34. john wants to build a racetrack that will allow his toy cars to travel fast when force is applied. which material should he use?\na) gravel, because friction will be high b) carpet, because friction will be high\nc) sandpaper, because friction will be d) plastic, because friction will be low\nlow\n35. which occurs in high - pressure systems?\na) the formation of tornadoes b) large clouds, as air rises\nc) the formation of hurricanes d) calm weather, as air sinks\n36. how does mitosis compare to meiosis?\na) mitosis only occurs in single - celled organisms, while meiosis only occurs in animals.\nb) mitosis produces two identical daughter cells, while meiosis produces sex cells with half the genetic information.\nc) mitosis produces sex cells with half the genetic information, while meiosis produces two identical daughter cells.\nd) mitosis only occurs in animals, while meiosis only occurs in single - celled organisms.

Answer

# Brief Explanations: - For question 34: To make toy - cars travel fast, we need low friction. Plastic has lower friction compared to gravel, carpet, and sandpaper. - For question 35: In high - pressure systems, air sinks, leading to calm weather. Tornadoes and hurricanes form in low - pressure systems, and large clouds form when air rises (in low - pressure or other lifting mechanisms). - For question 36: Mitosis produces two identical daughter cells and occurs in both single - celled and multi - celled organisms for growth, repair, etc. Meiosis produces sex cells (gametes) with half the genetic information and is mainly involved in sexual reproduction. # Answer: 34. d) plastic, because friction will be low 35. d) calm weather, as air sinks 36. b) Mitosis produces two identical daughter cells, while meiosis produces sex cells with half the genetic information.
