I believe this would be true
Answer:
False
Explanation:
Approximately 200 out of 200 million sperms ejaculated during intercourse reach the general vicinity of the egg. They sperms must undergo capacitation during which dilute inhibitory factors fluids of the female reproductive tract weaken the membrane of the sperm head so that head of the sperm can be broken easily when it came in contact with the egg.
The first sperm to reach an egg isn’t the one to fertilize it because the egg is surrounded by a gelatinous membrane called the zona pellucida. Outside this layer, a layer of small granulosa cells also present.
Therefore, it requires numerous sperm to clear a path through these barriers before one of them can penetrate the egg and fertilize it.
Answer:
The correct answer is - aerial view of the fault line of San Andreas which represents a transform or strike-slip type of boundary.
Explanation:
The picture is given in the question is an aerial view of the fault line of San Andreas.
A fault is a planar break or intermittence in a volume of rock across due to rock-mass movement that leads to significant relocation or displacement. In San Andreas, the faultline represents the transform or strike-slip type of boundary.
Observation:
- A complex zone of crushed and broken rock
- Many smaller faults branch

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.
