I believe it should be the 1st and 5th.
Answer:
A. A biofilm
Explanation:
Biofilms have high bacterial density near to 10000000 CFU/ml bacteria. Due to such high densities, these biofilms becomes resistant to the antibiotics. These biofilms are basically community of microorganisms which stick itself to some kind of surface be it living or non-living. The bacteria’s which get attached to these biofilm and grow in an environment in which they possess both tolerance and resistance towards any bactericidal agent. Due to this functional mechanism of bacterias with in the biofilm, they become resistant to antibiotics.
Answer:
D
Explanation:
the peptides produced by this sequence are turned into proteins
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
Answer:
Climate change may aggravate erosion, decline in organic matter, salinization, soil biodiversity loss, landslides, desertification and flooding. The effect of climate change on soil carbon storage can be related to changing atmospheric CO2 concentrations, increased temperatures and changing precipitation patterns. Extreme precipitation events, fast melting of snow or ice, high river discharges and increased droughts are all climate-related events which influence soil degradation. Deforestation and other human activities (agriculture, skiing) also play a role. Saline soils are expected to increase in coastal areas as a result of salt water intrusion from the seaside because of rising sea levels and (periodically) low river discharges
