Answer:
Lack of food sources, the lack of habitat, competition and evolving ways to compete.
Explanation:
Lack of food sources, the lack of habitat, competition and evolving ways to compete are the ecological conditions that is responsible for the rapid diversity of some lineages. With the passage of time, changes occurs in the lineages due to climate change which causes some species to extinct and some to evolve which attains adaptability to the environment. Due to climate change food is unavailable to the organisms which is the main cause of its extinction.
Answer:
I believe the answer is:
They both have different phosphate groups in their backbones
Possible Genotypes: WW, Ww, ww
Possible Phenotypes: Has widow's peak or doesn't have widow's peak.
Answer:
A and F are phosphate groups.
B and E are sugars.
C and D are nitrogenous bases.
Explanation:
Nucleotides are the molecules responsible for composing DNA and RNA. They are formed by three units: a phosphate group, a sugar molecule and a nitrogenous base.
The sugar molecule is a pentose, which means that it is a molecule formed by 5 carbons. These collections are represented by geometrical figures such as the letters "B" and "E" shown in the figure above, where each tip represents a carbon.
The nitrogenous bases are molecules that are named adenine (A) and guanine (G) and the pyrimidine bases cytosine (C), uracil (U) and thymine (T).
The phosphate group, in turn, is a molecule derived from phosphoric acid and is the only one that does not vary in each nucleotide.
