Answer:
Contains large polytene chromosome that permit visual inspection of genomic events.
Were used to study the genetic effects of mutations.
Were used to establish the concept of chromosomal inheritance.
Explanation:
<em>Drosophila melanogaster </em>is a model organism that is used by scientists to study the genes and effect of a mutation on the genes. Drosophila is used as a model organism as it has a very short life cycle and the offspring can be produced in a short duration of time.
Because of these characteristics, Thomas Hunt Morgan wanted to study the factors of inheritance on the <em>Drosophila</em> and concluded in the form of the chromosomal theory of inheritance by the effect of mutation on genes that lead to linkage mapping.
Also, the salivary gland of fruit fly contains the polytene chromosome which allows us to look into the gene events.
Thus, the selected options are correct.
Epigeal germination is a botanical term indicating that the germination of a plant takes place above the ground. An example of a plant with epigeal germination is the common bean. The opposite of epigeal is hypogeal.
The names of most enzymes end in "-ase." Some enzymes which have been known longer have older names that don't end in "ase." For example: pepsin, trypsin, and chrymotrypsin which are all enzymes localized in the digestive tract. hope u got the point
The repository of bile produced by the liver is one of the gallbladder's top priorities.
Bile is required to break down the body's fats and lipids, making it vital for digestion. In addition, it helps in the metabolism of bilirubin, which is produced when RBCs break down.
The gallbladder serves several essential purposes, including the following:
- The ability to empty and restock its bile reserves in response to intestinal hormones like cholecystokinin.
- To assist in controlling the bile's chemical makeup (the percentage of water, bile salts and more)
- To regulate the small intestine's bile flow.
- To contract (secreting bile into the biliary tract and duodenum)
