From point W to point Z, the ball is B- Potential energy was transformed to kinetic energy. We know this because, at point W, the ball is in its potential form, it has the potential to roll but it has not yet started to. As we let the ball go, we turn that potential energy into kinetic energy, which is the energy that it has due to its motion.
I hope I've helped! :)
B) exocytosis : exo- means out, cyto- means cell, and -sis means condition, therefore you have something coming out of a cell

Chromosomes exchange genetic material in step 3.
<h3><u>Explanation</u>:</h3>
The meiosis is the type of cell division that takes place for gametogenesis. The meiosis has two phases - meiosis I and meiosis II.
The meiosis I has the events like crossing over and independent assortment which leads to the mixing of genes between homologous chromosome pairs and separation of homologous chromosome pairs. So the two cells that are produced from the meiosis I are genetically different. The step 3 shows the crossing over of prophase 1 of meiosis I. So, it shows the genetic difference between the offsprings and leads to genetic variation.
