Answer:
See the answer below
Explanation:
1. <u>Only one phenotype</u> is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.
2. <u>Two phenotypes </u>are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.
3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:
AA x aa
Aa Aa Aa Aa
All the F1 offspring will appear tall and their genotypes would be heterozygous.
4. Assuming that the allele for height is denoted with A (a), <u>the genotype of the purebred tall plant would be AA. </u>
5. In a similia vein, <u>the genotype of the purebred short plant would be aa. </u>
Once food is in the small intestine, it stimulates the pancreas to release fluid containing a high concentration of bicarbonate. This fluid neutralizes the highly acidic gastric juice, which would otherwise damage the membrane lining of the intestine, resulting in a duodenal ulcer.

I believe that it is because when you put the hand on ice it causes the hand too cool and prevents/slows the rate at which the nerves get damaged.
The answer is; C
Plasmids are conferred through horizontal gene transfer in bacteria. The ‘male’ bacteria develops a structure called pili that then attaches to the ‘female’ bacteria. It then transfers it’s replicated plasmid to the ‘female’ bacteria in a process called conjugation. This bacteria will hence have desirable traits that are coded for by the transferred genetic material ,such as antibiotic resistance, after a process called recombination.
Answer: double helix
Explanation: The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.
