Answer the following question given this paragraph: When bacteria are destroyed by leukocytes, pyrogens are released into the blood. Pyrogens reset the body's thermostat to a higher temperature, resulting in fever. How might pyrogens cause the body temperature to rise?. Q: When bacteria are destroyed by leukocytes, what are released into the blood? Choices: - carcinogens - proteins - sporozoans - pyrogens A:
pyrogens

Answer the following question given this paragraph: The two ribosomal subunits are named base on their sedmentation rate in a centrifuge. The unit of measurement is the Svedberg unit , a measure of the rate of sedimentation, not the size. This accounts for why fragment names do not add up (70S is made of 50S and 30S). Q: The svedberg unit is a measure of the rate of what, which is tested in a centrifuge? Choices: - precipitation - temperature - secretion - sedimentation A:
(Answer)
sedimentation
Ques: Answer the following question given this paragraph: Alkaliphiles are organisms that "love" bases. Bases are like the opposite of acids. Basic environments where archaeans are found include Mono Lake in California, pictured in Figure below . Mono Lake is the oldest lake in North America. The water is not only unusually basic. It's also saltier than the ocean. So archaeans that live in the water of Mono Lake must have adaptations to both salty and basic conditions. They are haloalkaliphiles. Q: What is the term for organisms that have adaptations to both salty and basic conditions? Choices: - salinophytes - sporozoans - heterophiles - haloalkaliphiles A:
Ans: haloalkaliphiles

Answer the following question given this paragraph: Two interesting properties of liquids are surface tension and viscosity. Q: Surface tension and viscosity are generally associated with what form or state of matter? Choices: - solids - gases - electrons - liquids A:
(A).
liquids
Ques:Answer the following question given this paragraph: The first and longest phase of mitosis is prophase . During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles of the cell. As the centrioles move, a spindle starts to form between them. The spindle, shown in Figure below , consists of fibers made of microtubules. Q: Chromatin condenses into chromosomes during prophase, the first and longest phase of what process? Choices: - reproduction - apoptosis - meiosis - mitosis A:

Ans:mitosis
Answer the following question given this paragraph: The molecular mass is the sum of the masses of the atoms in the formula. Q: The sum of the masses of the atoms in the formula is referred to as what? Choices: - nucleus mass - magnetic mass - atomic mass - molecular mass A:
molecular mass
