Sea anemones house algae in their tissues. Sea anemones benefit from the food produced when the algae photosynthesize. Scientists believe the algae utilize carbon dioxide from the anemone for photosynthesis. How would you describe the interaction between a sea anemone and the algae that live inside the sea anemone?

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
