Answer:

A band - light central region of sarcomere.

Explanation:

Sarcomere is the basic structural unit of the skeletal muscles. These sarcomere shows striations ( light and dark bands) when veiw under the microscope.

A band or anisotropic band is the dark region of sarcomere. A band consists of both thick and thin filaments of actin and myosin proteins. The A band has the ability to refract light and appears dark.

Thus, the correct answer is option (D).

Sergio [31]

Answer:

Here are the following options to complete the question

Which of the statements below is the best explanation of why athletes would need to monitor lactate levels?

A. During anaerobic respiration, lactate levels increase when muscles cells need more energy, however muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration.

B. During aerobic respiration, muscles cells produce too much lactate which causes a rise in the pH of the muscle cells, thus athletes must consume increased amounts of sports drinks, high in electrolytes, to buffer the pH.

C. During anaerobic respiration, muscle cells receive too little oxygen and begin to convert lactate to pyruvate (pyruvic acid), thus athletes experience cramping and fatigue

D. During aerobic respiration, muscle cells cannot produce enough lactate to fuel muscle cell contractions and muscles begin to cramp, thus athletic performance suffers.

A is THE CORRECT ANSWER

A. During anaerobic respiration, lactate levels increase when muscles cells need more energy, however muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration.

Explanation:

When the muscle cells undergoes anaerobic respiration, lactate are produced. Too much accumulation of lactate results in muscle fatigue. It is necessary for the athlete to prevent high accumulation by adjusting their exercise level

A student pores 10 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve she the
seraphim [82]

The dependent variable is Salt and Water

Because salt is an ionic compound. Namely hydrophilic compounds, meaning compounds that like water.

<h2>Further explanation </h2>

Water dissolves NaCl by hydrating and stabilizing its ions (Na + and Cl-), weakening the electrostatic interaction between the ions so as to prevent the formation of ionic bonds to form NaCl crystals.

The dissolution process occurs through the replacement of hydrogen bonds between biomolecules with one another by hydrogen bonds between the biomolecules and water so as to prevent electrostatic interactions between biomolecules.
