Answer:
Different organelles play different roles in the cell — for instance, mitochondria generate energy from food molecules; lysosomes break down and recycle organelles and macromolecules; and the endoplasmic reticulum helps build membranes and transport proteins throughout the cell.

Answer:
a third class lever
Explanation:
The third class or interpower lever is a lever that enables fast and dynamic movements. It places the power between the resistance and the support, so the resistance arm is longer than the power.
It is the most frequent type of lever in the human body and as an example we can put the action of the brachial biceps in the flexion of the elbow, where the biceps is inserted in the forearm between the elbow that is behind and the resistance that would be displaced towards the hand by the weight of the load attached to the weight of the forearm.
A good range of movements is achieved although with less force and is the most frequent type of lever in human movement, although the same joint can form different types of lever depending on the type of movement performed

Answer:
11.16 J
Explanation:
Elastic energy (E) stored in the tendon is given by 1/2ke^2
SPRINTERS
k = 31N/mm = 31N/mm × 1000mm/1m = 31,000N/m
e = 41mm = 41mm × 1m/1000mm = 0.041m
E = 1/2 × 31,000 × 0.041^2 = 26.06J
NON-ATHLETES
k = 31,000N/m
e = 31mm = 31mm × 1m/1000 = 0.031m
E = 1/2 × 31,000 × 0.031^2 = 14.90 J
Difference = 26.06 J - 14.90 J = 11.16 J
