Groundwater is enclosed in aquifers. Groundwater
is found within a large range of rocks, but the most effective aquifers
are found in porous, open cavities, and permeable rocks. Aquifers can
contain salty, briny, and fresh water. Groundwater can exit the aquifer
by the pumping of a well, which is usually called discharge. The answer is aquifers.
A balance is best used to measure a sample's mass.
Answer: C
Explanation:
Weighing balance refers to a measuring instrument which is used to measure the mass of the sample.
It has two pans. On one pan, the material to be weighed is placed, with adequate known loads on the other one to such an extent that the shaft will be in balance.
The distinction between the zero perusing and the perusing with the dish stacked demonstrates the contrast between burdens in scale divisions.
Such an instant weighing needs the arms be of equivalent length.
Answer:
They bring dissolved nutrients to the surface of the ocean. They decrease the levels of oxygen at the surface of the ocean. They decrease the amount of nutrients at the surface of the ocean.
Explanation:
Antibiotic used include kenamycin, ampicillin and tetracycline. This is useful to determine if and which bacteria took up the plasmid as they were supposed to during the process of recombination. Host bacteria are normally killed by these antibiotics. If the recombinant plasmids were taken up by the bacteria, plasmid may have contained a DNA gene for resisting the effects of one or more antibiotics. Host bacteria are placed in a growth medium containing an antibiotic to which they have a resistant gene in their recombinant plasmid DNA survivor. If they havent taken the plasmid they die.
