<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.
I am pretty sure its called the "Biological Soup theory"... I hope I helped!
This is an example of microevolution.
Microevolution represents a small change in the genetic structure of the population. These changes manifest through the change in the allele frequencies of genes like in the case of dung beetles.
The causes of microevolution are evolutionary mechanisms, natural selection, genetic drift, mutations and gene flow.

The geologic time scale is organized based by major geological events.

The answer for that is cell body. It goes in the blank.
