What is Homeostasis?
Homeostasis is a state in which everything within the cell is in equilibrium and functioning properly. The state of homeostasis keeps the cell constant with what it needs to function.

What is the definition of a tropical ocean?
a large body of water (a major part of the hydrosphere) that is characteristic to or located in the region adjacent to either side of the equator.

Bacteria that can adapt easily to their environment.
Prokaryotic cells

How are called organisms like humans according with te number of cells that contain?
multicelular organisms

What part of the cell works to maintain homeostasis?
The main part of the cell that works to maintain homeostasis is the cell membrane. That's the outer wall between the cell and the outside world. Essentially, it's what protects the cell from outside stimuli that could disrupt a cell's homeostasis.

Where in the periodic table are found semiconducting elements?
The fourth group elements. Especially Silicon with atomic number 14 and Germanium with atomic number 32 are the semi conducting materials.

define tissue, organ and organ system: explain their relation:
Group of similar cells that take part in a particular function (Tissue) Group of tissues that work together (Organ) Group of organs that work together for a similar goal (Organ system)

What are the different ways molecules permeate the cell membrane?
The cell membrane maintains homeostasis through the processes of diffusion, osmosis and filtration, which are passive forms of transport. Passive forms of transport move molecules such as water and substrates across the cell membrane with no energy on the cell's part.

What are gloves used for in science?
gloves protect your hands from harmful chemicals also when disecting you may not want to touch the animal
