SVEN [57.7K]3 years ago
8 0
Non polar molecule move across a membrane through simple diffusion, when moving up their concentration gradient. Simple diffusion involves movement of molecules through a membrane without the help of integral membrane protein. These molecules are driven by the force of diffusion. This is different from facilitated diffusion where molecules only move with the aid of integral protein in the membrane.

Tom [10]

Sickle cell disorder is an inherited blood disease featured by defective hemoglobin. The condition affects the hemoglobin, or the red blood cells, and their tendency to conduct oxygen. The normal hemoglobin cells are round, smooth, and flexible, and thus, they can travel via the vessels in the body effortlessly.  

On the other hand, the sickle cell hemoglobin cells are sticky and stiff and form a sickle, C shape, when they lose their oxygen. These cells combine together, and cannot effortlessly move through the blood vessels.

Since each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber
zmey [24]

Answer:

B. Shortens

Explanation:

Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.

To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers
