The answer would be A and E
(I explained on the other one)
I would say that the fishes exhibited the greatest diversity (though the brachiopods also had considerable diversity) and mostly were of the ostracoderms (with a platey or shell-like skin and no jawbone) which exhibited many varieties and also the placoderm which had gills, a jawbone and fins so was developing characteristics of modern fish.
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.
<u>In the case of </u><u><em>Streptomyces griseus</em></u><u>, 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.</u>
Answer:
The answer to your question is:
Explanation:
Two molecules with the chemical formulas C₆H₁₂O₆ and C₆H₁₂O₂ are probably monosaccharides.
Monosaccharides is the basic unit of carbohydrates. All monosaccharides have the formula (CH₂O)
.
Monosaccharides most important are glucose, fructose, etc.
It represents the cycle of life, because a tadpole should turn into a frog.
