<span>Liquid carbon dioxide forms only at pressures above 5.1 atm; the triple point of carbon dioxide is about 518 kPa at 56.6 C. At this temperature and pressure CO2 will exist as a solid, liquid and gas. You cannot get a liquid by cooling alone - you have to increase the pressure as shown.</span>

The phase diagram required to answer this question is missing but I have attached the image to this answer.

The lower triple point is the point of the diagram where all three phases meet, roughly around 4000 K. In order to produce liquid carbon, we must change either the temperature and/or pressure to cause this change in state. If we were to simply raise the temperature, we would move to the right of the triple point which would enter the gaseous phase. If we only changed the pressure, we we would move up from the triple point, which would still be solid phase. Therefore, we must raise BOTH the temperature and the pressure to reach the liquid phase for carbon.

Bezzdna [24]
There is a 3/4 chance their offspring will be black. If you make a Punnett's (I hope that's how you spell it) square then you will find that one offspring will be homozygous for black hair, two will be heterozygous with black hair, and one will be homozygous with brown hair. Therefore, there's a 3/4 chance the offspring will have black hair. Hope this helped!

Virty [35]

Answer:

You could use the fossil record to help explain the evolution of a species by watching how it aged, what it ate, how it breed and where it lived along with a million of other things. It could have lived in the 20 below freezing and then you find that same fossil in the warmest place in the world it shows that the species either adapted or possibly had an offspring that could handle the high temperatures.
