Answer:

Phenotype frequency ( widow's peak ) = 0.5

Phenotype frequency ( straight hairline ) = 0.5

Genotype frequency ( Ww ) = 0.5

Genotype frequency (ww) = 0.5

Allele frequency ( W ) = 0.25

Allele frequency ( w ) = 0.75

Explanation:

Given, Widow's peak (W) is dominant over straight hairline (w).

Parent 1: heterozygous dominant = Ww

Parent 2: homozygous recessive = ww

When Ww X ww :

     W      w

w  Ww   ww

w  Ww   ww

Half of the offspring are Ww and other half are ww so genotype frequency of Ww is 0.5 and of ww is 0.5. Phenotype ratio for widow's peak (Ww) is 0.5 and for straight hairline (ww) is 0.5.

Allele frequency = Number of that allele / Total number of alleles

f(W) = 2 / 8 = 0.25

f(w) = 6 / 8 = 0.75

Anna007 [38]
For me I love gaming but at the same time I have homework. So it is hard for me and I'm going through it right now but improving me. You must first think which one is important. Like is gaming important over homework or homework importance over gaming? You might choose the second one, why? It is really simple, you must first think about it.

Alisiya [41]

Answer is a. he projections are trichocysts, released for the self-defense of the <em>Paramecium</em>.

When <em>Paramecium</em> is stimulated by chemicals such as picric acid or an injurious enemy, it responds by throwing out transparent spine-like projections called trichocysts. The discharge of trichocysts forms an effective barrier round the animal and protects it from acid or enemy.

Maurinko [17]

Answer: amplitude would help measure height

low f, constant speed, long wavelength

speed = frequency x wavelength

Explanation: constant speed, low frequency

frequency = speed/wavelength; at constant speed f proportional to 1/wavelength, so low f __> long wavelength

speed = freq*wavelegth
