Answer: 101 neutrons
An element's atomic number is the number of protons in its nucleus. X has 52 protons. The mass number is simply the number of protons AND neutrons in the nucleus. Since 52 is given, it's correct to assume that the remainder consists of neutrons. 153-52 will give you the number of neutrons.
Hope this helps! :)
Answer: The food chain
Explanation: It is important to have a large number of producers and herbivores in an ecosystem because of the food chain. Without producers the herbivores would have no food. and without the herbivors the carnivores would have no food.
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.
<span>One molecule of glucose can yield 36 ATP after glycolysis and aerobic respiration.
This question is a bit tricky. Glucose can produce a total of 38 ATP after glycolysis in aerobic respiration but it will need</span> 2 ATP because you need ATP to move NADH to mitochondria <span>so it will yield net amount 36 ATP.
Sometimes, </span>2 ATP in the preparatory phase is also subtracted resulting in 34 ATP.
