<span>Let's consider a scenario in which the resting membrane potential changes from −70 mV to +70 mV, but the concentrations of all ions in the intracellular and extracellular fluids are unchanged. Predict how this change in membrane potential affects the movement of Na+. The electrical gradient for Na+ would tend to move Na+ Outside the cell (extracellular) while the chemical gradient for Na+ would tend to move Na+ Inside the cell (intracellular).
The electrical gradient is defined as the + goes to the - and the - goes to the +
Na + has a positive charge, but there's more positive charge inside the cell than outside (due to potassium), therefore, Na+ goes extracellular (out)
The concentration gradient considers that the ion will go from the most concentrated to at least concentrated by passive diffusion so no trans-membrane proteins in the game attention.Na + is very concentrated in extracellular and few intracellular, therefore, it tends to go intracellular (in).</span>
Explanation:
D the substance get downeards
Animals will asphyxiate a condition in which the body and most importantly the brain lacks a supply of oxygen. which is called or known as oxygen deprivation
Answer:
It is quiet simple the only way the offspring of two organism could be effected by any sort of mutation is if the mutation accrued during meiosis.
Answer:
C. Organism living in the fallen trees lose shelter.
Explanation:
talking about the effects of storm winds falling trees, it creates more light to reach shorter plant which will help the plants to do photosynthesis well, which will even facilitate their fast growth; that's positive.
Fallen trees becoming food for decomposers can also be positive cause this will help the soil or earth of that forest have fertility
New Clearing attracting animals such as man can lead to extinction of forest which to conservators they feel like no-no-no-no that's they'd see it as a negative consequence of the wind storm effect, yes this can lead to de-sheltering of organisms inhabiting that niche(trees)
