The correct answer is taxonomy,
Taxonomy is a branch of biology that aims to to sort living thing into categories. In its early years, taxonomy was solely based on structural comparisons, mostly the anatomical similarities and differences between the organisms. However, with the discovery of the physiological processes and the genetic structures of organisms, the previous taxonomic knowledge was revised and changed in the light of the new scientific finds. Nowadays, taxonomy is primarily based on genetic similarities between the organisms.
I need the answer to!!!
True or False
A. Hormones modify cellular activity.
B. Hormones are secreted into the bloodstream.
C. Hormones produce a change in animal behavior.
D. Hormones attach to receptors on the cell surface.
E. Hormones are released in response to external stimuli.
The coiling direction of the snail shell is affected by the maternal genes. All the offspring have left-coiled shells, as the phenotype is determined by the mother's genotype. Thus, option C is correct.
Maternal inheritance has been defined as the effect by which the genes are influenced by the mother's genotype and are a type of non-Mendelian inheritance.
The dextral and the sinistral coiling seen in the snails showing the maternal effect is influenced by the genotype of the mother and is not affected by the father's genotype.
The mother has the cc and the father has the CC genes that when crossed are shown in the image.
From the cross, it is evident that the genotype of the mother snail affects and influences the genotype of the offspring, and hence all the offspring's have the left coiling (sinistral).
Therefore, in option C, the genotype of the mother snail affects the coiling.

Your question is incomplete, but most probably your full question was,
All of the offspring have shells that coil to the left. Why do all of the offspring have left-coiled shells?
A. This trait follows a typical Mendelian pattern of inheritance.
B. Only the father's genotype determines the phenotype for shell coiling.
C. Only the mother's genotype determines the phenotype for shell coiling.
D. Shell-coiling is a sex-linked trait.
B. The effects of a disease on population size
C. The effects of an invasive plant species on bird nesting sites
D. The effects of competition on survival
