Answer:

Loop of Henle lenght

Explanation:

Juxtamedullary nephrons have a longer loop of Henle that cortical nephrons and as we know this loop has a great function reabsorving water, the longer it is more water is reabsorved. The descending portion of the loop is permeable to ions but not to water so this portion reaborves a great quantity of water. Then in the ascending loop is the opposite, it is permeable to water but not to ions. The ions reabsorved in the ascending loop (20-25% of the Na+) are responsable of the water reabsorved in the descending loop. The longer the loop is more water and ions are reabsorved.

Stratum corneum: composed of corneocytes without nucleus
Stratum lucidum: this stratum is only in palms and soles, and gives them the thick skin appearance
Stratum granulosum: composed of keratinocytes whose nucleus disappear and left a granulated cytoplasm

Protein found within thick filament

nadezda [96]

Answer:

The correct answer will be myosin.

Explanation:

Myofibril in the muscle consists of thick filaments and thin filaments. The protein present in the thick filament is known as "myosin", a protein which converts the chemical energy of ATP into mechanical energy. It moves on the thin actin filaments and is known as motor protein and helps in the generation of force and movement.

This myosin protein is composed of the heavy chain and many light chains which is divided into globular head, neck and tail region.

Thus, myosin is the correct answer.
