience of food is the result of odor molecules associated with the food, both as food is moved into the mouth, and therefore passes under the nose, and when it is chewed and molecules are released to move up the pharynx into the posterior nasal cavity. Anosmia results in a loss of the enjoyment of food. As the replacement of olfactory neurons declines with age, anosmia can set in. Without the sense of smell, many sufferers complain of food tasting bland. Often, the only way to enjoy food is to add seasoning that can be sensed on the tongue, which usually means adding table salt. The problem with this solution, however, is that this increases sodium intake, which can lead to cardiovascular problems through water retention and the associated increase in blood pressure. Q: Anosmia, the loss of what sense, is often the result of the olfactory nerve being severed? Choices: - general sensitivity - taste - balance - smell A:
(Answer)
smell
