Yes, there is a relationship between heart rate and blood flow.
<u>Explanation:</u>

Even though the heart is beating more times in a minute, healthy blood vessels get larger amount of blood to flow in an easier way when heart beat gets faster.
In reproductive cells so the answer is A and B
Papillae is the answer I got
Microtubules are one of the cytoskeletal filament systems in eukaryotic cells. The microtubule cytoskeleton is involved in the transport of material within cells, carried out by motor proteins that move on the surface of the microtubule.
Hope this helps you!
An increase in body temperature has been known since ancient times to be associated with infection and inflammation and elevated body temperature changes the T-cells' membranes which may help mediate the effects of micro-environmental temperature on cell function
