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.
4. E=mc²
Explanation:
The best approximation of the energy released during a nuclear fusion process can best be determined using the Einstein equation.
In nuclear reactions, mass and energy are equivalent:
E = mc²
E is the energy
m is the mass
c is the speed of light
- In nuclear reactions, some of the mass is converted into the energy.
- Therefore mass is not conserved in such equations.
- This is why they release huge amount of energy.
- From this equation, we know that the more mass loss, the more the energy that would be produced.
- In a fusion reaction, two light nuclei combines to form a heavier one.

Basically no one knows that an earthquake is coming until it's happening.
People don't have time to evacuate because they don't know that an earthquake is going to take place , in other words the earthquake takes them by surprise.
A) causes an effector to signal the control center of an organism, which creates the stimulus to make a response
