The scientific investigation is the systematic approach of the scientists to answer the questions about the world. It is applied almost all of the theories including the Theory of Natural Selection.

Thermal denaturation experiments can be used to follow the transition of double-stranded DNA into single-stranded DNA. Which par
tia_tia [17]

Answer:

I, II and III

Explanation:

The melting temperature of a DNA double helix is affected by several factors that affect the hydrogen bonds and /or the other interactions involved in maintaining the helical structure. Two DNA strands of a helix are held together by the hydrogen bonds between the complementary nitrogenous bases. The pH of the solution would affect the hydrogen bonds. If the pH is too acidic, the hydrogen bonds acceptor atoms will accept protons from the solution and would not be able to make hydrogen bonds.  

The ionic strength of the solution represents the ions present in it. If the solution has positively charged ions, the negative charges of phosphate residues of the DNA backbone will be neutralized. This would make the double helix more stable. Similarly, a longer DNA strand would have a higher melting temperature as more heat will be required to break more hydrogen bonds as compared to a shorter DNA strand.

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers;
kipiarov [429]

Answer:

Answer is 3/16.

Explanation:

If the F1 progeny has red axial flowers this shows us that red and axial genes are dominant. If we say that R is for red dominant gene, r is for white recessive gene.

If we say A is axial dominant gene, a is for terminal recessive gene.

All F1 progeny has AaRr phenotype.

When we cross them, Aa x Aa  can have AA Aa Aa aa

When Rr x Rr crossed, RR Rr Rr rr

The F2 progeny can have white axial flowers by having a and R in the phenotype with the possibility having aa= 1/4 , R in the phenotype , the possibility is 3/4.

1/4 x 3/4 = 3/16 in all F2 progeny
