There were many reasons. For starters, the entire economy was based around slaves working on plantations of things like tobacco or for making gin. Without them the state would break down because they wouldn't have the free workforce that they had when they had slaves. Also, it would also help the northern states and abolitionists since there would be more non slave than slave states.
Answer:
Townshed act/Townshed Duties
Explanation:
The term "genomic library" refers to a collection of brief DNA fragments that will be submitted to massively parallel sequencing to yield sequence reads, also known as "next generation sequencing," which are DNA sequences or base pairs of those DNA fragments.
A genomic library includes every sequence found in an organism's genome (apart from any sequences, such as telomeres that cannot be readily cloned). It is a group of cloned, restriction-enzyme-digested DNA fragments that include copies of all the DNA sequences found in a genome. An organism's full genome is represented as a collection of DNA fragments put into a vector molecule.
A genomic library could be created using a plasmid vector in the case of organisms with tiny genomic sizes, such E. coli. Only 5000 clones in this scenario (with an average DNA insert size of 5 kb) would provide a higher than 99% chance of successfully replicating the whole genome (4.6 x106 bp).
Lambda phage, BAC, or YAC vectors are used to build the majority of libraries from organisms with bigger genomic library. These can accept DNA inserts that are about 23,45,350 and 1000 kb in size, respectively. Because of this, fewer recombinants are required than with plasmids to span the entire genome.

Farm. The intersection of these two rivers created what was known as the Fertile Crescent. And allowed for the beginning of farming and agriculture
Answer:
RrYy x RrYy
Explanation:
Given
Round (R) allele is dominant over wrinkled allele "r"
and Yellow seed allele (Y) is dominant over green seed allele "y"
If I find a plant with round and yellow seeds and want to determine its genotype, then I will cross it with plant that has heterozygous genotype for both the characteristics i.e "RrYy"
Let us say that the plant I found is heterozygous dominant for both the traits i.e "RrYy"
If RrYy is crossed with another RrYy ,we get -
RY Ry rY ry
RY RRYY RRYy RrYY RrYy
Ry RRYy RRyy RrYy Rryy
rY RrYY RrYy rrYY rrYy
ry RrYy Rryy rrYy rryy
Thus, the possible gnotypes would be
RRYY-1
RRYy-2
RrYY-2
RrYy-4
RRyy- 1
Rryy-2
rrYY-1
rrYy-2
rryy-1
The phenotypic ration for this cross is
. This is a standard cross result between two heterozygous parents.
