Answer:
decreased mass - less energy needed for movement - less carbohydrates required - more available ATP
Explanation:
Solution; Increased muscle mass in athletes will increase the number of mitochondria in body. Mitochondria provides energy to cells of our body so more mitochondria will results in more energy and due to large amount of energy there will be increased cellular respiration and less fatigue, thus athletic performance will be improved.
A molecular clock is a method used by researchers that uses mutation rates in DNA to estimate the length of time that two species have been evolving independently. This provides evidence of evolutionary descent because it can link to common ancestors.
Answer:Sexual reproduction allows them to produce fit offspring that can survive under stressed environmental condition
Explanation:Reproducing sexually and asexually allows fungi to adjust as per the environmental condition.
When the conditions are favorable, they reproduce asexually and increase their number but when the condition are not favorable and environmental selective pressure occur then they undergo genetic variation through sexual reproduction to produce a stable and fit offspring that could survive under stressed condition with limited resources.
