umka21 [38]

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.

Scientists often want to know if the genetically transformed organism can pass its new traits on to its offspring and future gen
Orlov [11]

Answer:

Quickly

Explanation:

The more quickly that a new generation of organisms develops and reproduces the faster that you will be able to observe whether the new traits  have been passed on to the new generation or not, and so on if you want to see this effect over several generations. For example, if you have genetically modified corn, you just have to wait one year to see if next year's generation of corn will have the modified trait or not. Conversely, if you geneticall modify an apple, you have to wait several years until the new generation of apples mature and are able to flower and produce the next generation of apple embryos.
