Answer the following question given this paragraph: The scientific method is not a step by step, linear process. It is a way of learning about the world through the application of knowledge. Scientists must be able to have an idea of what the answer to an investigation should be. In order for scientists to make educated guesses about the answers, they will base their guesses on previous knowledge, with the notion of extending that knowledge. Scientists will often make an observation and then form a hypothesis to explain why a phenomenon occurred. They use all of their knowledge and a bit of imagination in their journey of discovery. Q: In the scientific method, what is the initial, unproven explanation for why something is occurring? Choices: - concepts - idea - theories - hypothesis A:
(Answer)
hypothesis
Ques: Answer the following question given this paragraph: 8.3 The Pelvic Girdle and Pelvis The pelvic girdle, consisting of a hip bone, serves to attach a lower limb to the axial skeleton. The hip bone articulates posteriorly at the sacroiliac joint with the sacrum, which is part of the axial skeleton. The right and left hip bones converge anteriorly and articulate with each other at the pubic symphysis. The combination of the hip bone, the sacrum, and the coccyx forms the pelvis. The pelvis has a pronounced anterior tilt. The primary function of the pelvis is to support the upper body and transfer body weight to the lower limbs. It also serves as the site of attachment for multiple muscles. The hip bone consists of three regions: the ilium, ischium, and pubis. The ilium forms the large, fan-like region of the hip bone. The superior margin of this area is the iliac crest. Located at either end of the iliac crest are the anterior superior and posterior superior iliac spines. Inferior to these are the anterior inferior and posterior inferior iliac spines. The auricular surface of the ilium articulates with the sacrum to form the sacroiliac joint. The medial surface of the upper ilium forms the iliac fossa, with the arcuate line marking the inferior limit of this area. The posterior margin of the ilium has the large greater sciatic notch. Q: The pelvic girdle, consisting of a hip bone, serves to attach a lower limb to this? Choices: - exoskeleton - appendicular skeleton - cytoskeleton - axial skeleton A:
Ans: axial skeleton
(Q).
Answer the following question given this paragraph: At some time in the past, a variation probably came from a mutation. A mutation is a random change in an organism's genes ( Figure below ). Mutations are natural. Some are harmful, but many are neutral. If a mutation is harmful, the organism may not live to reproduce. If the mutation is beneficial, that organism may have a better chance to survive. An organism that survives is likely to have offspring. If it does, it may pass the mutation on to its offspring. The offspring may be more likely to survive. Q: What is a random change in an organism's genes? Choices: - meiosis - infection - accumulation - mutation A:
(A).
mutation
Ques:Answer the following question given this paragraph: Figure 14.7 (a) Energy is required to partially overcome the attractive forces between molecules in a solid to form a liquid. That same energy must be removed for freezing to take place. (b) Molecules are separated by large distances when going from liquid to vapor, requiring significant energy to overcome molecular attraction. The same energy must be removed for condensation to take place. There is no temperature change until a phase change is complete. Q: What is required to partially overcome the attractive forces between molecules in a solid to form a liquid? Choices: - fuel - hydrogen - oxygen - energy A:

Ans:energy
Ques:Answer the following question given this paragraph: Enzymes are proteins that speed up biochemical reactions in cells. Antibodies are proteins that target pathogens for destruction.

Ans:
enzymes
