The answer is cross-pollination, by using parents that had different traits.
Gregor Mendel researched pea plants and he <span>established the principles of heredity. To explain his experiments and discoveries, he invented terms dominant and recessive in reference to traits. In his experiments, he used cross pollination which includes the crossing of parents with different traits. For example, he crossed a plant with green peas and a plant with yellow peas (two different traits) and studied how these traits are inherited to the next generation.</span>
Answer:
The tryptophan synthase enzyme catalyzes the synthesis of tryptophan. This enzyme is found in all kingdoms except animals.
Tryptophan synthase has a hydrophobic channel that facilitates the passage of an intermediate from one enzyme to the other during the biosynthesis of tryptophan, which makes faster the metabolic process.
Answer:
An efficient way to search for and insert a value in a cell when the desired value is stored elsewhere in the worksheet or even in a different workbook is by using lookup functions.
Explanation:
- Lookup function is the built in function of excel that helps in returning the certain value form specific row or column.
- When the value is stored in the worksheet we can easily insert that desired value in the cell by the use of lookup functions.
- VLOOKUP and HLOOKUP are the lookup unctions that searches the value in column and row respectively.
During gas exchange, the cell membrane of a single-celled organism has the same function as the respiratory system in humans. The respiratory system is a biological system which is composed of specific organs and structures such as nose, pharynx, larynx, trachea, bronchi and lungs that are used for gas exchange in humans. The primary function of the respiratory system is to transport oxygen into the body and to breathe out carbon dioxide, which is a waste product of cellular function
