Answer:
I got this off of g o o g l e
Explanation:
I put pairs of small fence posts (one on each side) down the row. I then tied twine to the fence post and ran it on either side of the plants. This keeps them from falling over to the side. If you plant thick enough they won't fall to the front or back.
Answer:
How cloning works: In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed. ... This young animal is referred to as a clone.
Basics of cloning:
Isolation of target DNA fragments (often referred to as inserts)
Ligation of inserts into an appropriate cloning vector, creating recombinant molecules (e.g., plasmids)
Transformation of recombinant plasmids into bacteria or other suitable host for propagation.
Screening/selection of hosts containing the intended recombinant plasmid .
Explanation:
The correct answer is A. Lac repressor.
Lac repressor prevents lac gene which are found in the DNA of Escherichia Coli from being expressed for many times.
Lac repressor is termed as DNA which binds proteins. It allows the expression of genes from coding which are made for proteins to be involved in metabolism of lactose which is in bacteria.
When there is no lactose which is available in the cell, then the genes are being repressed. Lactose are being converted to allolactose if they are available.
The four factors are availability of food, water, shelter and space. The effect they have on the population includes: lower birth rates, increasing death rates or leading to emigration
Answer:
F1= All Yy
F1= All yellow
F2= 1/4 YY: 1/2 Yy: 1/4 yy
F2= 3/4 yellow: 1/4 green
Explanation:
The allele for the yellow-colored seeds (Y) is dominant over the allele that imparts green phenotype (y). A cross between two pure breeding yellow seeded and green seeded plants would obtain all yellow seeded plants in the F1 generation. Self-pollination of F1 progeny would obtain F2 generation in following phenotype and genotype ratio:
Phenotype ratio= 3/4 yellow: 1/4 green
Genotype ratio= 1/4 YY: 1/2 Yy: 1/4 yy
