To make the quadriceps perform more work and increase the efficiency of the exercise, Sean should minimize the amount of trunk flexion at the start of the concentric phase.
We can describe trunk flexion as forward pelvic tilt and flexion of the spine. This activity causes more pressure on the muscles of your quadriceps and hence helps in building them.
The quadriceps can be described as the muscles that are present in the front region of the thigh. These area has more muscle mass as compared to other areas of your brain and hence need to be worked on so that the muscle mass here can be reduced.

Answer:
environmental stochasticity, and demographic stochasticity.
Explanation:
The small population species are prone to extinction. Due to the process of evolution, many species raised from a single species. This is because of variation, different individuals came and survive. But all the species can't achieve reproductive success. They also can't adapt to the changing environment. The changing of the environment in the biodiversity is called stochasticity. The fewer Populus species can't face the natural selection. As a result, their mortality rate is more and the natality rate is high. Sometimes demographic stochasticity also responsible. The fewer reproduction results in less number of the individual over time. This causes mass extinction. The extinction of dinosaurs is an example of mass extinction. The more reproduction of the species means more variety. They can better adapt to the changing environment. Some of the extinct animals are also living and known as living fossils. e.g. Armadillo, Platypus. The changing biodiversity and randomness of the population cause the extinction of a small population.
Answer: nervous and endocrine system.
Central nervous system(CNS) is needed to send a signal to many organs to work. Damage in CNS can cause you to stop breathing. The endocrine system is keeping the body healthy by make sure that the blood concentration of glucose and other molecule is enough to sustain life, but not too much to cause damage.
I know this sounds silly but I just took the test they were made in the stars or B
