Explanation of Solution

There have been various factors that enabled plants to evolve from living in water to living in land.

  • The development of waxy layer and cuticles help to retain water in plants and prevent water loss. This feature enabled them to survive in dry habitat.
  • To retain water and exchange gases small pores called stomata developed. These pores can open and close depending on weather conditions. Stomata close to retain water inside and open when weather cools down.
  • The development of embryo inside of the female plants after fertilization makes them reproduce in dry conditions, whereas algae release their embryo in water.
  • Development of vascular tissue called xylem and phloem in plants provides transport of water and nutrients up into the plant and food down from leaves to rest of the plants.
Conclusion

Factors which played a role in enabling plants to survive on land includes cuticle layer, stomata, embryo development and development of Xylem and phloem.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
