Answer:
Polymyxin because, it inserts into the cell membrane and disrupts homeostasis.
Explanation:
Antimicrobial effect reacts with the cell membrane of the gram negative bacteria and causes disruption in their cell membrane by creating pores.
The cell membrane of bacteria release endotoxin for creating defense mechanism.
But the effect of certain antimicrobial peptide disrupt the effect of membrane by releasing electrostatic interaction and creates membrane pores.
The interaction between the microbial peptide and the cell membrane causes disruption of the cell.
Thus polymyxin is used to treat against the gram negative bacteria as they breaks the cell membrane of the bacteria.

Answer:
At the bottom of the sequence
Explanation:
According to the "principle of superposition of strata", the oldest rocks are formed at the bottom of sedimentary rock sequences.
The oldest rock layer would contain the the oldest fossil. Weathering, erosion, transportation and deposition would bring all sediments which includes rock materials and remains of living organisms to the basin where they would be lithified to form sedimentary rocks. This makes the oldest fossil to be at the bottom of the sequence. As time progresses, the fossil sequence would continue to accumulate and young upwards as the strata becomes relatively younger. Also, we know that fossils succeed one another in a definite manner.
This why relative dating of rocks can be possible.
Answer:
The selenium particles when coated on paper towels were extremely effective and continuously inhibited (about a 90% reduction) the growth of gram-positive bacteria including S. aureus and S. epidermidis after 24, 48, or 72 hours.
Answer:
The organism belongs to the Protista kingdom as it is unicellular, has cell walls, and has the ability to produce spores.
