Answer:

pH scale

Explanation:

the pH scale, which measures from 0 to 14, provides an indication of just how acidic or basic a substance is. Most parts of our body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale).

A client is being treated for the ingestion of a neurotoxin that interferes with the depolarization phase of action potentials.
masya89 [10]

Answer:

The inflow of sodium ions.

Explanation:

The generation of the action potential requires the change in the membrane potential of the cell. This membrane potential is maintained due to the unequal distribution of the ions.

The cell potential of the cell is -70mV and maintained due to the presence of potassium ions. The depolarization occurs due to the influx of the sodium ions and results in the change in the membrane potential upto +30mV. The neurotoxin that interferes with depolarization process might affect the sodium ions uptake.

Thus, the answer is inflow of sodium ions.

If a natural disaster caused all warbles to go extinct, why would the natural disaster not kill all living organisms?
likoan [24]

Answer:

Living organisms that are able to adapt to the environment (natural disaster) will increase in number while the ones such as warbles who can't adapt will die and go into extinction.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

Additionally, due to genetic variation within populations, some living organisms have a better chance of possessing good or beneficial traits being passed from the parent organism to her offsprings which enables them to survive a natural disaster.

Hence, if a natural disaster caused all warbles to go extinct, the natural disaster may not kill all living organisms due to natural selection.
