Ques: 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:
Ans: a wasting disease

Ans: dormancy

Ques: Q: Concentric circles that spread out through the water around the droplets are actually types of what moving through the water? Read this paragraph and choose the correct option from the provided answers: No doubt you've seen this happen. Droplets of water fall into a body of water, and concentric circles spread out through the water around the droplets. The concentric circles are waves moving through the water. Choices: - winds - troughs - lines - waves A:
Ans: waves

Ques: Q: The conservation of momentum principle can be applied to systems as different as a comet striking earth and a gas containing huge numbers of atoms and these? Read this paragraph and choose the correct option from the provided answers: The conservation of momentum principle can be applied to systems as different as a comet striking Earth and a gas containing huge numbers of atoms and molecules. Conservation of momentum is violated only when the net external force is not zero. But another larger system can always be considered in which momentum is conserved by simply including the source of the external force. For example, in the collision of two cars considered above, the two-car system conserves momentum while each one-car system does not.
