A student performed an experiment to demonstrate that a plant needs chlorophyll for photosynthesis. He used plants that had gree

n leaves with white areas. After exposing the plants to sunlight, he removed a leaf from each plant and processed the leaves to remove the chlorophyll. He then tested each leaf for the presence of starch. Starch was found in the area of the leaf that was green, and no starch was found in the area of the leaf that was white. He concluded that chlorophyll is necessary for photosynthesis.
Which statement represents an assumption the student had to make in order to draw this conclusion?
(1) Starch is synthesized from the glucose produced in the green areas of the leaf.
(2) Starch is converted to chlorophyll in the green areas of the leaf.
(3) The white areas of the leaf do not have cells.
(4) The green areas of the leaf are heterotrophic.

True or false: Most muscles contain a combination of all three muscle types, slow oxidative, fast oxidative, and fast glycolytic
kkurt [141]

Thanks to what we know about muscles and the fibers they contain, we can confirm that the statement in the question is in fact true.

Muscle is a type of tissue which due to coordinated systems that make up their composition, have the ability to contract. This ability allows for greater efficiency. In humans, the muscle systems are classified into three kinds:

  1. Cardiac muscle
  2. Skeletal muscle
  3. Smooth muscle

Despite the different classifications and functions of each muscle type, each of these muscles contains a combination of three types of muscle fibers, which are the fibers listed in the question:

  1. Slow oxidative
  2. Fast oxidative
  3. Fast glycolytic.
