The respiratory system is the set of organs, which allows breathing, that is to say, the gaseous exchanges between the body and the environment.
The respiratory system can be easily assimilated to a bunch of grapesThe main stem of this branch of grapes is the trachea. then divides into smaller ducts called bronchi. Next, it branches into even smaller branches called bronchioles.
The grapes themselves are the alveolar sacs that are branched with the bronchioles. (each grape is an alveolar sac, the functional unit of the respiratory system).
Answer:
new technological advances
Explanation:
The carrying capacity indicates the maximum population of a particular species that a given area of habitat can support over a given period without destroying or depleting the resource base.
Carrying capacity can be affected by factors such as technological advances, trade and use of fossil fuels for energy . Changes in technology modify the carrying capacity of a population. An example is the use of irrigation and fertilisation in agriculture or shortening rotations between crops, which increases the number of people who can be fed from the resources of a given population due to increased yield.
Answer:
C. The brain controls the contraction of muscles.
Explanation:
Calcium's positive molecule is important to the transmission of nerve impulses to the muscle fiber via its neurotransmitters triggering release at the junction between the nerves. Inside the muscle, calcium facilitates the interaction between actin and myosin during contraction.
The Metamorphic Rock must undergo a process called Weathering and Erosion. Once it has become sediments it goes under another process called Cementing and Compacting. Now it has become a sedimentary rock.
