Answer:
b) dumping used oil into street drains
Explanation:
Answer:
Performing the ischemia/reperfusion experiment using neutrophil-depleted animals and examining whether the degree of tissue damage is reduced
Explanation:
Neutrophils are one of the important component of the white blood cells. Neutrophils has the ability to phagocytose the cell and these cells first reach at the time of parasitic infections.
In case of reperfusion experiment, the neutrophil cells can be used to obtain the best results. The variables that are used in the experiment can be tested and is limited in the absence and the presence of the neutrophil cells. The tissue damage can be diagnosed by this experiment.
Thus, the correct answer is option (B).
Let be E the epicenter, a and b are the stations
E a b
----/---------------------/-------------------------/------------
just after the earthquake has occured, waves must detected step by step, from a, then after from b, Ea < Eb, so , <span>b is farther from the epicenter than
a.</span>
DNA -- RNA -- TRNA--- amino acid--- protein
DNA (DeoxyRiboNucleicacid) creates RNA (RiboNucleicAcid) which is DNA basically cut in half vertical this then is "translated into a code of amino acids" by TransferRNA then these codons (3 bases grabbed by transferRNA) are turned to amino acids from there after the sequence is done you have a protien full of information on what to do
Answer:
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content. Quartzite generally comprises greater than 90% percent quartz, and some examples, containing up to 99% quartz, and are the largest and purest concentrations of silica in the Earth's crust. Although a quartz-rich sandstone can look similar to quartzite, a fresh broken surface of quartzite will show breakage across quartz grains, whereas the sandstone will break around quartz grains. Quartzite also tends to have a sugary appearance and glassy lustre. The variety of colours displayed by quartzite are a consequence of minor amounts of impurities being incorporated with the quartz during metamorphism. Although quartzite can sometimes appear superficially similar to marble, a piece of quartzite will not be able to be scratched by a metal blade, and quartzite will not fizz on contact with dilute hydrochloric acid.Explanation:
