Answer:
Protein.
Explanation:
In the image above, we see a molecule that is made up of several amino acids. The molecule that is made up of amino acids is protein.
Proteins are the most abundant organic macromolecules in cells, fundamental to cell structure and function. They are found in all cell types and viruses.
They are formed by amino acids linked together and joined by peptide bonds, as shown in the image above.
Of extremely high molecular weight, proteins are composed of carbon, hydrogen, nitrogen and oxygen, practically all of them have sulfur. Elements such as iron, zinc and copper may also be present.
All proteins are made up of a set of 20 amino acids, arranged in varying specific sequences.
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.
Light will increase the rate of photosynthesis, should be reflected in the rate of disk rising
- no disks should rise in dark since photosynthesis requires light
