nexus9112 [7]

Answer:

If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children

Explanation:

Even tho the cause of lung cancer is not very clear, a genetic predisposition is of a great influence, his smoking and therefore causing a lung cancer is not appliable to his children because of no connection, but in the sense of having a mutation which makes you predisposable to the cancer with or without the smoking, can lead to a high risk of gene inheritance and therefore inheriting the mutation with a high risk of getting lung cancer excluding the smoking.

Complete the sentence: Ecosystem distribution
Step2247 [10]

Answer:

<em>Hypotheses may vary. Most students will probably state that ecosystems at </em>

Ecosystem distribution is different at different places. Regions at high elevations might usually have low varieties of plants and animals but it cannot be true for every ecosystem located as higher altitudes.

Some communities might be well adapted to live in the cold and hence progress rapidly.

24. An investigator examines voltages resulting from changes in membrane permeabilities. If the cell membrane suddenly had 100 p
omeli [17]

Answer:

Generally, K+ ions ensures re-polarization of  the membrane potential. It always ensures that the neuron returns its resting  state, protecting the  neurons and ensuring episode of rest before the next action potential.

K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.

Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.

Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.
