B, the others are not testable under lab conditions.
<span>Aside from absorbing water and nutrients in the
ground, roots are also the very support of a tree. It supports bigger trees to
stand and stay steady against heavy rains and strong winds. Roots are also
capable of absorbing water that may cause flood in the area, and support slopes
that may result to landslides. Roots are very important because it lessen the
chances of soil erosion in a certain place. Roots can also be used for plant
vegetations.</span>
In parthenogenetic reproduction, the egg cell develops into a new or ganism without fertilization. It is clear that the most essential feature of parthenogenesis, absence of fertilization, causes important alterations of basic nature in cytological, as well as in genetic, respects.
Answer:
- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.
- The solutions are hypotonic to the solution in the potato cells.
Explanation:
According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.
Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.
