Microbial mining is when you use microbes to help you obtain specific minerals. Biotechnologists help with this.
What is the connection between a property of life and carbohydrates?
Answer:
The simple carbohydrates include single sugars (monosaccharides) and polymers, oligosaccharides, and polysaccharides. Simplest group of carbohydrates and often called simple sugars since they cannot be further hydrolyzed. Colorless, crystalline solidwhich are soluble in water and insoluble in a non-polar solvent.

The siboglinid tube worm, found at deep-sea hydrothermal vents and cold seeps, has no digestive tract. It relies on symbiotic bacteria that live in the tube worm’s tissues. The bacteria oxidize hydrogen sulfide or methane for the worm.
What type of relationship is this?
Answer:
mutualism
Explanation:
There is a mutual benefit in both parties.
The relationship between the siboglinid tube worm and the symbiotic bacteria that live in its tissues is an example of mutualism, a type of symbiotic relationship in which both organisms benefit from the interaction.
What is a mutualistic relationship?In a mutualistic relationship, both organisms benefit from their interaction with each other. This is different from parasitic or commensal relationships, where one organism benefits at the expense of the other, or where one organism benefits while the other is neither helped nor harmed. In the case of the siboglinid tube worm and the symbiotic bacteria that live in its tissues, the tube worm benefits from the bacteria's ability to oxidize hydrogen sulfide or methane, which provides the worm with a source of energy and nutrients. This is important because the tube worm has no digestive tract of its own and cannot obtain food directly from the environment.
Hence, the relationship between the siboglinid tube worm and the symbiotic bacteria that live in its tissues is an example of mutualism.

The primary function of DNA is to?
Answer:
The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.
Explanation:
A in Biology class last year.
DNA is the genetic material of many organisms. The primary function of DNA is to store the genetic information that results in protein synthesis.
What is DNA?DNA or deoxyribonucleic acid is the nucleic acid that includes the instruction and the information that codes for protein synthesis. It is a crucial part of hereditary that passes the genetic traits from one generation to another.
The major role that it plays in an organism is to store the genetic code and information so that it can be used to synthesize proteins through the process of transcription and translation.
Therefore, DNA stores genetic information.
