El sistema muscular humano presenta tres funciones específicas cuales son
bija089 [108]

Answer:

The muscular system is the set of more than 650 muscles in the body, whose main function is to generate movement, whether voluntary or involuntary.

Explanation:

The functioning of the muscular system can be divided into 3 processes, one voluntary in charge of the skeletal muscles, the other involuntary carried out by the visceral muscles and the last process is the duty of the cardiac muscles and autonomous functioning.

Skeletal muscles allow walking, running, jumping, in short, they empower a multitude of voluntary activities. Except for reflexes, which are the involuntary responses generated as a result of a stimulus. As for involuntary functioning muscles, it can be specified that they perform independently of our will but are supervised and controlled by the nervous system, they are responsible for generating pressure for the transfer of fluids and the transport of substances throughout the organism with the help of peristaltic movements (such as food, during the digestion and excretion process).

The autonomous process takes place in the heart, an organ made of heart muscles. The primary function of this muscle tissue is to contract regularly, millions of times, having to endure fatigue and weariness, or else the heart would stop.

Which statement about fungal cell walls is false? Fungal cell walls are similar in function to the cell walls of many protists,
Lerok [7]

Answer:

Cell walls prevent cells from dying in hypertonic conditions.

Explanation:

The cell wall is a rigid structure, essential for the survival of fungi, and knowledge of its composition may be useful for the development of new antifungal drugs. This wall does not alter the characteristics of the fungus, it stimulates and presses the fungus to flourish.

The fungal cell walls are similar in function to the cell walls of many protists, bacteria and plants. They prevent cells from bursting in hypotonic environments, but are unable to prevent cells from dying in hypertonic conditions. These cell walls also provide the cell with a degree of physical environmental protection and differ in the molecular composition of plant cell walls, as the fungal cell walls are chitin, while the plant cell walls are formed by cellulose.
