Hello,

Question:

Over time bacteria get used to anti bacterial medicine. Doing this can add symptoms and take away the easiest process of healing grout the human and destroying the bacteria.

Using complete sentences, explain how this speeds up the process of evolution in bacteria.

Answer:

Well, the reason medicine speeds up the evolution of bacteria because it needs to put the medicine ineffect for the vaccine to work properly. The faster it works the easier and less painful it will be for that person. Thats why when they go to hospitals they try to give treatment as fast and quickly as possible so there is no further damage. The medicine works almost instantly.

Edited Answer:

The reason bacteria can evolve faster because the DNA which is sharing which the evolution happen much faster, mostly because you don't have to rely on mutations.

pochemuha

Answer:

1. Eukaryotic

2. Eukaryota

Explanation:

1. Eukaryotic- The newly found species has a cell wall and contains membrane-bound organelles. The presence of membrane-bound organelles shows that the cell is a Eukaryotic cell.

2. Eukaryota- the species is single-celled with the presence of cell wall without peptidoglycan. This shows that the species could belong to the Eukaryota domain proposed by Carl Woese.

Thus, 1. Eukaryotic and 2. Eukaryota is the correct answer.

since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4

Nutka1998 [239]

We have that for the Question "since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4" it can be said that

Why the Kirby bauer test require that the agar have a ph of 7.4 is because while agents may be in excessive activity, given a scenario that the pH is to exceed 7.4 the results might inverse.

From the question we are told

since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4

Generally

Agar has a ph value that should exist between 7.2 and 7.4 within a room temperature,given it solidifies and this should be when initially prepared

Therefore

Why the Kirby bauer test require that the agar have a ph of 7.4 is because

while agents may be in excessive activity, given a scenario that the pH is to exceed 7.4 the results might inverse.

When acetylcholine binds to receptors at the motor end plate, the end plate membrane becames:__________a. repolarized. b. more p

sladkih [1.3K]

Answer:

d. more permeable to sodium ions.

Explanation:

The binding of Acetylcholine with the receptors at motor end plate facilitate membrane permeability to sodium ions therefore opening of voltage gated channels for sodium ions.

Sodium ions diffused into the synapse of post synaptic neuron at the neuromuscular junction.

If the stimulus is up to threshold levels; more chemical(neurotransmitter) gated sodium channels opens, and sodium ions move into the synapse to depolarize the membrane with reversal of charges to generate action potential.

The continuous binding of Acetycholine , leads to permanent opening of sodium ions,and over excitation from depolarization. Acetycholinesterase enzymes breakdown Acetycholine to choline and Acetyl Co -A. These are recycle back to Acetycholiine
