Answer:
zero
Explanation:
Displacement is a vector, meaning that the direction is very important. Displacement is the distance from the starting point to wherever the object is. So a car that does a 500 m lap will have covered 500 m in distance but displacement is zero because, having come back to the starting point, the distance between the starting point and where the object is, is zero.
Answer:
The sine or sin is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse).

Explanation:
Answer:
1) By 11:30pm
2) Shortly before midnight (few minutes to 12:00am)
Explanation:
Since the strain of bacteria takes 1 minute to divide (double its population), and by midnight (12:00am) the entire bottle becomes full, then:
I) Subtract Initial division time from Final division time i.e 12:00 - 11:00 = 1 hour
II) Split 1 hour into two (60minutes makes 1 hour)
I hour/2 = 30 minutes
Definitely, the bottle will be half filled by 11:30pm
2) Once half filled, the rapidly dividing cells reach for the top of the bottle as midnight approaches. By 11:50pm upwards, bottle space must have been running out
Answer:
A. Species
Explanation:
Species is the most specific level of classification in taxonomy.
One mnemonic that can be used to remember the order of ranks is:
Dear King Philip Came Over For Good Soup
This stands for domain, kingdom, phylum, class, order, family, genus, species.
And, this is in order of the most broad to the most specific rank.
So, A is the correct answer.
Changes in the gene pool are closely related to genetic mutations, which are a major part of evolution.
