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.

A template strand of DNA contains nucleotides in the following proportions: 14% adenine
MAXImum [283]

Answer:

The proportions of  nucleotides in the newly formed complimentary strand will be:

14% Thymine (T), 33% Adenine (A), 21% Guanine (G), 32% Cytosine (C).

Explanation:

In a double stranded DNA, the nucleotides of one strand binds with nucleotides of another strand through hydrogen bonds.

Adenine binds with thymine by two hydrogen bonds (A=T) and guanine binds with cytosine by three hydrogen bonds (G≡C).

So, the complimentary strand must have

  • thymine equal to the amount of adenine in template strand.
  • adenine equal to the amount of thymine in template strand.
  • guanine equal to the amount of cytosine in template strand.
  • cytosine equal to the amount of guanine in template strand.
