Modelling refers to using a diagrammatic representation to present a particular event or biological activity.
The two maps shown are very good for representing/modelling mitosis.
Advantages
- They clearly lists the various steps involved in mitosis and as well included the process of cell division starting from the interphase stage (for the second diagram).
- The M phase was also clearly explained in the first diagram.
Disadvantages
- The first pictorial diagram had to labelling to depict the name of each particular phase and makes understanding difficult.
- The second diagram fails to show pictorial representation of what could have exactly happened in each stage in the process of cell division.

Answer:
chemical reaction:-
12H20 + 6CO2 + light =====> C6H12O6 + 6H2O + 6O2
the above reaction shows that if we combine water,carbon dioxide and sunlight ,the resultant products will be glucose ,water and oxygen .
The plant converts the carbon dioxide into energy and oxygen by different steps that include
- absorption of light
- conversion of NADP into NADPH+
- conversion of ADP into ATP
- formation of carbohydrates from CO2 !
Renewable is more reliable and not a liability ther you go
Answer:
Timeline. In a temperate climate, it usually requires three weeks to several years for a body to completely decompose into a skeleton, depending on factors such as temperature, humidity, presence of insects, and submergence in a substrate such as water.
Explanation:
The three different processes that are occurring in the above drawing are:
1. Process A: Diffusion.
2. Process B: Facilitated diffusion.
3. Process C: Active transport.
Cell transport refers to the movement of ions, molecules, or substances across the cell membrane, either into or out of the cells of a living organism.
From the above diagram, the three (3) different processes that are occurring are:
1. Process A: Diffusion.
- Diffusion refers to the movement of gas molecules from a region of high concentration (top) to a region of lower concentration (bottom) until an equilibrium is attained or reached.
2. Process B: Facilitated diffusion.
- Facilitated diffusion refers to the movement of substances or gas molecules across a cell membrane from a region of high concentration (top) to a region of lower concentration (bottom), especially through the help of transport protein.
3. Process C: Active transport.
- Active transport involves the movement of substances across the cell membrane from a region of lower concentration to a region of higher concentration, against a concentration gradient and in the presence of oxygen.
