Viewing a cell's mitochondria
Seeing animal tissue that is visible to the naked eye
Studying the structures of a live paramecium
I think it might be the first one
Answer: Viewing a cell's mitochondria.
A transmission electron microscopy is a microscopic technique in which a beam of electron is transmitted through a specimen to form an image. It magnifies the structure of the specimen with high resolution as compared to light microscopes. It can be used to examine the internal structure of the cell. Transmission electron microscopy can be used to study the organelles in the cells. Hence, it can be used to view a cell's mitochondria.
Answer:
Viewing a cell's mitochondria
Explanation:
Can't be the live specimen one because electron microscopes can't view living things.
It's best for looking at things in detail!

The number of chromosomes in a somatic cell is 52 chromosomes as it undergo mitosis cell division.
A somatic cell is also called as vegetal cell. It can make up an organism’s body.
In a multicellular organism all the cells are somatic cells except gametes, stem cells and germs cells,
These cells are involve in growth and development of an organism, also help in repair and regeneration.
In our body, there are about 220 types of somatic cells.
Many cells are differentiated to perform various specific functions. some examples of somatic cell types are skin cells, nerve cell, muscle cell, blood cell.
Somatic cells have diploid set of chromosome and undergo mitosis and contain the same set of chromosomes. Hence, the somatic cell of an organism has 52 chromosome.
