Answer:
Maintaining biodiversity has a direct economic value to humans. Humans depend on<u> plants and animals to provide us with food, clothing, energy, medicine, and shelter.</u>
Explanation:
As many as 40,000 species of plants, animals, and fungi<u> provide us with many varied types of clothing, shelter and other products. These include timber, skins and furs, fibers, fragrances, papers, silks, dyes, poisons, adhesives, rubber, resins, rubber, and more. We use animals for energy and transportation, and biomass for heat and other fuels</u>
1 Nitrogen Fixing.
2 Decomposition and Ammonification.
3 Nitrification.
4 Denitrifying bacteria.
Answer:
true
Explanation:
Molecules are both vehicles for storing and transporting energy, and the means of converting it from one form to another when the formation, breaking, or rearrangement of the chemical bonds within them is accompanied by the uptake or release of heat.
The action potential spreads through an axon by depolarizing adjacent membrane to threshold.
- K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.
- Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.
- Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.
- Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is is greater inside the cell than outside.
