In hot weather, the testes are protected from the heat by relaxation of the dartos muscle. relaxation of the dartos muscle, cont
liubo4ka [24]

Answer:

Relaxation of the dartos muscle.

Explanation:

Testes are present in scrotum outside the pelvic cavity to maintain the temperature about 2-3 degrees Celsius below the body temperature as required for sperm production. Dartos muscle is the layer of smooth muscle located in the superficial fascia. The contraction of dartos muscle serves to make the skin of the scrotum wrinkled and tight.

During hot weather, the dartos muscle relaxes and makes the surface of scrotum less wrinkled to increase the loss of the heat from its surface. The increased heat loss from the surface of scrotum due to relaxed dartos muscles keeps the testes protected from heat.

Secondary structure is determined by interactions between amino acid side chains and tertiary structure is determined by interac
STatiana [176]

Answer:

False

Explanation:

The sequence of amino acids in a protein is determined by the DNA and the structure of protein thus formed is a linear sequence.  These linear structures undergo structural changes due to the formation of bonds between the constituent molecules.  

When bonds are formed by the interactions between the CO group of one chain and the -H group which forms the backbone is known as the secondary structures. Two types of arrangements arise of this that is the helical and pleated sheet.

When the bonds are formed between the side groups or the R group of the amino acid therefore the amino acid structure formed is known as the tertiary structure.

Thus, false is the correct answer.
