Answer:
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water known as a shelf sea. Much of these shelves has been exposed during glacial periods and interglacial periods. The shelf surrounding an island is known as an insular shelf.

t
Explanation:
b. It is environmentally damaging.
c. It spreads outside its native range.
d. It spreads within its natural range.
Answer: b. It is environmentally damaging.
An invasive species is a kind of living organism such as amphibian, insect, bacteria, fungus, plant or even the seeds or eggs of the organism that is not native to a region or ecosystem but introduced either accidentally or by the migration of the species in search of food, shelter, habitat and mates. The invasive species has the potential to compete with the native species, can harm the environment, and health of the human or other living species.
The invasive species spread rapidly after starving the population of native species for food, shelter and for other needs. The invasive species can affect the availability of water and can damage the quality of soil nutrients. Once it is introduced into a habitat it changes the environmental condition of that habitat adversely.
It is environmentally damaging
b.more of the available freshwater is stored in glaciers and icecaps
c.governments have banned the use of freshwater in rivers and springs
d.the demand for freshwater has increased due to population growth
Answer:
D
Explanation:
Answer: All of the above
Explanation:
The living component of the ecosystem consists of both living and non living components. The living components of the ecosystem consists of plants and animals.
The non-living components of ecosystem consists rocks, river, soil et cetera. The living components of the ecosystem needs to depend on the non living and living components.
The phosphorous, nitrogen and carbon cycle are important for the living components of the ecosystem.
Answer:
The muscular system
Explanation:
The muscular system is a set of muscles that can be controlled voluntarily by a living organism (skeletal muscles) Its main function is to achieve mobility, an action that takes place when electrical stimuli from the nervous system cause the contraction of muscle fibers . Muscles that contract automatically such as heart muscle or smooth muscles are not usually considered part of the muscular system. The whole skeletal musculature corresponds to approximately 40% of the weight of an adult man. The sum of the muscular system plus the bone system formed by the bones gives rise to the musculoskeletal system.
The muscles of the chest, such as the diaphragm, play a crucial role in breathing by changing the size of the thoracic cavity. This relates to the muscle rules as the diaphragm contracts and relaxes to facilitate inhaling and exhaling.
The muscles of the chest play a key role in breathing by changing the size of the thoracic cavity. This allows for the expansion and contraction of the lungs. One example of a chest muscle is the diaphragm, which is dome-shaped and separates the chest from the abdominal cavity.
The structure and function of the diaphragm relate to the muscle rules because it is a skeletal muscle that contracts and relaxes to facilitate breathing. The diaphragm contracts when you inhale, flattening and enlarging the thoracic cavity, while it relaxes when you exhale, allowing the chest to fall.
