Answer:
The correct answer is option d. "Protein movement is limited by the presence of a diffusion barrier".
Explanation:
There are transportation mechanisms that allow to take up nutrients to the apical surface of the epithelial cells. The transportation process is best describes as protein movement limited by the presence of a diffusion barrier. There are structures known as tight junctions, located just below the apical surface . These tight junctions acts as diffusion barriers, separating the extracellular fluids surrounding the apical and basolateral membranes.
Answer;
Statocysts
Explanation;
-The small organs of equilibrium in scyphozoan jellyfishes are called statocysts, and these are borne in more complex sense organs called rhopalium.
The statocyst is a balance sensory receptor present in some aquatic invertebrates, including molluscs, bivalves, cnidarians,ctenophorans, echinoderms, cephalopods and crustaceans. These structures aid in orientation and balance during swimming in medusae and are located around the margin of the bell in Craspedacusta.
Answer:
B, Different granulation sizes of black powder
Explanation:
A muzzleloader firearm is a firearm that has a muzzle through which the propeller and the projectile is loaded from. For muzzleloader firearms, Fg, FFg, FFFg and FFFFg are examples of Different granulation sizes of black powder. The number of F's represent how the black powder is grounded, FFFFg is the smoothest and is used for muzzleloading rifles of 45 caliber and smaller. FFG is less smooth and is used in muzzleloading rifles larger than 45 caliber while FG is the most coarse used in large bore shotguns.
