________ thousands of tiny projections that add even more surface area to villi​

Biology
1 answer:
victus00 [196]2 years ago
6 0

Answer:

Each villus, in turn, has thousands of even smaller projections called microvilli (singular: microvillus).

Explanation:

The villi contain capillaries, which are tiny blood vessels. Nutrients are absorbed into these capillaries across the surfaces of the villi and microvilli. Because there are millions of these tiny projections, they greatly increase the surface area for absorption.

Answer:

Experiment 4. Relaxed, the drug will stop the calcium so that it does not act on the troponin

Experiment 5. Contraction: In order for the muscle to relax, the actin and tropomyosin union must occur.

Experiment 6. Relaxation: the release of the actin-myosin complex occurs with consumption of ATP, thus it slides and generates contraction, by adding a hydrolyzable analog, this reaction is avoided giving rise to a prolonged actin-myosin binding which leads to relaxation while last effect.

Experiment 7. Ca2 + Contraction is very necessary so that during muscle contraction troponin can be extracted.
