Answer:

Explanation:
1. Distance from epicentre
The average speed of P-waves is about 8 km/s.
(a) Convert minutes to seconds

(b) Calculate the distance

2. Time for S-wave
The average speed for an S-wave is about 3.45 km/s.

Low glycemic index foods are useful before exercise and high glycemic index foods are good after exercise.
The glycemic index of a food is a relative measure of how fast that food is broken down. A low glycemic index means slow break down, and a high glycemic index indicates fast metabolism of the food, with glucose having the highest glycemic index of 100.
Low glycemic index foods before exercise help to provide a steady source of energy during the exercise session, and high glycemic index foods quickly replenish the energy that was lost during exercise.
The offspring is most likely all going to be black because if the black is dominant and the speckled is recessive, the black with cover up the speckled! Hope this helped!
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.
