Answer:
Explanation: If the high tide is higher than usual, and the same thing for low tides, it is a spring tide, because it is strong. Two weeks later, he observed a neap tide, because there is not much difference. The tides get weaker and stronger because the moon changes positions. The gravitational pull is affected differently. The Earth also changes positions, so it also has an effect, but the moon has the most powerful.
<span>The crossed flies are heterozygous so they have one allele of each for the characteristics. So the genotype is Bb for body color and Rr for eye color.
To set up the punnett square, you would determine all possible combinations for the alleles that each parent could provide: BR, Br, bR, and br. Then make the table, and combining the rows and columns:
BR Br bR br
BR BBRR BBRr BbRR BbRr
Br BBRr BBrr BbRr Bbrr
bR BbRR BbRr bbRR bbRr
br BbRr Bbrr bbRr bbrr
There are sixteen combinations of the genotypes and they need to be classified: BB or Bb- Brown body; bb- black body; RR or Rr- red eyes; rr- brown eyes
Brown body and red eyes- 9
Brown body and brown eyes- 3
Black body and red eyes- 3
Black body and brown eyes 1</span>

Answer:
18 is the nuclesus, 20 is the smooth endoplasmic reticulum and 21 is the golgi apparatus and 19 is the microtubes and 17 is the vacules.
Explanation:
Answer:
0.095
Explanation:
Phenylkentonuria is a disease caused by a recessive allele.
The frequency of the recessive allele + the frequency of the dominant allele equals 1.
The frequency of the recessive allele is q = 0.05
The frequency of the dominant allele then is p = 1 - q = 0.95
If people mate randomly, the frequency of the homozygous dominant genotype will be p², the frequency of the heterozygous genotype will be 2pq and the frequency of the homozygous recessive genotype will be q² .
2pq=2× 0.05 × 0.95
2pq=0.095
The heterozygote frequency in the population is 0.095
