Why is scientific knowledge more reliable than other types of knowledge?
RUDIKE [14]

Answer:

D. Because science only uses facts that are proven 100% true through the use of  variables.

Explanation:

All the knowledge we read is science books are not merely some observed facts but the result of a systematic scientific methodology through which facts are tested. Science only gives us that knowledge as facts which is  proven 100% true through the use of  variables.For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic.

Variables are the things hat he changes like environmental conditions in previous example to see that in changed conditions plant is showing changed behavior. This way a scientist strengthens his results. Therefore, we can say that whatever knowledge we get through science is proven 100% true through the use of  variables.

Hope it helps!

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.
