The right answer is Its striations allow for big movements.
*Skeletal muscle is by definition the muscle that, through the tendon, attaches to the skeleton and allows the movement of the skeleton in a well-defined direction thanks to its essential function of contraction. It has been described, with the first optical microscope observations on tissue in longitudinal section, as a tissue having both transverse and longitudinal striations. Muscle fibers are plurinucleate cells of polygonal shape whose nuclei are located at the periphery of the fiber, attached to the sarcoplasmic membrane. A skeletal muscle fiber is a true syncitium, ie a set of protoplasm fused together. The striated skeletal muscle fiber therefore has the functional characteristics of a giant cell (1-5 cm long, 10-100 μm in diameter).
*Skeletal muscle is a voluntary contraction muscle. Each of the fibers constituting it is a structural syncytium. The intensity of muscle contraction as a whole is a function of the number of motor units that have been activated.
The answer is B. 25°C.
A temperature of 25°C can be considered as a room temperature. It is an optimal temperature for the most living beings which cell potential is considered as standard. It is known that at 100°C water boils, so this temperature cannot be standard, cells will degrade at this temperature. Similarly 0°C and –273°C are too cold, water of the cells will freeze, cells will freeze, and cell potential will not be optimal.
Answer:
4) d
Explanation:
In the given figure, <u>A is a wavelength</u> which is the distance between two crests of a wave. <u>B is a crest</u> which is the highest point located on a wave at maximum distance upward from the middle of the wave. C is a trough which is an opposite of crest meaning that it is the lowest point on a wave from the middle.
Lastly, <u>equilibrium</u> is a point located in the middle of wave. In other words, it is the average of crests and troughs located on a wavelength.
