During the exercise period (10-15min) the blood lactic acid concentration increases to about 13.2 mmol/dL (same units as on graph) as the individual is having problems keeping up their aerobic respiration. After 15min, they stop exercising and the lactic acid concentration starts to return to normal as their body is able to take in enough oxygen and catches up with the excess lactic acid, metabolizing it into CO2 and H2O. The period between 15-20 min shows the fastest reduction in concentration.
Answer:
water because it has webbed feet
Explanation:
Answer: independent variable- strawberries that got water
dependent variable- water
control- strawberry that didn’t get any water
Explanation:
Answer:
The correct answer is - O and 6.9; 7.1 and 14
Explanation:
A measuring scale that tells about the acidity or basicity or alkaline nature of a particular object or solution is possible with the help of a pH scale that measures how acidic or basic a solution or object is.
It ranges between 0 to 14. pH less than 7 or ranging from 0.0 to 6.9 is acidic and more than 7 or from 7.1 to 14.0 is basic or alkaline in nature. A measure of the relative amount of H+ ion and OH- ions in water is pH.
Answer:
arrow (which creates the resultant vector)
Explanation:
When you use the graphing technique when adding vectors, you can use the head to tail method to draw the vectors. And from the starting point or the tail of the first vector you drew, you will draw an arrow touching heads with the head of the last vector drawn.
With that, you can use a ruler to measure the resultant vector's magnitude, and use a protractor to measure it's direction.
Below is an example:
Let:
V1 = Vector 1
V2 = Vector 2
R - resultant vector.
