Q: What type of disease is muscular dystrophy? Read this paragraph and choose the correct option from the provided answers: Muscular dystrophy is a term encompassing a variety of muscle wasting diseases. The most common type, Duchenne Muscular Dystrophy (DMD) , affects cardiac and skeletal muscle, as well as some mental functions. DMD is caused by a defective gene for dystrophin, a protein prevalent in skeletal and cardiac muscles. DMD is an X-linked recessive disorder occurring in 1 in 3,500 male newborns. Because DMD is X-linked, no females are affected. Most affected individuals die before their 20th birthday. Daughters of female carriers of the mutant allele have a 50% chance of also being carriers. Choices: - contagious disease - mutation - infectious disease - a wasting disease A:
a wasting disease

Q: What happens to the density of air as the altitude decreases? Read this paragraph and choose the correct option from the provided answers: The pressure of the earth's atmosphere, as with any fluid, increases with the height of the column of air. In the case of earth's atmosphere, there are some complications. The density of the air is not uniform but decreases with altitude. Additionally there is no distinct top surface from which height can be measured. We can, however, calculate the approximate difference in pressure between two altitudes using the equation . The average pressure of the atmosphere at sea level is 1.013 10 5 Pa. This pressure is often expressed as 101.3 kPa. Choices: - multiplies - remains the same - increases - decreases A:
(Answer)
decreases

Ques: Q: What basic plant structures generally have large surface areas and high surface-to-volume ratios? Read this paragraph and choose the correct option from the provided answers: Choices: - roots - stems - flowers - leaves A:
Ans: leaves

Q: What do you call any force that makes something move in a circle? Read this paragraph and choose the correct option from the provided answers: Centripetal Force is an umbrella term that refers to any force that makes something move in a circle. Examples of forces that can be centripetal forces are as follows: Gravity (the gravity between the Earth and Sun causes the Earth to go in a circle), Friction (the friction force between a car's tires and the road causes the car to turn), Tension (when swinging a bucket around in a circle by holding onto the string, the tension of the string is the centripetal force). Choices: - cyclical - tangential force - momentum - centripetal force A:
(A).
centripetal force

Ques:Q: What does blood pickup from the lungs to be carried throughout the rest of the body? Read this paragraph and choose the correct option from the provided answers: The blood picks up oxygen in the lungs and carries it to cells throughout the body. Choices: - carbon - white blood cells - platelets - oxygen A:

Ans:oxygen

Q: In addition to glucose, what gas is used during cellular respiration? Read this paragraph and choose the correct option from the provided answers: Cellular respiration uses oxygen in addition to glucose. It releases carbon dioxide and water as waste products. Cellular respiration actually "burns" glucose for energy. However, it doesn't produce light or intense heat like burning a candle or log. Instead, it releases the energy slowly, in many small steps. The energy is used to form dozens of molecules of ATP. Choices: - methane - hydrogen - nitrogen - oxygen A:
oxygen
