Phenotypes are the physical characteristics that result from the genotype, which is the genetic makeup of the organism. In this case, either straight hairline or Widow's peak will be the phenotype, as they are the physical characteristics being discussed.
The questions states that a Widow's peak is dominant over straight hairline. So we are going to assume that the Widow's peak allele is W (dominant), and the straight hairline allele is w (recessive).
A dominant allele will mask the presence of a recessive allele unless both of the alleles are both recessive (both ww).
So for the WW genotype, we are going to see the dominant phenotype: Widow's peak.
For the Ww genotype, we are also going to see the dominant phenotype since the dominant allele is going to mask the presence of the recessive allele, so we are going to see: Widow's peak.
Lastly, for the ww genotype, we are going to now see the recessive phenotype, since both alleles are recessive: straight hairline. Note that their are two of these type of offspring as stated in the question.
i looked it up and got this and im too lazy to write it so look at the picture
First of all just to point out that this isn't a biology question :)
Ok so to solve this you have to expand to spare first
8k(4k^2-12k+9)
Then multiply the 8k
32k^3-96k^2+72k is the answer
Answer: the amount of air that normally enters the lungs during quiet breathing, which is about 500 milliliters.
Explanation:
C
Explanation:
The only hydrocarbon from the given options is molecule C.
The compound is an aromatic hydrocarbon.
- Hydrocarbons are compound composed of hydrogen and carbon only .
- A hydrocarbon is mostly made up of two atoms that are covalently bonded to one another.
- The major source of hydrocarbons is crude oil or petroleum, natural gas and coal.
- There are many known hydrocarbons.
- Most hydrocarbons burn in excess air to produce carbon dioxide and water.
- The reaction is exothermic.
- Only option C contains Hydrogen and Carbon.
