A
Explanation:
The others don't make sense, and are the opposite of what would happen if human population increased.
Answer:
Reflection waves bounce off of a surface while in refraction those waves do not bounce back but pass through the surface.
Explanation:
<span>a galvanic cell,or voltaic cell,named after Luigi Galvani, or Alessandro Vlota respectively, is an electrochemecal cell that derives electrical energy from spontaneous redox reactions taking place within a cell. </span>
The five proteins of the myofilaments are the following:
<span>1.
</span>Myosin, shaped like a golf club, with two
polypeptides intertwined to form a shaftlike tail and a double globular head,
or cross-bridge, projecting from it at an angle.
<span>2. </span>Fibrous actin is like a bead necklace—a string
of subunits called globular (G) actin. Each G actin has an active site that can
bind to the head of a myosin molecule.
<span>3. </span>Tropomyosin. It blocks the active sites of six
or seven G actins and prevents myosin cross-bridges from binding to them when a
muscle fiber is relaxed.
<span>4. </span>Troponin a smaller calcium-binding protein bound
to each tropomyosin molecule.
<span>5. </span>Titin (connectin), run through the core of a
thick filament, emerge from the end of it, and connect it to a structure called
the Z disc.
