Although plants account for more than 90 percent of the earth’s two trillion tons of biomass, they represent only some 20 percent of earth’s classified and named organisms. In contrast, while the animals make up only a small fraction of the biomass, they represent more than 60 percent of...
Which statement best describes how the body moves? (a) Skeletal muscles, which are made of fibers, nerves and blood vessels, contract in order to make the body move. (b) Cardiac and smooth muscles are made of muscle fibers, nerves, and cartilage and are r ...
The raw material used to make carbon fiber is called the precursor. 90% of the carbon fibers produced are made from polyacrylonitrile. The remaining 10% is made from rayon or petroleum pitch. All of these materials are organicpolymers. The characterization of organic polymers is formed by a lo...
They are high in oils, dietary fibers, proteins, minerals, and vitamins. Apart from producing oil for human consumption, this type of plants is used in various industries, including soaps, paints, machinery lubricants, fuel, and many more....
In addition, when you want to make a muscle group like the thighs look better, you need to perform multiple sets for that muscle group, preferably in the range of 3-6 sets. For each set, you should perform a repetition range that stimulates the growth of new muscle fibers, which is 10...
Explain how cardiac muscle cells are able to function as a syncytium despite being composed of single-cell, mononucleated muscle fibers. How is the wave of depolarization spread throughout the axon terminal? a. What are the functions of the muscle spindle and the Golgi tendon organs? b....
According to Wise, refurbished products are not classified as new, but they have never been used and still come with a manufacturer’s warranty. “These items often come from returns due to buyer's remorse, providing an opportunity to obtain new, unused devices at a lower cost,” he said....

Artwork: The fibers in HEPA filters (shown here as gray bars) trap dust and dirt particles in three ways. Some particles crash into filter fibers and are absorbed by impact. Some are caught as they flow along in the moving airstream, move too close to a fiber and are trapped by ...
Fiberglass insulation, a man-made mineral fiber constructed from a variety of materials, such as sand and recycled glass fibers, is the most popular form of insulation in the United States -- more than 90 percent of homes in America are lined with the pink stuff [source: Spencer and ...
