Answer: a. begins to accumulate significantly at a point that is about 55-65% of Vo2 max
Explanation:
Lactate is produced in the body after the burning of glucose (glycolysis), to supply energy without the presence of oxygen (lactic anaerobic metabolism). In long-term physical activities, oxygen supply is not always sufficient. The organism seeks this energy in alternative sources, producing lactate. For the average human, blood lactate begins to accumulate significantly at a point that is about 55-65% of Vo2 max. The accumulation of this substance in the muscles can generate a hyperacidity, which causes pain and discomfort soon after exercise. Thus, the determination of lactate blood concentration allows indirect evaluation of the metabolic acidosis of the exercise, being one of the diagnostic tools used by Exercise Physiology.
As a mollusc, the animal probably has a mantle and a radula.
Molluscs are aquatic species that belong to the phylum of Mollusca. Mollusca is one of the biggest and most diverse phyla of the sea.
A mantle is a term that describes the fold in their body which secretes the hard protective shell of their body. A radula is a toothed structure (similar to the tongue) used to collect food.
