The question has options that are given as below:
A. Some potatoes would be more likely to have a genetic resistance to the disease and survive. B. The potatoes would have been able to trade genes so that they could survive the disease. C. More of the potatoes would have been edible varieties. D. None of the potatoes would have been infected by the disease.
Answer:
The correct answer is - A. Some potatoes would be more likely to have a genetic resistance to the disease and survive.
Explanation:
Genetic resistance is the capability or ability of some individual organisms of a population or species have to adapt the environmental or genetic changes and survive while other organisms of species are not able to do the same.
In this case, some of the potatoes more likely to show genetic resistance to the disease and condition and survive from the devastation of the potato blight
Answer:
1707-1778- Carolus LinnaeusHedeveloped the two part naming system fororganisms, using the genus and species,known as scientific naming.1707-1788- Georges-Louis Leclerc,Comte de BuffonIn his writings, he notedthat different regions of the world havedistinct plants and animals, even when theyhave similar environments. This isconsidered to be the first principle ofbiogeography. Buffon also suggested thatspecies may have improved and degeneratedsince creation, and that the Earth is probablymuch older than the 6,000 years widelyaccepted at the time.1769-1832- Georges Cuvier- influencedby the writings of Buffon, Cuvier foundthat layers, or strata, in the Earth's rockeach represent a different period in theEarth's history.

Answer:
complementary base-pairing rules
Explanation:
DNA is the genetic material of living cells. It is a long chain of double-stranded molecules, in which each strand is complementary to one another i.e. Adenine base is paired with Thymine base while Guanine base pairs with Cytosine base following the complementary base pairing rule as proposed by Chargaff. This pairing is responsible for the double helical structure of the DNA.
The complementary base pairs that a DNA molecule contains make it able to produce identical copies of itself during replication or duplication. Before replication of DNA can occur, the double strands need to unwind to form two separate strands, which serves as a template for the synthesis of new complementary strands.
In this manner, each new strand contains one template strand and one complementary strand, which forms two new double helix that is identical to the original strand. This two identical copies of DNA gets separated into two daughter cells, which is the essence of the DNA replication.
Answer:
At least 17 PCR cycles or 16 PCR cycles
Explanation:
As we know -
In one chain of heating and cooling of polymerase chain reaction (PCR), the strands of DNA gets doubled.
The general mathematical representation of this is
where "n" is the number of PCR cycles.
It is given that DNA strands to be produced is 16 times the original quantity of DNA.
So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less than 16 times the original quantity of DNA
