(a current in a fluid that results from convection.)

Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth’s ocean currents, atmospheric weather and geology. Convection is different from conduction, which is a transfer of heat between substances in direct contact with each other.

Explain why excess nitrogen in the water can lead to fewer fish and shrimp
Kaylis [27]

Answer:

Excess nitrogen can cause over-stimulation of growth of aquatic plants and algae. Excessive growth of these organisms, in turn, can clog water intakes, use up dissolved oxygen as they decompose, and block light to deeper waters. So few organisms live in these conditions or even can suffocate and die.

A client performs two repetitions of a bench press exercise with 130 lb and gradually decreases the resistance with each set unt
blagie [28]

Answer:

The correct answer is c. The client is using a Pyramid system.

Explanation:

The pyramidal method owes its name due to its structure: it is based on the gradual increase and decrease of the weight that we must ballast (if we require it in an exercise with ballast) or if we prefer it without additional weight, a gradual increase or decrease of the repetitions . All this increase and decrease in repetitions and / or weight, occurs in a staggered manner between each series for a single exercise, with the aim of being able to recruit a very high number of muscle fibers. It is usually done ascending or descending.

The descending pyramidal method consists of lowering the load, but increasing the repetitions, that is, it begins by applying large loads from the beginning and few repetitions, until ascending in the pyramid and completing the exercise having increased the repetitions and reducing the weight used. With this type, what we achieve is called the strength-resistance of the muscles.
