<span>Soils rich in organic material are always highly fertile.</span>
Just like in humans, radioactive material can damage plant tissues as well as inhibit growth. mutations are possible due to damage caused to the DNA. radioactive material in soil can prevent nutrient from being taken in by plants, causing it to be infertile.
Answer: 1. The resting membrane potential would become less negative (more positive).
Explanation:
Resting membrane potential is a voltage carried by a resting (non-signaling) neuron, or called as resting potential, across its membrane. The resting potential is determined by ion concentration gradients across the membrane, and the permeability of the membrane to each ion form.
In a resting brain, there are gradients of concentration across the Na+ and K+ membranes. Forces shift their gradients down through channels, resulting in a separation of charges that provides the potential for rest. The membrane is much more permeable to K+ than to Na+, so the resting potential is similar to K+'s potential for equilibrium.
Hence, the correct option is 1. The resting membrane potential would become less negative (more positive).
