Explanation:
Options for the question
- car a and car b are both moving toward the origin.
- car a and car b are moving in opposite directions.
- car a is moving faster than car b.
- car a and car b started at the same location.
- car a and car b pass each other at the crossover point on the graph. time (s)
Solution -
The motion of any object is represented by position-time In such graphs the position of an object is fixed for any starting point on the y-axis and time on the x-axis.
The slope of such curves determine the velocity of the object at all its position within the graph. The steeper the slope is, the faster the the object is moving.
Hence, the following statements are correct
Option 1, 2, 5
Proxima Centauri is the nearest star to Earth.
Identical twins are formed through the process of meiosis where a fertilised egg separates to form two identical cells with a common genetic information.
Fraternal twins on the other hand are developed from the fertilisation of two different eggs and two sperm cells. This type of twins possess unique genetic information.
E . all of the statements are true hope i’m correct

Explanation:
Chromosomal inversion is a situation involving the segment of a chromosome where it is turned upside down and reinserted back into the chromosome. This usually occurs because of a breakage and rearrangement occurring within a single chromosome.
It is of a two types, these are
* Paracentric chromosomal inversion - a type where a segment not including the centromere is snipped out, inverted, and inserted back to its location on chromosome.
* Pericentric chromosomal inversion - is a type where a segment including the centromere is snipped out, inverted, and inserted back to its original location on chromosome.
