Answer the following question given this paragraph: The back of the eye is covered by a thin layer called the retina. This is where the image of the object normally forms. The retina consists of special light-sensing cells called rods and cones. Rods sense dim light. Cones sense different colors of light. Q: The light-sensing cells in the retina are called rods and what else? Choices: - sensor cells - stents - light cells - cones A:
cones

Answer the following question given this paragraph: The lungs are the main organs of the respiratory system. This is where gases are exchanged between the air and the blood. Gases are also transported by the blood and exchanged between the blood and all the cells of the body. Q: What are the main organs of the respiratory system? Choices: - ovaries - intestines - kidneys - lungs A:
(Answer)
lungs
Ques: Answer the following question given this paragraph: Some children are born with genetic defects that are not carried by a single gene. Instead, an error in a larger part of the chromosome or even in an entire chromosome causes the disorder. Usually the error happens when the egg or sperm is forming. Having extra chromosomes or damaged chromosomes can cause disorders. Q: Having extra chromosomes or damaged chromosomes can cause what? Choices: - deformities - problems - diseases - disorders A:
Ans: disorders

(A).
wind
Ques:Answer the following question given this paragraph: The Menstrual Cycle Now that we have discussed the maturation of the cohort of tertiary follicles in the ovary, the build-up and then shedding of the endometrial lining in the uterus, and the function of the uterine tubes and vagina, we can put everything together to talk about the three phases of the menstrual cyclethe series of changes in which the uterine lining is shed, rebuilds, and prepares for implantation. The timing of the menstrual cycle starts with the first day of menses, referred to as day one of a woman's period. Cycle length is determined by counting the days between the onset of bleeding in two subsequent cycles. Because the average length of a woman's menstrual cycle is 28 days, this is the time period used to identify the timing of events in the cycle. However, the length of the menstrual cycle varies among women, and even in the same woman from one cycle to the next, typically from 21 to 32 days. Just as the hormones produced by the granulosa and theca cells of the ovary "drive" the follicular and luteal phases of the ovarian cycle, they also control the three distinct phases of the menstrual cycle. These are the menses phase, the proliferative phase, and the secretory phase. Q: The average length of a woman's menstrual cycle is what? Choices: - 19 days - 16 days - 5 days - 28 days A:

Ans:28 days
Answer the following question given this paragraph: There are other units in chemistry that are important, and we will cover others in the course of the entire book. One of the fundamental quantities in science is temperature. Temperature is a measure of the average amount of energy of motion, or kinetic energy, a system contains. Temperatures are expressed using scales that use units called degrees, and there are several temperature scales in use. In the United States, the commonly used temperature scale is the Fahrenheit scale (symbolized by F and spoken as "degrees Fahrenheit"). On this scale, the freezing point of liquid water (the temperature at which liquid water turns to solid ice) is 32F, and the boiling point of water (the temperature at which liquid water turns to steam) is 212F. Science also uses other scales to express temperature. The Celsius scale (symbolized by C and spoken as "degrees Celsius") is a temperature scale where 0C is the freezing point of water and 100C is the boiling point of water; the scale is divided into 100 divisions between these two landmarks and extended higher and lower. By comparing the Fahrenheit and Celsius scales, a conversion between the two scales can be determined: C=(F32)59 Saylor URL: http://www. saylor. org/books.
