Answer:
Image result for Two differences between primary and secondary metabolites
Primary metabolites are not species-specific and thus might be identical in some organisms. Secondary metabolites are species-specific and thus are different in different organisms. Primary metabolites are involved in the growth, development, and reproduction of organisms.Aug 18, 2020
Answer:
Variability was seen as imperfection, so natural selection could only eliminate the inferior and imperfect, not giving rise to new things, new species.

Answer:
These bundles are also called Fascicles
Explanation:
Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. muscle is a form of striated muscle tissue, which is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. A skeletal muscle refers to multiple bundles (fascicles) of cells joined together called muscle fibers.
The bundles of muscle fibers are called fascicles, they are covered by the perimysium. Muscle fibers are covered by the endomysium. Inside each skeletal muscle, muscle fibers are organized into individual bundles, each called a fascicle, by a middle layer of connective tissue called the perimysium.
