Answer:
Diffusive force J = 9590
Explanation:
From the given information:
Concentration gradient C₁ - C₂ = 35 mM = 35 × 10⁻³ M
membrane width Δ x = 1 cm = 10⁻² m
Solubility S = 1
diffusive area A = 10
Temperature T = 1° C = (273 + 1 )K = 274 K
Using the expression:
Diffusive force J = 9590
<h3>
Answer:</h3>
The generation of local currents.
<h3>
Explanation:</h3>
An action potential at the axon hillock generates local currents that depolarize nearby sections of axon to threshold. This change in membrane potential causes voltage-gated Na+ channels to open in the adjacent axon segment. This generates/regenerates the action potential in the adjacent segment, causing the action potential to propagate away from the axon hillock.
The correct answer is (c) They show which part of the brain are involved in specific activities.
The functional magnetic resonance imaging is used to measure the activity of brain by the detecting the change in the blood flow. This is done because the cerebral blood flow is associated with the neuronal activation. The functional area of brain has a higher blood flow that can be observed in functional MRI. The commercial application of functional magnetic resonance imaging is used in lie detectors. This technique is also used in research world and in some clinical trails. Physicians use this technique to see how risky a brain surgery can be. It is also used to learn how a normal, diseased, or injured brain functions.
Answer:
D
Explanation:
D is right because the removal of trees and other types of vegetation reduces available food, shelter, and breeding habitat.
