Answer the following question given this paragraph: Phospholipids As its name suggests, a phospholipid is a bond between the glycerol component of a lipid and a phosphorous molecule. In fact, phospholipids are similar in structure to triglycerides. However, instead of having three fatty acids, a phospholipid is generated from a diglyceride, a glycerol with just two fatty acid chains (Figure 2.23). The third binding site on the glycerol is taken up by the phosphate group, which in turn is attached to a polar "head" region of the molecule. Recall that triglycerides are nonpolar and hydrophobic. This still holds for the fatty acid portion of a phospholipid compound. However, the head of a phospholipid contains charges on the phosphate groups, as well as on the nitrogen atom. These charges make the phospholipid head hydrophilic. Therefore, phospholipids are said to have hydrophobic tails, containing the neutral fatty acids, and hydrophilic heads, containing the charged phosphate groups and nitrogen atom. Q: A phospholipid is a bond between the glycerol component of a lipid and what else? Choices: - chlorine molecule - elemental molecule - oxygen molecule - phosphorous molecule A:
(Answer)
phosphorous molecule

Answer the following question given this paragraph: Symbiosis is a close relationship between organisms of different species in which at least one of the organisms benefits. The other organism may also benefit, or it may be unaffected or harmed by the relationship. Figure below shows an example of symbiosis. The birds in the picture are able to pick out food from the fur of the deer. The deer won't eat the birds. In fact, the deer knowingly lets the birds rest on it. What, if anything, do you think the deer gets out of the relationship?. Q: What's the term for a relationship between two organisms where at least one benefits? Choices: - dermatitis - morphogenesis - meiosis - symbiosis A:
(A).
symbiosis

Q: Which waves have the longest wavelengths but the least energy in the atmosphere? Choices: - microwaves - channel waves - light waves - radio waves A:

Ans:radio waves
Answer the following question given this paragraph: Another obvious change that occurs during puberty is rapid growth. This is called the adolescent growth spurt . In boys, it is controlled by testosterone. The rate of growth usually starts to increase relatively early in puberty. At its peak rate, growth in height is about 10 centimeters (almost 4 inches) per year in the average male. Growth generally remains rapid for several years. Growth and development of muscles occur toward the end of the growth spurt in height. Muscles may continue to develop and gain strength after growth in height is finished. Q: What drives puberty in male humans? Choices: - bloodstream - estrogen - methane - testosterone A:
testosterone
