Out of the following given choices;
a. they increase the amount of energy transferred from the
lungs to the blood
b. they increase the flexibility of the lungs as they expand
during inhalation
c. they increase the volume of the lungs, allowing more
oxygen to be inhaled
d. they increase the surface area of the lungs, allowing the
efficient gas exchange
The answer is D. Due to their microscopic nature, they are numerous in the lungs and are also circular-shaped so as to increase the surface area for gaseous exchange.
Other characteristics of alveoli that increase gas exchange are that they thinned-walled (with only a layer of cells) and moist.
D. metamorphic -> melting -> igneous -> erosion
Explanation:
The sequence that would be the best possible for a rock going through the rock cycle is metamorphic rocks melting to produce igneous rocks that are eroded.
- The rock cycle shows the pathway by which different rock types are formed.
- The origin of the formation of rocks starts with the production of magma.
- Igneous rocks are formed from cooling and solidification of molten magma.
- Metamorphic rocks are formed from the subjection of igneous and sedimentary rocks to high temperature and pressure.
- Sedimentary rocks are formed from weathering, erosion, transportation and deposition of rocks.
- Option D shows a metamorphic rock melting to give igneous rocks and the igneous rock is eventually eroded to form sedimentary rocks.

Last night Jasmine and Jay amount combined is $150+$130=$280
amount donated to charity is 1/4 of $280= $70
amount spent at an amusement park is` 40/100 x $210= $84
the remaining money = 280- (70+84)= $126
35% of their original amount is 35/100x$280=$98
so Jay's claim is not correct because the remaining money is $126 and not $98 as she Jay claims.
