1 : Canadian Shield - tundra.
This means that it's characterized by low temperatures which stop and limit plant growth. It's similar to the desert, except it has more precipitation
2 : Alaskan plains - subarctic
Due to its closeness to the arctic.
3 : Seattle, Washington - Marine west coast (West Coast of the Pacific Ocean - the closeness of the ocean has a determining influence on the climate)
4 : Washington, D.C. humid continental climate, with mild but wet winters
When a person watches television for a long stretch of time in order to observe and then, record the total aggressive incidents occurring during that period is a good example of the rate measure of the behavior. The rate measure refers to the measure of the frequency of the concerned events occurring in the defined period of time. Since, the person is looking for the aggressive behavior on television during his four hour watching, this is a rate measure.
Explanation:
the food u eat will goes from oesophagus to ur stomach and then it is mixed by hcl present in your stomach that makes the medium acidic for pesin to digest protein and then bile juice from liver makes the medium alkaline and breaks the larger globules of carbohydrates for enzymes then the food goes goes to small intestine that secretes intestinal juice that converts carbohydrates into glucose
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.
