B, hormones that serve as chemical messengers im not 100% sure though
Answer:
Dominant allele does not completely conceal recessive allele.
Snapdragon with genotype Rr (R being red and r being white), would have a phenotype of pink flowers.
Explanation:
Incomplete dominance is where a dominant allele is not able to completely conceal a recessive allele, usually leading to a phenotype which appears to be a combination of the two.
For example, in snapdragons:
The allele for red flowers (R) is dominant over the allele for white flowers (r). Let's say a snapdragon flower had the genotype Rr, one allele for red flowers and one for white. In the case of 'normal' dominance the dominant red flower allele (R) would mask the effects of the recessive white flower allele (r), resulting in the phenotype (outward observable characteristics) of having red flowers.
However here in the case of incomplete dominance, the dominant allele would not be able to fully cover up the effects of the white flower allele, meaning that both colors (red and white) are expressed in the phenotype, resulting in pink flowers.
Hope this helped!
Answer:
Insecta
Explanation:
The classification levels are the following from broadest to the most specific:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
In your selection it is listed in that order:
Domain --- Eukarya
Kingdom --- Animalia
Phylum --- Arthropoda
Class --- Insecta
Order --- Hymenoptera
Family --- Apidae
Genus --- Apis
Species --- Mellifera
When you name the organism, we use the two name or binary naming system, getting the genus and the species. So the scientific name of the honey bee is: Apis mellifera
