Which is NOT true of algae? a) some are prokaryote and some are cukaryotic b) they can be multi-cellular or unicellular s most have cell walls but some like euglena and its relatives do not have cell walls on w e are photosynthetic microorganisms that are important to the ecosystem because they are cycling of the element carbon. 3. Some bacteria have unusual metabolic properties. Some can even degrade (break down) comples toxic compounds like pesticides. This capability is known as: a) bioremediation bybioredaction e ) biodetoxication d ansubstantiation ___16.

Which is FALSE of this type of organic molecule? a) the carbon "backbone" is the molecule glycerol which has three alcohol groups b) attached to the carbon backbone" are two fatty acids that are often-16-20 carbons in length c) because the molecule has a hydrophobic and a hydrophilic portion, phospholipid molecules can arrange themselves to form a bilayer when in water d) attached to one of the carbons in the backbone" is a phosphorus-containing hydrocarbon which contains many non-polar covalent bonds and makes this part of the molecule hydrophobic

Answer 1

11. d . phosphate group.

12 .d both covalent and hydrogen bonds.. hydrogen bond is intermolecular , whereas covalent bond is intramolecular.
