Pretty sure temperature, Celsius and Fahrenheit are both ways to measure the temperature weather it is hot or cold
I believe that oxygen and silicon are the most common elements found in the Earth's crust.
Answer:
Nitrogen fixation is a process whereby bacteria in the soil convert atmospheric nitrogen ( N2 gas) into a form that plants can use. ... Animals get their nitrogen by eating plants or other animals. Finally, all organisms need a steady supply of nitrogen because it is a building block of DNA and RNA, and of proteins.
Hope this helps! :)
In the heterozygous state (w +/w), a variegated eye is produced, with white and red patches. The following statements are true in relation to this experiment:
b. When heterochromatin spreading does not reach the new location of the w + allele, the gene will be transcribed, producing red eye patches.
c. When heterochromatin spreading encompasses the new location of w + allele, the gene is transcribed, producing white eye patches.
d. Even though eye color phenotypic variegation exists within the eye, all cells have the same genotype.
Explanation:
Heterochromatin in droshophila has genes which gets expressed by position effect variegation. In some normally active cells genes are silenced in some due to transposition of genes which causes change or variegating in phenotype.
This change is due to change in position of the gene in the genome and chromosome but no change in gene.
The variegation in drsophilla melanogaster shows that white gene was not damaged.
The rearrrangement of gene takees place at pericentric heterochromatin.
Heterochromatin is required for maintaining genome integrity and regulating gene expression. When spread in neighboring region it can inactivate the genes present there.
The genes taking part in variegation remains same hence no change in genotype.
Answer:
A
Explanation:
First, you need to isolate the DNA from the subjects sample. Second, you need to amplify that DNA with PCR in order to be able to see enough DNA during gel electrophoresis at the end. Third, restriction enzymes are used in order to cut the DNA at specific sites. Fourth, you separate these small fragments using gel electrophoresis. The gel will give you a visual indication of all the fragments present in the subjects sample and thus help you profile the subjects DNA.
