Answer: C. sand dunes and loess deposits
Explanation:
Wind erosion is when wind forcefully moves sand particles from one place to another. This can end up forming sand dunes which comes in different shapes.
Also, loess are gotten from silt and clay that are blower by wind and deposited on a large area lawyer of land. Therefore, wind erosion and deposition may form dunes and loess deposits.

Elliptical galaxies. I hope thats correct.
Answer:
The product that must be produced to kill a bacterium —which causes a disease— is an antibiotic, which through biotechnology can investigate the structure of the bacterium and synthesize the chemical formula needed to produce antibiotics in high amounts.
Explanation:
Antibiotics are specific medicines for the treatment of infectious diseases, produced by bacteria. <u>Antibiotics can kill bacteria and prevent their replication</u>.
If a disease is produced by bacteria, the product that is necessary to kill those microbes is an antibiotic, for which biotechnology is useful.
By using biotechnology —a branch of biology that uses technology as a research and development tool— it is possible:
- <em>Know the structure, functions and behavior of pathogenic bacterial strains.
</em>
- <em>Create chemical formulas -antibiotics- that serve to effectively eliminate bacteria, and cure infectious diseases.
</em>
- <em>The synthesis and production of antibiotics on a large scale, allowing their sufficient availability for use.</em>
