Matter and energy are conserved in nature through their use by biological systems, which is dedicated by the Law of conservation.
<h3>What does matter and energy conservation mean?</h3>
Matter and energy conservation indicate that organisms can not create or destroy these elements in nature.
Matter and energy conservation are fundamental for maintaining the state of equilibrium (homeostasis) of biological systems.
In conclusion, matter and energy are conserved in nature through their use by biological systems, which is dedicated by the Law of conservation.

In a phase diagram, the point at which the solid, liquid, and gas coexist simultaneously is called the TRIPLE POINT. There is a specified pressure and temperature at which the substance can exist in equilibrium with these three phases being present.
Answer:
Because of statements (a), (c) and (d).
Explanation:
Let's evaluate each statement to know why they focus on higher alcohols instead of ethanol:
(a) It is easier to produce higher alcohols in microbes than it is to produce ethanol<u>.</u> This is true<u> since ethanol is the major biofuel in the world because it can be easily produced by fermentation technology developed a long time ago. Recently, higher alcohols are produced from microorganisms that are used as microbial cell factories.</u>
(b) Higher alcohols have a higher hygroscopicity than ethanol. This is false since ethanol is more hygroscopic than higher alcohols.
(c) Higher alcohols have a lower vapor pressure than ethanol. This is true, ethanol has a higher vapor pressure than higher alcohols. The vapor pressure is important since it can affect the proper cold starting of the engine.
(d) Higher alcohols have a higher energy density than ethanol. This is true since the production of higher alcohols as biofuels is more desirable than the ethanol because higher alcohols have a high energy density and other more advantages than the use of ethanol.
Therefore the answer of why did they focus on higher alcohols to add to or substitute gasoline instead of ethanol is because of the statements (a), (c) and (d).
I hope it helps you!
The answers to this problem is C
The answer to this question would be: true
Adiabatic is a process of thermodynamic where the system temperature is increased without taking it from the surrounding. The temperature is increased from the increased pressure by compressing or expanding the air.
