Some processes can't be performed by then, as they are performed in Multicellular organisms like excretion, neural system, hormonal system etc.. otherwise single cell can sustain a life on its own
Correct answer: B. oxygen
<u>Option A</u>) A nucleotide substitution in the coding region of the lactase gene that interferes with the interaction between lactase and lactose.
<h3>
What mutation causes lactase persistance?</h3>
A mutation in a single nucleotide, in which thymine replaces cytosine, in the region that controls the expression of the lactase gene is what causes the lactase persistence trait.
This mutation first occurred in Hungry, and then it spread out to other regions of Europe, Africa, and Asia.
This mutation allowed humans to digest milk during adulthood.
According to this information, we can assume that the correct option is A). A nucleotide substitution in the coding region of the lactase gene that interferes with the interaction between lactase and lactose.

Answer:
One allele of tallness form one of the parent and one allele for dwarfness from another parent.
Explanation:
Mendel took two plants one was homozygous dominant(TT) for height trait and the other was homozygous recessive(tt) for height trait. The homozygous dominant individuals was tall and recessive was short.
So when they are crossed during fertilization the offsprings got one allele for tallness from the homozygous dominant parent and one allele for shortness from the homozygous recessive parent.
T T
t Tt Tt
t Tt Tt
So all the offsprings are heterozygous for the height trait that means all the individuals will be tall in appearance as they have one dominant trait for tallness.
