<h3><u>Answer;</u></h3>
Label A; Mitochondria.
Label B; Nucleus.
Label C; Golgi apparatus.
Label D; Rough endoplasmic reticulum
<h3><u>Explanation;</u></h3>
- All the above are various organelles in a eukaryotic cells each carrying different cellular activity to enhance the functioning of a cell.
Label A; Mitochondria.
- <u>Mitochondria</u> is the powerhouse of the cell which converts glucose to energy rich molecules of ATP, through the process of cellular respiration.
Label B; Nucleus.
- <u>Nucleus</u> contains the genetic material or DNA, RNA , nucleolus, chromatin fibres and proteins. It contains the chromosomes which control the hereditary characteristics.It also regulates all the activities of the cell.
Label C; Golgi apparatus.
- <u>Golgi apparatus;</u> they are also called Golgi bodies. They function in modifying, sorting and packaging of proteins for secretion. They are also involved in the transport of lipids around the cell, and the creation of lysosomes.
Label D; Rough endoplasmic reticulum
- <u>The rough endoplasmic reticulum</u> provides surface for protein synthesis. It is also used to transport cellular contents from one cell to another.
- The risbosomes attached on the rough endoplasmic reticulum are resposible for the protein synthesis through the process of translation.

Explanation:
Nitrogen is vital for the physiological processes of plants. Nitrogen can be supplied to the plants in the form of nitrogen fertilizers. Though nitrogen is plenty in atmosphere, plants cannot use it and it should be converted into assimilable forms of nitrogen. This is done by the process of nitrogen cycle which includes the nitrogen fixation, ammonification, nitrification and denitrification.
The conversion of the atmospheric nitrogen into useful organic compounds by bacteria or the industrial process is called nitrogen fixation. These organic compounds are then converted into ammonia which can be assimilated by the plants through microbes by a process called ammonification. Ammonia is then converted to other assimilable form called the nitrates by nitrification mediated by bacteria. The nitrates formed is reduced back to nitrogen gas by a process called denitrification. This step of nitrogen cycle is not prefered by the farmers as it limits the availability of ammonia and nitrates to the plants.
When you hypothesize you make a possible explanation for a set of observations or you estimate what the answer to a scientific question. Experimenting is when you test your hypothesis to see if it is correct.
Event 5, Event 3, Event 1, Event 2, Event 4 I think!
