Sustainable development is divided into five categories. The social domain comprises cultural ethics, which vary by society and have an impact on long-term development.
<h3>
What is sustainable development?</h3>
sustainable development is defined as the "development that meets current demands without jeopardizing future generations' ability to meet their own needs."
1.Cultural norms that have a direct impact on long-term development called as social norms.
2.Natural resource and manufactured goods production and consumption called as technological norms. All current technology advancements that are employed for sustainable development are included in the technological realm.
3: Sustainable development is supported by federal, state, and local government agencies called as public policy. The federal or state government's assistance in achieving a sustainable development is included in the public policy area.
4: Used to meet sustainability goals across all other domains called as economic norm. The economic domain examines the economic benefit created by long-term development.

Explanation:
Compound microscope
<h3>
Further explanation</h3>
In 1665, Robert Hooke used a compound microscope to observe cells. Hooke observes the cell walls of dead plants (in the form of cork) when they appear under a microscope. He named it the cell because it looked similar to a cellula or small room inhabited by monks.
Development of microscopy:
- 1590: Hans and Zacharias Janssen, as Dutch lens grinders, mounted two lenses in a tube to produce the first compound microscope.
- 1660: Robert Hooke published <em>Micrographia</em>, containing detailed observations of biological materials made with the best compound microscope.
- 1676: Anton van Leeuwenhoek was the first person to observe a live cell under a microscope, i.e., the algae Spirogyra.
- 1931: Ernst Ruska constructed the first electron microscope. With the invention of the electron microscope, many infectious agents smaller than bacteria could be seen.
Until now, we can see how important the use of microscopes, especially in microbiology, that is the study of microorganisms.

Answer:
Cytotoxic T cells
Explanation:
Perforin is the cytosolic protein and upon degranulation forms pores in the target cell. Perforin protein helps in the transport of water and ions.
Perforin is present in the granules of cytotoxic T cells. These cells have the ability to kill virus infected cells and cancer cells. Cytotoxic T cells bind with the class 1 MHC molecules. These cells are also known as CD8+ T cells.
Thus, the correct answer is option (A).
