All liquid glow products depend on a chemical process known as CHEMILUMINESCENCE to produce their light. ... When the stick bends, the glass vial breaks allowing the two liquids to mix together. The chemical reaction begins immediately resulting in a bright, fantastic glow.
Answer:
B- A cleft chin is due to a dominant allele
Explanation:
A husband and wife both having the phenotype for cleft chin and producing an offspring without a cleft chin, indicates heterozygousity in their genotype.
With the heterozygous genotype however, they both expressed the phenotype for cleft chin, indicating that the allele for cleft chin is dominant over the allele coding for normal chin.
Since both parents are heterozygous for cleft lip, the sequence of genotype in their offspring will be:
- 25% chance of having homozygous cleft chin
- 50% chance of having heterozygous cleft chin
- 25% chance of having homozygous normal chin
Because of the dominance of the cleft chin allele, both homozygous and heterozygous forms of the cleft chin allele, will be expressed in the offspring and only the offspring homozygous for normal chin will not express this allele.

Answer: option B) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population.
Explanation:
Sympatric speciation is an event/situation whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e do not live in geographical isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory to yiels new species or offsprings that are genetically different from their parents, and causing uneven gene flow or disruption of alleles known to have been prevalent among the parent organisms
So, only option B is true
