Answer:
of course ethe answer should be option c
The probability of progenies to have red flower is 50%.
<h3><u>Explanation:</u></h3>
The phenomenon where the two pure alleles of a particular character present in an individual gives a mixed appearance is called incomplete dominance, where the dominant character cannot fully mask the presence of a recessive character.
Here In the cross between a red flowering plant and the pink flowering plant, the character shows the incomplete dominance.
Let the allele for dominant character i.e red flower be R and recessive character white be r.
So the genotype for red flowering plant = RR.
The genotype for pink flowering plant =Rr.
The gametes from red flowering plant =R.
The gametes from pink flowering plant =R and r.
So with the cross, the genotype of the offsprings will be 50% RR and 50% Rr.
So plants with red flowers will be 50% of the whole progeny.

According to this phyletic lineage, Cambrian (542 to 488 million years ago) and Silurian (443 to 416) are younger than Triassic (251 to 199), whereas Jurassic (199.6 to 145.5), Cretaceous (145 to 65), and Neogene ( 23 to 2.6) came later.
Answer:
A
Explanation:
Radioactive dating uses carbon isotopes to determine the age of a material.
Answer:
c. Brownian ratchet
Explanation:
Mitochondria are cell organelles. They are known as the power house of the cells. The energy needed to power the cell is generated by the mitochondria. They functions like a digestive system.
The mitochondria chaperone are proteins that helps the proteins along pathways for their folding. They shield the proteins from other proteins and protect them from binding the folding process. The chaperone are mainly concern with the folding of protein.
The chaperone acts as a Brownian ratchet as the mitochondrial chaperone guides the matrix protein into matrix by the biased diffusion process.
