Answer
  • Normal cells have 1/2 the chromosomes of a sex cell
  • Normal cells have the same number of chromosomes as sex cells
  • Sex cells are produced by mitosis
  • Sex cells have 1/2 the number of chromosomes of normal cells

Question 29

Question
Which of the following statements about mutations is false
Answer
  • Mutations are changes to genes
  • Mutations are always harmful to an organism and result in sickness or death
  • Some mutations result in changes that are beneficial to an organism

Answer
  • A population can change over time in response to environmental pressures

  • Natural selection is a process whereby genes are selected randomly for preservation to the next generation.
  • Natural selection favours individuals that reproduce more than others
  • Natural selection can be used by farmers to generate organisms with desirable trains

Question 32

Question
The process of promoting certain traits by breeding members with those traits is [blank_start]artificial[blank_end] selection
Answer
  • artificial

  • variation

Question 34

Question
Newton's First Law states that an object will remain at [blank_start]rest[blank_end] or in uniform motion in a straight line unless acted upon by an [blank_start]external force[blank_end] Newton's Second Law states that [blank_start]acceleration[blank_end] is produced when a [blank_start]force[blank_end] acts on a [blank_start]mass[blank_end]. The greater the mass (of the object being accelerated) the greater the amount of [blank_start]force[blank_end] needed (to accelerate the object). The formula created from this was [blank_start]F=MA[blank_end] Newton's third law states that for every [blank_start]action[blank_end], there is an [blank_start]equal[blank_end] and opposite [blank_start]reaction[blank_end]
Answer
  • rest
  • external force
  • acceleration
  • force
  • mass
  • force
  • F=MA
  • action
  • equal
  • reaction
