Answer:
(C) Conventional wastewater purification systems have not been fully successful in killing bacteria at cold temperatures
Explanation:
According to the statement, the QuickFreeze’s purification system is a complement to conventional wastewater treatment systems, because it is a system that only kills bacteria at low temperatures. Therefore, <u>municipalities will have to keep their traditional systems for when temperatures aren’t so low</u>.
Let’s consider the different arguments to try to convince the municipality to buy the system:
A) It is an argument that detracts from the need to acquire QF technology since this technology does not control other impurities.
B) It doesn’t help to justify the acquisition of the QF system since this technology it’s not a replacement but a complement.
C) If there are limitations in conventional methods, especially at low temperatures, using the QF system would seem to be an excellent option to kill all bacteria.
D) It is not a strong enough reason to buy it.
E) It is an irrelevant statement.
Plant cells have cell walls and vacuoles.
The cell wall and the vacuole is what keeps the plant standing up.
The cell wall is a rigid layer outside of the cell.
The vacuole is a space within the cell that contains water. When the plant has a lot of water, it will be rigid and stand up right. If you do not water your plant well, the plant may lose its rigidity.
The answer is chromosome ....
Answer: A-T or G-C
Explanation:
The single-nucleotide polymorphism in human genomes is a substitution of a single nucleotide which occur in a specific position at the genome. The A-T nucleotide may appear dominant in the most population, while the remaining minor population may have the G-C nucleotide. The DNA molecule in the population at this site have A-T or G-C.
