the thylakoid will have fewer hydrogen ions
The invention of PCR make DNA fingerprinting possible because "PCR made it possible to produce enough copies for reliable tests".
<u>Option: C</u>
<u>Explanation:</u>
With the development of the PCR technique, DNA profiling has made enormous progress both in its distinguishing capacity and in its ability to survive information from very limited or damaged beginning samples. The PCR cycle mimics the biochemical mechanism of DNA replication yet restricts it to fragments of concern unique to DNA.
In the PCR method, the specimen of DNA is denatured by heating into separate polynucleotide strands. Two primers of DNA oligonucleotides are used for hybridization on opposite DNA strands to two matching nearby sites. Thus two new copies of the interest sequences are produced. Quantitative PCR methods allow accurate, high and automated calculations of the throughput.
The function of the excretory system is to remove wastes (excrete wastes).
Answer:
the nucleus, ribosomes, the rough endoplasmic reticulum and the Golgi apparatus
Explanation:
The statement about pesticides and herbicides that is not true is B) Once the pesticides and herbicides break down, they are no longer harmful. In fact, they remain harmful long after they break down, so this option is incorrect.
