Ques:Answer the following question given this paragraph: From the kidneys, urine enters the ureters. These are two muscular tubes that carry urine to the urinary bladder. Contractions of the muscles of the ureters move the urine along by peristalsis. The urinary bladder is a sac-like organ that stores urine. When the bladder is about half full, a sphincter relaxes to let urine flow out of the bladder and into the urethra. The urethra is a muscular tube that carries urine out of the body through another sphincter. The process of urine leaving the body is called urination. The second sphincter and the process of urination are normally under conscious control. Q: What is a sac-like organ that stores urine? Choices: - the colon - the urinary liver - the small intestine - the urinary bladder A:

Ans:the urinary bladder

Ques:Answer the following question given this paragraph: The Process of Science Biology is a science, but what exactly is science? What does the study of biology share with other scientific disciplines? Science (from the Latin scientia, meaning "knowledge") can be defined as knowledge that covers general truths or the operation of general laws, especially when acquired and tested by the scientific method. It becomes clear from this definition that the application of the scientific method plays a major role in science. The scientific method is a method of research with defined steps that include experiments and careful observation. The steps of the scientific method will be examined in detail later, but one of the most important aspects of this method is the testing of hypotheses by means of repeatable experiments. A hypothesis is a suggested explanation for an event, which can be tested. Although using the scientific method is inherent to science, it is inadequate in determining what science is. This is because it is relatively easy to apply the scientific method to disciplines such as physics and chemistry, but when it. Q: What important aspect of the scientific method is a suggested explanation for an event, which can be tested? Choices: - scientific control - string theory - independent variable - hypothesis A:

Ans:hypothesis

Ques:Answer the following question given this paragraph: With fracking, fluids are pumped through a borehole. The fluids create fractures in the rock that contains the natural gas. Chemicals in the fluid prevent the fractures from closing. The natural gas can then be pumped to the surface. Q: In what energy industry process are fluids pumped through a borehole, creating fractures in the rock that contains the natural gas? Choices: - grinding - oil wells - strip mining - fracking A:

Ans:fracking

Q: Pakicetus and rodhocetus are considered to be ancestors of modern what? Choices: - rodents - primates - hominins - whales A:
