Answer the following question given this paragraph: The evolution of life on Earth over the past 4 billion years has resulted in a huge variety of species. For more than 2,000 years, humans have been trying to classify the great diversity of life. The science of classifying organisms is called taxonomy. Classification is an important step in understanding the present diversity and past evolutionary history of life on Earth. Q: What is the science of classifying the many organisms on earth called? Choices: - general classification - terminology - methodology - taxonomy A:
taxonomy

Choices: - available safety symbols - medical safety symbols - first aid safety symbols - lab safety symbols A:
(Answer)
lab safety symbols
Ques: Answer the following question given this paragraph: The ideal gas law is used like any other gas law, with attention paid to the unit and making sure that temperature is expressed in Kelvin. However, the ideal gas law does not require a change in the conditions of a gas sample. The ideal gas law implies that if you know any three of the physical properties of a gas, you can calculate the fourth property. Q: The ideal gas law is used like any other gas law, with attention paid to the unit and making sure that temperature is expressed in kelvin. however, the ideal gas law does not require a change in the conditions of a gas sample. the ideal gas law implies that if you know any three of the physical properties of a gas, you can calculate this? Choices: - second - third - unrelated - fourth A:
Ans: fourth
(Q).
Answer the following question given this paragraph: Wave amplitude is determined by the energy of the disturbance that causes the wave. A wave caused by a disturbance with more energy has greater amplitude. Q: What is determined by the energy of the disturbance that causes the wave? Choices: - wavelength - Ohm - frequency - wave amplitude A:
(A).
wave amplitude
Ques:Answer the following question given this paragraph: A trophic level is a feeding position in a food chain or food web. Most food chains and webs have a maximum of four trophic levels. There is less energy and biomass at higher trophic levels. Q: Most food chains and webs have a maximum of how many trophic levels? Choices: - 3 - 10 - 6 - 4 A:

Ans:4
Answer the following question given this paragraph: Buffer Systems in the Body The buffer systems in the human body are extremely efficient, and different systems work at different rates. It takes only seconds for the chemical buffers in the blood to make adjustments to pH. The respiratory tract can adjust the blood pH upward in minutes by exhaling CO2 from the body. The renal system can also adjust blood pH through the excretion of hydrogen ions (H+) and the conservation of bicarbonate, but this process takes hours to days to have an effect. The buffer systems functioning in blood plasma include plasma proteins, phosphate, and bicarbonate and carbonic acid buffers. The kidneys help control acid-base balance by excreting hydrogen ions and generating bicarbonate that helps maintain blood plasma pH within a normal range. Protein buffer systems work predominantly inside cells. Q: The kidneys help control acid-base balance by excreting _____ and generating bicarbonate that helps maintain blood plasma ph within a normal range? Choices: - magnesium ions - sodium ions - lithium ions - hydrogen ions A:
hydrogen ions
