Answer: biological adaptation
Explanation:
lungfish's lung is a biological adaptation. A biological adaptation is a physical change in an organism that develops over time. Like all fish, lungfish have organs known as gills to extract oxygen from water. The biological adaptation of the lung allows lungfish to also extract oxygen from the air.

There are three rock types in the rock cycle including: igneous, sedimentary, and metamorphic rock.
<u>Explanation:</u>
Any solid or combination of minerals which naturally occurs is understood as a rock. It is classified by the contained minerals, its chemical composition and the manner it is made.
<u>Igneous Rocks:</u> It is generated by magma or lava being refrigerated and solidified. The magma may be produced from partial melting of established rocks, either in the mantle or crust of a planet. The melting is usually caused by one or more of three methods: temperature rise, pressure decrease, or composition transition.
<u>Sedimentary Rocks:</u> These forms that are developed by aggregation or deposition of tiny particles and eventual cementation of mineral or organic substances on the surface of the Earth's ocean floor or other water bodies. Sedimentation is the general term for mechanisms that cause settlement of such particles.
<u>Metamorphic Rocks:</u> These occur from the alteration of different rock types in a technique called metamorphism, which implies change of shape. The initial rock or protolith is heated where temperatures between 150 to 200 ° C and a pressure level of 100 megapascals (1,000 bar) or more induces significant physical or chemical changes.
B) Cytosine and guanine.
The pairs are A/T and C/G.
According to Clausius-Clayperon equation,
is the vapor pressure at boiling point = 760 torr
is the vapor pressure at T_{2} =638.43 torr
Temperature
Δ
Plugging in the values, we get
ln
Therefore, the boiling point of octane = 389 K - 273 =
