The part of the amino acid that gives the molecule its unique or characteristic chemical properties would be the R-group. Every amino acid has three main groups in it namely the amino group, carboxyl group and the R group. "R" represents different organic chain that is specific to a certain amino acid which gives different properties of the molecule.
Answer:
Explanation:
middle of a food web includes small animals, such as worms or jellyfish. But also many fish species like menhaden . Think of these organisms like a bridge — they take the energy produced by the lower food web and make it available to the top food web.
Answer: a. encode transcription factors that control the expression of genes
Explanation:
Homeotic Genes - They encode transcription factors that determine the location at which specific structures develop. They give organs identity. Homeotic genes act as regulators of development and some mutations found in flies were instrumental in unraveling the macroevolution related mysteries.
Mutations in homeotic genes are often fatal in the early stages of development, however viable mutant flies with strange aberrations have been found, such as the discovery of Antennapedia mutants, in which paws are formed in place of antennae. Homeotic genes regulate the development of specific embryonic segments and are fundamental, among other functions, in determining the anteroposterior axis of metazoans. When we compare flies and humans, homeotic genes resemble both their nucleotide sequence and their relative position on chromosomes.
Answer:
Due to no jaws, no paired fins and scales on the body.
Explanation:
Pteromyzon fish is different from scolidon and labeo fishes because Pteromyzon fish is not a true fish. The main reason for this is that Pteromyzon fish is agnathous means having no jaws and it doesn't have paired fins and scales on their body while all these features are present on the body of scolidon and labeo fishes so we can conclude from this discussion that Pteromyzon fish is different from scolidon and labeo fishes.
