Answer the following question given this paragraph: One common example of an extra-chromosome disorder is Down syndrome ( Figure below ). Children with Down syndrome are mentally disabled and also have physical deformities. Down syndrome occurs when a baby receives an extra chromosome 21 from one of his or her parents. Usually, a child will receive one chromosome 21 from the mother and one chromosome 21 from the father. In an individual with Down syndrome, however, there are three copies of chromosome 21 ( Figure below ). Therefore, Down syndrome is also known as Trisomy 21. These people have 47 total chromosomes. Q: What's the most common disorder from having an extra chromosome? Choices: - Williams syndrome - Turner syndrome - cri-du-chat syndrome - down syndrome A:
(Answer)
down syndrome
Ques: Answer the following question given this paragraph: Renewable resources are natural resources that can be replaced in a relatively short period of time or are virtually limitless in supply. Renewable energy resources include sunlight, moving water, wind, biomass, and geothermal energy. Each of these energy resources is described in Table below . Resources such as sunlight and wind are limitless in supply, so they will never run out. Besides their availability, renewable energy resources also have the advantage of producing little if any pollution and not contributing to global warming. The technology needed to gather energy from renewable resources is currently expensive to install, but most of the resources themselves are free for the taking. Q: What are natural resources which can be replaced in a relatively short period called? Choices: - solvent resources - materials resources - replaceable resources - renewable resources A:
Ans: renewable resources
(Q).
Answer the following question given this paragraph: The mouth is the first organ that food enters. But digestion may start even before you put the first bite of food into your mouth. Just seeing or smelling food can cause the release of saliva and digestive enzymes in your mouth. Q: What is the first digestive organ that food enters? Choices: - intestine - digestive system - kidneys - mouth A:
(A).
mouth

Q: What branch of science deals with the effects people have on the environment? Choices: - physical science - cultural science - ecological science - environmental science A:

Ans:environmental science
Answer the following question given this paragraph: Although air can transfer heat rapidly by convection, it is a poor conductor and thus a good insulator. The amount of available space for airflow determines whether air acts as an insulator or conductor. The space between the inside and outside walls of a house, for example, is about 9 cm (3.5 in) large enough for convection to work effectively. The addition of wall insulation prevents airflow, so heat loss (or gain) is decreased. Similarly, the gap between the two panes of a double-paned window is about 1 cm, which prevents convection and takes advantage of air's low conductivity to prevent greater loss. Fur, fiber, and fiberglass also take advantage of the low conductivity of air by trapping it in spaces too small to support convection, as shown in the figure. Fur and feathers are lightweight and thus ideal for the protection of animals. Q: Although air can transfer heat rapidly by convection, it is a poor conductor and thus a good what? Choices: - magnet - absorber - transporter - insulator A:
insulator
