Answer:
A. freezing and thawing
B. plant growth
D. abrasion
Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. All of these processes break rocks into smaller pieces without changing the physical composition of the rock.

Skins cell reproduce more because let’s say for example you get hurt and the skin falls off in order to protect you it grows back immediately
Answer:
1. Potassium
2. increasing towards zero
3. hyperpolarization
4. voltage-regulated Potassium
Explanation:
Membrane potential can be defined as the difference in electric charges inside and outside of a cell. The resting membrane potential (RMP) occurs when there is no net current across the membrane and therefore the cell is in a non-excited state. At the RMP, sodium ions (Na+) are more concentrated inside the extracellular fluid (ECF) than inside the intracellular fluid (ICF), while potassium ions (K+) are more concentrated inside the ICF. The diffusion of K+ outside the cell triggers its hyperpolarization, by becoming the membrane potential more negative compared to the resting potential. As the potential nears +35 mV, the voltage-regulated potassium channels are open, thereby K+ ions leave the cell down its concentration gradient, while voltage-gated Na+ channels become saturated and inactivate.

<h3>What is food?</h3>
- Any substance taken as food serves as an organism's source of sustenance.
- Food is often made from plants, animals, or fungi and contains vital elements including carbs, lipids, proteins, vitamins, and minerals.
- The material is consumed by an organism and absorbed by its cells in order to supply energy, support life, or promote growth.
<h3>What purpose does food serve?</h3>
- Something that has nutrients is a food.
- Nutrients are substances that give the body the energy it needs for activity, growth, and all of its bodily activities, including breathing, digesting food, keeping warm, and they also give the body the building blocks it needs for growth and repair as well as for maintaining a strong immune system.
