Answer the following question given this paragraph: Fossils may form in other ways. With complete preservation, the organism doesn't change much. As seen below, tree sap may cover an organism and then turn into amber. The original organism is preserved so that scientists might be able to study its DNA. Organisms can also be completely preserved in tar or ice. Molds and casts are another way organisms can be fossilized. A mold is an imprint of an organism left in rock. The organism's remains break down completely. Rock that fills in the mold resembles the original remains. The fossil that forms in the mold is called a cast. Molds and casts usually form in sedimentary rock. With compression, an organism's remains are put under great pressure inside rock layers. This leaves behind a dark stain in the rock. Q: A mold is an imprint of an organism left in what? Choices: - magma - band - fossil - rock A:
rock

Answer the following question given this paragraph: Mutations in regulatory genes that normally control the cell cycle cause cancer. Q: Mutations in regulatory genes that normally control the cell cycle cause what? Choices: - tumors - anxiety - illness - cancer A:
(Answer)
cancer
Ques: Answer the following question given this paragraph: Weight measures the force of gravity pulling downward on an object. The SI unit for weight, like other forces, is the Newton (N). On Earth, a mass of 1 kilogram has a weight of about 10 Newtons because of the pull of Earth's gravity. On the moon, which has less gravity, the same mass would weigh less. Weight is measured with a scale, like the spring scale shown in the Figure below . The scale measures the force with which gravity pulls an object downward. To delve a little deeper into weight and gravity, watch this video:. Q: What is the force that pulls downward on an object and is measured by weight? Choices: - strength - work - light - gravity A:
Ans: gravity
(Q).
Answer the following question given this paragraph: Measurement of exposure to radioactivity is important for anyone who deals with radioactive materials on a regular basis. Perhaps the simplest device is a personal dosimeter, which is a film badge that will fog up when exposed to radiation. The amount of fogging is proportional to the amount of radiation present. Q: What is measured with a personal dosimeter? Choices: - alcohol concentration - blood insulin - internal temperature - exposure to radioactivity A:
(A).
exposure to radioactivity
Ques:Answer the following question given this paragraph: The Chemistry of Carbon What makes organic compounds ubiquitous is the chemistry of their carbon core. Recall that carbon atoms have four electrons in their valence shell, and that the octet rule dictates that atoms tend to react in such a way as to complete their valence shell with eight electrons. Carbon atoms do not complete their valence shells by donating or accepting four electrons. Instead, they readily share electrons via covalent bonds. Q: What makes organic compounds ubiquitous is the chemistry of their what? Choices: - carbon shell - dioxide shell - dioxide core - carbon core A:

Ans:carbon core
Answer the following question given this paragraph: Mating refers to the union of a male and female of the same species for reproduction. The relationship between mates varies by species. Adults may have many mates, or they may mate with just one individual. Mates may stay together only while mating. Or they may stay together for an entire breeding season or even for life. Q: What refers to the union of a male and female of the same species for reproduction? Choices: - asexual reproduction - dating - behavior - mating A:
mating
