Answer:
b is probably the answer because endosymbiont theory makes the most sense for building prokaryotic cells to eukaryotic cells.
The given statement is False.
The bacterial cells walls are composed of peptidoglycan, also known as murein. It comprises polysaccharide chains cross-linked by unusual peptides, involving D-amino acids. The bacterial cell walls are distinct from cell walls of fungi and plants that are made up of chitin and cellulose, respectively.
The cell walls in bacteria allow small molecules to pass through them freely, however, do not permit large molecules to pass through them, in this manner, it function as a coarse filter.
The main function of the cells wall is to sustain the shape of the cell and inhibit the cell from bursting due to osmotic pressure. The cell wall allows the components to pass, which are essential for bacterial nutrition.
Answer:
This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.
This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore, humans or sick cells do not have the active site to which the drug binds.
Explanation:
This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.
This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore humans or host cells do not have the active site to which the drug binds.
Erythromycin falls into the macrolide family and is considered a drug that is bacteriostatic at low concentrations and bactericidal at very high concentrations.
The difference between these named terms is that one ends the life of the bacterium (bactericidal) and the other stops the bacterial metabolism preventing its possibility of increasing in number.
Answer:
A). The model does not predict energy flow.
Explanation:
As per the given details, the most probable constraint of using 'numerical computer-built models' would be their 'inability to forecast the energy that is flowing throughout the ecosystem.' However, they assist in offering collected information at the same time yet <u>its failure to predict the actual amount of energy flowing that will lead to a failure to predict if the ecological balance is being maintained or not</u>. As a result, some organisms may be deprived of the appropriate food to ensure their survival and their existence on this planet might be under threat. Thus, this is the limitation of using such-technology based models and hence, <u>option A</u> is the correct answer.
