Answer:
1:1:1:1 walnut comb
Explanation:
If a cross is made between a female who is RRpp (rose comb) and a male who is rrPP (pea comb) then:
P: RRpp x rrPP
F1: RrPp RrPp RrPp RrPp
This means that all of the offspring in F1 generation will have heterozygous genotype (at both loci). Since it contains both dominant alleles, the phenotype is walnut comb.
Water is more of a radical it brings moisture and it has great power in its surf clouds are made from the moisture water is like a power sorce for storms and other things
Chemical (mutagens)
usually either mimic the structure of nucleotides and are inserted in DNA or either cause
chemical changes (such as alkylation) in nucleotides hence causing mismatching during replication.
Radiation, on the other hand, (due to its high energy) causes double-strand breaks in DNA causing an
increased likelihood of mutations during the repair of the DNA by cell
mechanisms.
Answer:
The acidic environment in the stomach stops the action of the amylase enzyme.
The stomach will secrete digestive juice that contain hydrochloric acid and digestive enzyme such as pepsin to digest protein.
The HCL create an acidic environment that will deform the ionic and hydrogen bond of the amylase which cause the enzyme to be denatured.
