A person who specializes in the study of animals is called a zoologist. Zoologists who study certain kinds of animals have their own names.
Answer: A protein domain is a region of the protein's polypeptide chain that is self-stabilizing and that folds
independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains.
One domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions.
In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length.
The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium binding EF-hand domain of calmodulin.
Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins.
Answer:
becuase plants make up surrounding areas, if you see no plants and soil with no fertilization from plants it is most likely a desert, and a place with tall and thick plants is most likely a forest
A good index fossil is one with four characteristics: it is distinctive, widespread, abundant, and limited in geologic time. Because most fossil-bearing rocks formed in the ocean, the major index fossils are marine organisms
Sulfuric Acid is a diprotic acid and as such a binary acid. This is because it possesses two hydrogen as denoted by its formula H₂SO₄
Hydrochloric Acid - HCl
Phosphoric Acid - H₃PO₄
Nitrous Acid - HNO₃
