Katena32 [7]

Answer:

Zooplankton -tiny aquatic habitat organisms- gets their energy from phytoplankton consumption.

Write a 2 paragraph summary about the structure of DNA from the information on the first page.
mote1985 [20]

Answer:

DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. For example, the sequence ATCGTT might instruct for blue eyes, while ATCGCT might instruct for brown. The complete DNA instruction book, or genome, for a human contains about 3 billion bases and about 20,000 genes on 23 pairs of chromosomes.

You discover a genus of lizards that contains two extinct species and five living species. The oldest fossils from the genus bel
Crank

Answer:

The evolution of the species might occur due to the change in the environmental conditions and the mutation in the organisms. The organism that can adapt in the environment will survive better.

The lizard species is present in the Ethiopian biogeographical region but now its two living species is in Neotropical biogeographic region and three species is in Australian biogeographic region. This might possible due to the fact that Neotropical and Australian lineages might have the common ancestor that were earlier originated in the Ethiopian region. The continental drift might have occur that breaks the Ethiopian biogeographical region and the species are present in the different island.
