Answer:
The correct answer is option D) six dominant and two recessive.
Explanation:
The most common genetic inheritance pattern involves cross between heterozygous recessive parents which means it has one allele of each character in every parent (suppose Tt).
Cross between these parents provide these offspring; TT, Tt, Tt, and tt which exhibit 3:1 ration which can also be mention as 6:2 which means 6 out of the 8 has dominant (homozygous or heterozygous) and 2 out of 8 offsprings are recessive alleles.
Thus, the correct answer is option D) six dominant and two recessive.
Answer:
Ribose
Explanation:
DNA is a large molecule, a type of nucleic acid which store and act as a genetic material of the cell. DNA molecule is formed by the repeating monomer units called nucleotides.
Each nucleotide is made up of three subunits as:
1. 5-C sugar: De-oxyribose formed by the removal of oxygen group from 2' OH group of ribose. Ribose is the sugar molecule present in RNA nucleic acid.
2. Phosphate group (PO₄³⁻)
3. Nitrogenous bases: adenine, guanine, adenine and cytosine.
Thus, ribose is the correct answer.
a dialyzing membrane: is a membrane that retains macromolecules (like proteins, lipids) but passes some solute (small molecules) such as ions, glucose, and urea.
This phenomenon is used in medicine (specifically nephrology) in hemodialysis: The dialyzing membrane An exchange module between the internal medium (blood) and the external environment (hemodialyzer), and an electrolytic solution for exchange. The dialysis session is provided by a dialysis machine. It saved patient with chronic renal failure who cannot do renal transplantation by eliminating substances that his body cannot do anymore, like the excess of the urea and ions like sodium, potassium, and chloride.
