Answer:
b. muscle fascicle
c. muscle fiber
d. myofibril and. sarcomere
Explanation:
When muscle contracts, the myosin and actin filaments slide antiparallel to one another hence shortening the distance between the adjacent Z-lines of a sarcomere (a functional unit of striated muscle). Technically, nonetheless, the filaments do not shorten. A chain of sarcomeres make up a myofibril. Myofibrils bound together in bundles around a sarcolemma make up a muscle fiber. Several muscle fibers bundled together in an endomysium make up a fascicle. Several fascicles bound together in a perimysium make up a muscle. A muscle has blood vessels and innervated nerves that serve the cells and are bound overall by an epimysium.
The blood vessels and nerves in the muscle do not contract.

When the Moon changes from new Moon to full Moon, the lighted side is shown more and more, increasing from the right side to the left until you can see the whole lighted side. This would mean you would see an increasing amount of the lighted side of the Moon.
The statement is true. Dead zones are the zones of oxygen depletion, which is caused by excessive running off of the fertilizers into the water body. These chemicals, particularly the nitrates, which are used by algae etc. which bloom by using the nitrates and use the oxygen present in the water. When they die, oxygen levels become critically low till then, for other aquatic animals like fishes etc., to survive.
Answer:
1) Worldwide 70% of freshwater is used for agriculture.
2) Water scarcity is the lack of sufficient available water resources to meet the demands of water usage within the region.
3) Water scarcity can be fixed by developing water filtration systems, promoting water stewardship, protecting wetlands, improving irrigation efficiency, and increasing water storage in reservoirs.
4) bottled water is meant 100% for human consumption, this is one of the most important and efficient uses of water considering tap water is only used for human consumption 2% of the time due to the waters sanitation
