A hypothesis needs to be validated or rejected, so the first sentence is true because it's his point of view that he wants to investigate. It wouldn't be truth if it's thesis (not hypothesis), because he would have no proof for that.

In maize (corn) plants, a dominant allele I inhibits kernel color, while the recessive allele i permits color when homozygous. A
EleoNora [17]

Answer:

Phenotype ratio= 12 colorless : 3 purple : 1 red

Genotype ratio= 1:2:1:2:4:2:1:2:1

Explanation:

According to the given information, the dominant allele "I" is epistatic to P and p alleles and presence of "I" inhibits the expression of both "P" and "p" alleles.

A cross between two heterozygous plants for both locus would give the F2 progeny in 12 colorless: 3 purple: 1 red ratio.

Here, the F2 genotype with "I-G" and "I-gg" would produce colorless kernels while the ones with "ii-G-" would exhibit purple colored kernels. The F2 genotype "iigg" would beak red kernels.

Hence, the phenotype ratio= 12 colorless : 3 purple : 1 red

Genotype ratio would be same as for the mendelian dihybrid cross= 1 IIPP: 2 IIPp :1 IIpp: 2 IiPP :4 IiPp: 2 Iipp: 1 iiPP :2 iiPp: 1 iipp

What is the most likely pathway taken by a newly synthesized protein that will be secreted by a cell?
monitta

D

Essentially, the path begins from the nucleus where the DNA is transcribed by RNA polymerase that makes a nascent mRNA.

Explanation:

The nascent mRNA is processed into a mature mRNA that is sent to ribosomes that outline the membrane of the Rough Endoplasmic Reticulum. When a polypeptide chain is translated by the ribosome, from the mRNA, the chain enters the lumen of the RER where it finds chaperons that help the proper folding of the chain into a required secondary, tertiary or quaternary structure. The protein undergoes further post-translational modification. Quality Control also happens here and only ‘well-made’ proteins are allowed to pass down to the Golgi apparatus. The Golgi apparatus also performs a few additional post-translation modifications but its major role is tagging these proteins for delivery, and packaging them. Vesicle budding off of this organelle carries the proteins to the cell membrane. The vesicle fuses with the cell membrane enabling the contents in the vesicle to be emptied outside the cell.
