1) Amino acid are to a protein what Triglycerides are to be the carbohydrate .
Nucleotide is one of the structural components, or building blocks, of DNA and RNA
Monosaccharides: class of sugars (e.g. glucose)
Phospholipid:a lipid containing a phosphate group in its molecule
Nucleoside is a nucleobase linked to a sugar, a nucleotide is composed of a nucleoside and one or more phosphate groups.
Triglycerides :type of fat (lipid) found in your blood.
2) internal membranes
Cell walls are present in most prokaryotes (except mycoplasma bacteria), in algae, plants and fungi but rarely in other eukaryotes
In eukaryotes, the cytoplasm is the content within a cell membrane minus the content in the cell nucleus. It is where many metabolic reactions occur . In prokaryotes, cytosol is where most metabolic chemical reactions occur.
Ribosomes : found in both prokaryotes and eukaryotes.
Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures.Eukaryotic cells may contain several other types of organelles such as mitochondria, endoplasmic reticulum, and lysosomes.The total area of a cell's internal membranes .
Eukaryotes and prokaryotes possess a cytoskeleton.
3)characteristics of water: high specific heat
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When the temperature of water decreases, the hydrogen bonds are formed and release a amount of energy. Water has the highest specific heat capacity of any liquid.
water has high water tension .
water freezes at 32 degrees Fahrenheit, 0 degrees Celsius.Scientists have found liquid water as cold as -40 degrees F in clouds and even cooled water down to -42 degrees F in the lab.
5) where are ribosomes found cytoplasm bound to the rough endoplasmic reticulum (ER) {A AND C}
Ribosomes are found 'free' in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER. Ribosomes are the protein builders of the cell .
