Answer:
Cross bridge in a sarcomere of a fast fiber produce higher amounts of force as compared to a cross bridge in a sarcomere of a slow fiber
Explanation:
When a muscle contracts, a cross bridge is formed between actin and myosin. The sarcomere shortens when a muscle contracts by reforming cross bridge. In general a muscle fiber is of three types – a) slow, b) Fast and c) intermediate.
The sarcomere of fast fiber generates high force but for a short period of time. On the other hand, sarcomere of slow fiber generate lower amounts of force but this force lasts for a longer period of time. Due to this difference, fast fibers are the predominant fibers in the body
The condition is called macrocytic anemia.
The most common causes of macrocytic anemia are vitamin B-12 and folate deficiency.
Without the sun the planet would be extremely could and we'd all die, and plants use the sunlight for photosynthesis.
Explanation:The main functions of polysaccharides in plants are the protection and energy. If you look carefully, plant cell walls are made up of cellulose and hemicellulose. These two are the major plant polysaccharides that provide rigidity and physical strength the cell wall and the whole plant. :)
