Answer:

Below

Explanation:

"All compounds are substances, but not all substances are compounds."

In simpler terms, let us use an example. Look at the image below.

In a big circle, there are substances. And in the small there are compounds. Since the compounds are inside the big circle, they are compounds, but as you can see, the substances are not inside the compounds so they cannot be considered compounds.

If you think about it, a substance is anything. So would you think a bottle, for instance, is a compound? A compound is a mixture of molecules. And a substance is most likely a combination of atoms, which are elements.

Streptomyces griseus produces the antibiotic Streptomycin, which inhibits protein synthesis by binding to ribosomes and preventi

VLD [36.1K]

Answer:

See the answer below.

Explanation:

Antibiotic-producing bacteria are generally known to have a mechanism that enables them to be resistant to their own antibiotics. The mechanism that enables them to be resistant to their own antibiotic depends largely on the mode of action of the antibiotic substance.

Some of the popular mechanisms used by bacteria to counter their own antibiotic substance include a mutation in the target gene, production of enzymes that inactivate the antibiotic compounds, or efflux of the compounds.

In the case of Streptomyces griseus, the inactivity of streptomycin has been linked with the production of a phosphatase inhibitor that prevents streptomycin from getting access to the target site. Hence, the organism is not harmed by its own antibiotic.

Gnoma [55]

Answer:

I think these will be the fat soluble vitamins .....the A,D,E,K

Explanation:

The liver stores vitamin A, D, E, K and B12. The first four of these are all fat soluble. This means that the bile secreted during digestion is essential for absorbing them so that the body can use them. If bile production is compromised by liver damage, the proper absorption of these vitamins may be affected.
