Answer:
25% heterozygous tall
Explanation:
If we take the F1 generation as parents and let them self-fertilise, we have 4 crosses.
The first one for homozygous tall, then we have 100% AA.
The second and third one for heterozygous tall and we have 25% AA, 50%Aa and 25%aa for each of them.
The last one would be for dwarf, and we'll have 100%aa.
Adding all of them, we'll have
AA = 100 + 25 + 25 = 150%
Aa = 50+50 = 100%
aa = 100 + 25 + 25 = 150%
as we had 4 crosses, so dividing the total percentages by 4, we'll have,
AA = 37.5%
Aa = 25%
aa = 37.5%
:. The percentage of heterozygous tall would be 25%.

Answer: Lungs
Explanation:
Examples of endocrine organs include the pancreas, which produces the hormones insulin and glucagon to regulate blood-glucose levels, the adrenal glands, which produce hormones such as epinephrine and norepinephrine that regulate responses to stress, and the thyroid gland, which produces thyroid hormones that regulate to the Lungs.
Answer:
A. All lipids are insoluble in water.
Explanation:
Macro molecules are also called polymers, which are formed as a result of polymerization of molecules such as carbon, hydrogen and oxygen.
There are four types of macro molecules in the mammalian system which are
- lipids
- nucleic acid
- protein
- carbohydrates
Lipids are macro molecules that do not dissolve in water i.e. they are hydrophobic. they help in the formation of cell membranes and hormones in the body.
Answer:
It connects the brain to the rest of the body.
Answer:
The correct answer is - DNA --> RNA --> amino acid --> protein --> phenotype.
Explanation:
DNA encodes for the RNA and RNA encodes for the proteins in the process of central dogma to produce protein in two processes called transcription and translation to produce protein.
It begins with encoding DNA into RNA (mRNA), known as transcription, which is moved to the ribosome to translate into amino acid chains with help of tRNA and makes a specific protein which could be a form of genotype which express itself to produce a specific trait that makes a particular phenotype of that trait.
