Review Questions 3. Animals benefit from the relationship with plants because they are able to get rewards such as pollen and nectar. With these they have the ability to continue on with their daily work. Applying Your Knowledge 1. The rise in prominence of one major group does not necessarily result in the total replacement of a previously dominant group because one group may work better in the part than the other group. Gymnosperms for example produce excess amount of pollen‚ they are

Experiment 9/5 Voltaic cells AIM How the change the concentration of the electrolyte CuSo4 (solution of ions) affect the voltage of the electrochemical cell BACKGROUND An electrochemical cell is also called a voltaic cell‚ which derives electrical energy from redox reaction taking place within the cell. It consists of two different metals that are connected by a salt bridge. Eletrons always flow from anode to cathode‚ where anode is negative (reduction) and cathode is positive (oxidation)

BGY 2001 CONCEPT OF BIOLOGY Laboratory Report PRACTICAL 8 TRANSPIRATION Tittle: Transpiration Objectives: 1. To measure transpiration rates by using photometer. 2. To determine the factors that influences the rate of water loss from a plant through transpiration Introduction: Most of the water a plant absorbs is not used for a plant’s daily functioning. It is instead lost through transpiration‚ the evaporation of water through the leaf surface and stomata‚ and through guttation

1Achievement Standard Biology 91155 Demonstrate understanding of adaptation of plants or animals to their way of life Biology 2.3A 3 credits All animals including insects‚ fish‚ and mammals have adaptations in some form of internal transport that allow them to carry out their way of life. Adaptations such as the different structures of the transport of nutrients and wastes‚ the gas exchanges‚ and the support and movement of the animal all take part in how each of the different animals operate
