<span>Valence is defined as number of electrons that are present in the outermost orbital. Oxygen is in the 16th column of the periodic table and the total number of valance electrons is determined by units place digit of the column position which is 6 for oxygen. The outermost orbital is the high energy level and there are two in that orbit. So the valance is +2.</span>
Heat increases. Smoke is hot, and as long as you have a cooler air Gulf to the burning substances, then the smoke will rise.<span>

Answer:
Some examples of living things are organisms such as plants, animals, fungi, and bacteria. Organisms interact with the living and nonliving things in their ecosystem to survive. ... These living things interact with the nonliving things around them such as sunlight, temperature, water, and soil
Electrons get “excited” or charged by sunlight, then they move on through the photosystem 2 and 1 along the etc or electron transport chain
A function of the cell structure that it provides support to labeled x .
What is the function of cell?
- They give the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks.
- Additionally, cells have the ability to replicate themselves and contain the body's genetic material.
- Each component of a cell has a different purpose.
What is cell structure and function?
- Cell architecture - Individual parts of the cell structure each have a specific purpose that is necessary to carry out life's processes.
- Cell wall, cell membrane, cytoplasm, nucleus, and cell organelles are some of these elements.
- Continue reading to learn more about the composition and operation of cells.
3 Major Functions of a Cell -
- Energy Generation.- Living cells exist in a perpetually active biological state. .
- Molecular Transport - Each cell is surrounded by a membrane that delineates its boundaries and acts as a gatekeeper, controlling the movement of molecules into and out of the cell.
- Reproduction.
