Pollen is a gamete therefore it contains half genetic information of a regular cell. all the possible combination types are S1T, S2T, S1t and S2t
Answer:
The correct answer is - altered primary and quaternary structure; secondary and tertiary structure may or may not be altered.
Explanation:
a) Primary structure: It is fundamentally the amino acid sequence or arrangments. Every protein has a remarkable amino acid sequence and little change in these sequence modifies the primary structure. On account of sickle cell, the amino corrosive has changed, and henceforth the essential structure of the protein molecule changes.
b). secondary structure: It is the folding of the primary structure chain, which results from intermolecular and intramolecular hydrogen holding of the amide group. Ex; Alpha helix and beta sheets. In the above case, this may or might not have changed as there is no conclusive method to know this.
c) Tertiary structure: Most proteins' tertiary structures are mixes of a-helices, b sheets, and circles and turns. Every protein has interesting three-dimensional structure, folded in a particular way now and then known as a domain. For our situation, since it depends on the optional structure, it might have changed.
d) Quaternary structure: It is the relationship of numerous individual protein chains into a solitary protein with various subunits. The subunits arrangment offers to ascend to a steady structure. For our situation, a hemoglobin tetramers partner with one another and gather into large fibers. This has changed the first structure and accordingly we state the quaternary structure has changed.
The right answer is foods that are high in fiber.
Alcohol passes into the esophagus and ends up in the stomach. 20% of this alcohol crosses the wall of the stomach to end up in the blood. Then the alcohol left in the stomach passes into the small intestine, which assimilates it quickly. The liver partly breaks down the alcohol that has passed into the bloodstream.
Alcohol reaches the brain, after about 10 minutes, through the blood. It is then that this part of the body and the nervous system undergo the effects (narcotics). The assimilation of alcohol lasts longer if The person is not fasting at that time (it will be necessary to avoid carbohydrate-based foods and to favor fatty and protein-rich foods to attenuate the absorption).
