3 0

Well latent fingerprints are made of oil and sweat and generally materials that you can't see very easily, so it should be that.

Hope this helps :D

A sample of gas with a volume of 750 mL exerts a pressure of 98 kPa at 30 °C.What pressure will the sample exert when it is comp

Flura [38]

Answer:

240 kPa

Explanation:

The ideal gas law states:

$pV=nRT$

where

p is the gas pressure

V is the gas volume

n is the number of moles

R is the gas constant

T is the absolute temperature of the gas

For a fixed amount of gas, n and R are constant, so we can rewrite the equation as

$\frac{pV}{T}=const.$

For the gas in the problem, which undergoes a transformation, this can be rewritten as

$\frac{p_1V_1}{T_1}=\frac{p_2V_2}{T_2}$

where we have:

$p_1 = 98 kPa=9.8\cdot 10^4 Pa$ is the initial pressure

$V_1 = 750 mL=0.75 L=0.75\cdot 10^{-3} m^3$ is the initial volume

$T_1 =30^{\circ}C =303 K$ is the initial temperature

$p_2$ is the final pressure

$V_2=250 mL=0.25 L=0.25\cdot 10^{-3} m^3$ is the final volume

$T_2=-25^{\circ}C=248 K$ is the final temperature

Solving the formula for p2, we find the final pressure of the gas:

$p_2 = \frac{p_1 V_1 T_2}{T_1 V_2}=\frac{(9.8\cdot 10^4 Pa)(0.75\cdot 10^{-3}m^3)(248 K)}{(303 K)(0.25\cdot 10^{-3} m^3)}=2.4\cdot 10^5 Pa = 240 kPa$

The discovery of ribozymes provide evidence that life on the early earth may have been based on:_________

REY [17]

The discovery of ribozymes provide evidence that life on the early earth may have been based on RNA world hypothesis.

<h3>Origins of Life and the RNA World</h3>

We must think about how these mechanisms developed during evolution in order to completely comprehend the processes taking place in modern living cells.

The production of genetic information, which today requires incredibly complicated machinery and travels from DNA to protein via an intermediary called RNA, is the most fundamental of all such issues.

<h3>How did this equipment come to be? </h3>

One theory holds that there was an RNA world on Earth before contemporary cells emerged. This is the hypothesis.

RNA was a genetic information repository and a catalyst for chemical reactions in the earliest cells.

Proteins took over as the main catalytic and structural component of cells considerably earlier in the evolutionary process than DNA, which didn’t become the major genetic component until much later. If this hypothesis is correct, the departure from the RNA world was never truly complete.
