Which of the following real-world examples models linear motion? a. throwing a rock in the air at a 60-degree angle b. running around the curve of a track c. throwing a rock in the air at a 45-degree angle d. running 50 m along a straight track

D. Running 50 m along a straight track

Explanation:

Running 50 m along a straight track is a real-world example of linear motion.

Linear motion means moving along a (straight) line, a direct and straight line from point A to point B.

All the other proposed answers (A,B,C) involve a curve.  The two rock examples will curve due to gravity and running around a curve on a track isn't a straight line.

I hope that helps you understanding the principle of linear motion.

the answer is "meiosis ii in the mother".

the procedure of meiosis includes two divisions of the hereditary material. the main division is known as the decrease division – or meiosis i – on the grounds that it lessens the quantity of chromosomes from 46 chromosomes or 2n to 23 chromosomes or (n depicts a solitary chromosome set). in people, the decrease division results in two sperm cells each with 23 chromosomes or an egg cell with 23 chromosomes and one disposed of polar body. the second division – or meiosis ii – is called equational division. the two sperm cells split again creating four sperm cells, each with 23 or n chromosomes. in oogenesis, the egg cell and polar body partition to shape the ovum and two extra polar bodies. along these lines, the posterity are guaranteed to get one portion of the chromosomes from the mother and one half from the dad.
