The answer should be false.
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.
Because there are 23 chromosomes in the haploid cells. Chromosomes from each haploid cell (sperm/egg) come together to from a diploid cell, meaning that the 23 chromosomes from the sperm have intermixed with 23 chromosomes in haploid cells of the egg so this is you answer hope this helped
Answer:
180seconds
Explanation:
According to the question, Kepler-186f is an exoplanet that orbits a star called kepler-186, other than the Sun.
Distance of the star (kepler-186) away from the planet is 5.4 x 10^10 meters
In order to calculate how long i.e. time, a light moving at an average speed of 3.0 x 10^8 m/s will get to the exoplanet from the star, we use;
Speed (m/s) = Distance (m) ÷ time (s)
Time = Distance/speed
Time = 5.4 x 10^10 ÷ 3.0 x 10^8
Time = 5.4/3.0 × 10^ (10-8)
Time = 1.8 × 10^2
Time = 180seconds.
The correct answer for the question above is letter a. <span>It takes up space and has mass. It is the best statement that describes all types of matter. The other choices refers to specific groups of matter. I hope I have answered your question.</span>
