1) list and describe the four levels of organization from the simplest to the most complex and give an example of each.

Levels of organisation include,

1. Cells. Its function is in the living organisms and has unit structure which is the smallest. It has certain functions in the organisms. Example include, bone cells, nerve cells, and blood cells.

2. Organs. They are formed with certain tissues which works together and performs specific activity, Example include, skin, heart, and brain.

3. Organ systems. It has one or more organs and they work together in order to perform certain functions in the organisms. Example include, nervous system, skeletal system, and circulatory system.

4. Organisms. They can either take in materials and from food there is energy which is released, reproduced, grow to respond to environment and release waste.

Example include, animal, human, bacteria, amoeba, and mushroom.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

an honest friend. a friend who cares about me, and wont use me. a friend that i can trust. not someone who is fake

mark this brainliest lol i need one more.
