You are growing plants hydroponically (rooted in an aqueous solution rather than soil). The solution for the control group of pl
ants contains normal levels of salts and nutrients, while the solution for the treatment group has a high concentration of large molecular weight solutes that are excluded by roots. You find that the plants in the treatment group are, on average, smaller than those in the control group, but there is no significant difference between the groups in the amount of CO2 being fixed by the average plant. What differences between groups, at the cellular level, would you expect to make an important contribution to the difference in size of the shoots
Explanation:Mendel's first law (also called the law of segregation ) states that during the formation of reproductive cells (gametes), pairs of hereditary factors (genes) for a specific trait separate so that offspring receive one factor from each parent.
Embryos of different vertebrate groups are morphologically similar during the early stages of development. The closer the resemblance between the early stages of different organisms, the closer their evolutionary relationship. Such similarity suggests a common ancestry.
