Explanation:
The SI standard unit of electrical charge is the
coulomb
, represented by the (C) symbol.
One coulomb is the amount of electric charge transported in one second by a steady current of one ampere. One coulomb is also the amount of charge stored by a capacitance of one farad charged to a potential difference of one volt.
Answer: Atmosphere
Explanation:
Atmosphere is the part of the earth, known as the gaseous part, since it contains gases such as nitrogen (about 78%), oxygen (about 21%), Carbondioxide (about 0.03%), and rare gases to make the rest.
Thus, atmosphere contains the most whole of oxygen and carbon dioxide
Answer:
1. the F' plasmid.
2. the bacterial chromosome
3. the bacterial chromosome
4. the F' plasmid.
Explanation:
The F' plasmid is an extrachromosomal DNA molecule composed of genes that act during the transference of genetic material. This plasmid can also be defined as an episome capable of transferring itself into another bacterial chromosome. The bacteria that contain F factor are named F+, while bacteria without this factor are called F-. During conjugation, the F+ factor interacts with F- cells to enable DNA transference among bacteria.
Answer:
Explanation:
They could have conducted the experiment at least thrice for each sample (sand and water) OR done the experiment once but at least in triplicates (i.e obtained six identical 1000 ml beakers; with three beakers for each sample, all ran at once). Also, the same volume of sand put in three of these beakers should be the same volume of water put in the remaining three beakers as rightfully done in the experiment.
The essence of conducting the experiment at least thrice for each sample (sand and water) or done the experiment once but at least in triplicates is to be able to subject there recorded data to statistical analysis; this affords them the opportunity to remove/reduce all forms of error the experiment could have been exposed to during the course of the experiment.
Possible errors include (but not limited to) error due to parallax while taking the volumetric measurements and timing errors.
In the human body the nervous system function is deleting and responding to stimuli.
