⦁ Arrange these statements in the right order to describe process of inhalation. Air is drawn into the lungs
Air pressure in the chest cavity decreases
Lungs expand
The diaphragm contracts and flattens
The muscles between the ribs contract to move the ribs up and out

air is drawn into the lungs

lungs expand

the muscles between the ribs contract to move the ribs up and down

air pressure in the chest cavity decreases

the diaphragm contracts and flattens

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.  

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
