Atria is a large part of the heart so too big for cells; arteries & veins lead away or to the heart.
Capillaries are the smallest vascular structures that allow materials to be exchanged easily between cells.
Answer:
Elastomeric
Explanation:
An elastomer is a polymer whose main characteristic is elasticity and can even recover its shape after being deformed
The chemical composition of an elastomer is the grouping of thousands of molecules called monomers, which join together forming huge chains. These large chains of polymers are those that give elasticity since they are flexible and are intertwined in a very messy way.
When an elastomer is stretched, its molecules align, allowing many times to take a crystalline appearance. However, upon releasing the tension, it immediately returns to its original state of elastic disorder. The above distinguishes elastomers from plastic polymers.
Some advances is that organelles, cells, and the difference between the cells of a plant and a cell of an animal. This was an advance because not only did we discover new things but we learned how or body functions with them and how they work. Hopefully you got what you were looking for. :)
Enzymes are classified and named according to the<u> types of reactions they catalyze.</u>
Explanation:
According to the International Union of Biochemistry and Molecular Biology nomenclature of enzyme classification, enzymes are classified depending upon the reactions they catalyze and how the reaction transforms the substrate and forms new products.
Based on the reactions:
Addition reaction (removal of a water molecule): hydrases or hydrolases like esterases, nucleases etc
Electron transfer reaction: Oxidases and dehydrogenases
Radical transfer reaction: Transglycosidases, transaminases, etc
Splitting or C-C bond formation: Desmolases
Structural or geometrical change: Isomerases
Hydrolysis of phosphate bonds to join molecules: Ligases
Based on the general principle of recommendations, enzymes are suffixed with –ase depending upon the catalytic reaction and substrate.
Hi!
I would say C, weak, dead, or partial antigens because do you need to be introduced to the disease for your body to fight it.
Hope this helps!
