Answer the following question given this paragraph: Water on Earth is billions of years old. However, individual water molecules keep moving through the water cycle. The water cycle is a global cycle. It takes place on, above, and below Earth's surface, as shown in Figure below . Q: What global cycle takes place on, above, and below earth's surface? Choices: - aqua cycle - water flow - water wheel - water cycle A:
water cycle
(Question)
Answer the following question given this paragraph: After food is broken down into nutrient molecules, the molecules are absorbed by the blood. Absorption is the process in which nutrients or other molecules are taken up by the blood. Once absorbed by the blood, nutrients can travel in the bloodstream to cells throughout the body. Q: What type of fertilization do most reptiles use to reproduce? Choices: - mechanical - external - asexual - internal A:
(Answer)
internal
Ques: Answer the following question given this paragraph: Darwin proposed the theory of evolution by natural selection. Evolution is a change in the inherited traits of organisms over time. Natural selection is the process by which living things with beneficial traits produce more offspring, so their traits become more common over time. Q: What is the term for a change in the inherited traits of organisms over time? Choices: - mutation - emergence - generation - evolution A:
Ans: evolution
(Q).
Answer the following question given this paragraph: Less often, a new species arises without geographic separation. This is called sympatric speciation . The following example shows one way this can occur. Q: What is it called when a new species arises without geographic separation? Choices: - spontaneous evolution - Allopatric speciation - quantum speciation - sympatric speciation A:
(A).
sympatric speciation
Ques:Answer the following question given this paragraph: The exothermic reaction on the left releases energy. The endothermic reaction on the right consumes energy. Q: What do you call a reaction that consumes energy as it is carried out? Choices: - autotrophic - exothermic - unstable - endothermic A:

Ans:endothermic
Ques: Answer the following question given this paragraph: Development of Bone Ossification, or osteogenesis, is the process of bone formation by osteoblasts. Ossification is distinct from the process of calcification; whereas calcification takes place during the ossification of bones, it can also occur in other tissues. Ossification begins approximately six weeks after fertilization in an embryo. Before this time, the embryonic skeleton consists entirely of fibrous membranes and hyaline cartilage. The development of bone from fibrous membranes is called intramembranous ossification; development from hyaline cartilage is called endochondral ossification. Bone growth continues until approximately age 25. Bones can grow in thickness throughout life, but after age 25, ossification functions primarily in bone remodeling and repair. Q: What begins approximately six weeks after fertilization in an embryo? Choices: - calcification - elongation - incubation - ossification A:
Ans:
ossification
