Answer:
A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.
Explanation:
The statement which is true is as follows:
- As evidence changes, scientific theories can also change.
Thus, the correct option is A.
<h3>What is Scientific theory?</h3>
A Scientific theory may be characterized as a well-determined description of some features of the natural world, based on a body of certainty that has been repeatedly assured through observation and experiment.
Scientific theories describe the natural world, while scientific law explains natural phenomena. It is not assumed that if a single study or inference is wrong, a scientific theory can be invalidated. It undergoes a series of protocols before rejection.
As evidence is modified or changed, the scientific theories can also be altered on the basis of it.
Therefore, the correct option for is question is A.

According to the given statement The volume in cubic feet rounded to 3 significant digit is 4022.34 cu ft.
<h3>What is volume and example?</h3>
The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.
<h3>Briefing:</h3>
Slant height = 15.25 feet=2196 inch
Smaller base diameter is = 12.00 inches r = D/2 = 6 inch
Larger base diameter is = 24.00 inches r = D/2 = 12 inch
h = √s² - (r
- r
)²
h = √(2196)² - (12 - 6)²
h = 2195.99
V = 1/3π h(R² + r² + Rr)
V = 1/3 * 3.14 * 2195.99 (144 + 36 + 72)
V = 579216.96 inch
V = 579216/144 = 4022.34 cu ft.

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.
