Due to osmosis, or the movement of unoccupied water molecules to places where there are fewer of them, water will want to flow into a cell that has lots of ions inside of it. The cell membrane slows the movement of water into or out of the cell, which helps the cell maintain a certain volume.
hope it helps
Answer:

Definition of carrying capacity; the number or quantity of people or things that can be conveyed or held by a vehicle or container.
Abiotic<span> variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight.
</span>so, decaying logs in the woods not be an abiotic factor because t<span>he living things in an ecosystem are called biotic </span>factors. Living things include plants, animals, bacteria, fungi and more. so logs would be biotic
Answer:
Tropomysin, calcium
Explanation:
Tropomysin is a protein that prevents muscle contraction hence acts as a contraction inhibitor. It wraps around the actin blocking the binding sites for myosin on the actin.
Muscle will only contract when they get a rush of calcium ions.
The calcium ions binds to troponin, the troponin changes its shape. The change in shape will remove tropomyosin from the binding sites allowing myosin to bind on the actin leading to muscle contraction.
Answer:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
