Biology shows us the fossil record and comparative anatomies. Chemistry shows us that organic molecules can come from inorganic matter. Geology shows us that organisms that used to live together are found on separate continents due to continental drift. Which fields of science provide evidence for evolution? a.)biology only b.)biology and chemistry c.)biology and geology d.)biology, chemistry, and geology HEELLLLLP PPPLLLSSS

Answers

The answer to your question is D. To create the full picture of evolution, and how the species that exist on our planet came to exist in their current forms, it is important to take in information from all the possible fields of science including biology, chemistry and geology.

Biology, chemistry, and geology is the answer.

A mixture of oxygen, hydrogen, and nitrogen exerts a total pressure of 378 kPa. If the partial pressures of oxygen and hydrogen are 212 kPa and 101 kPa respectively, find the partial pressure exerted by nitrogen.A. 65 kpa
B. 313 kpa
C. 166 kpa
D. 277 kpa

Answers

As we know that

P total = pO +pH +pN

P = P1 + P2 + P3

378 kPa= 212 kPa + 101 kPa + P(H2)

P(H2) = 65 kPa

partial pressure is 65

so correct option is A

hope it helps

Answer:

The correct answer is option A.

Explanation:

Total pressure of mixture = p = 378 kPa

Partial pressure of the oxygen gas = $p^o_(O_2)=212 kPa$

Partial pressure of the hydrogen gas = $p^o_(H_2)=101 kPa$

Partial pressure of the nitrogen gas = $p^o_(N_2)=?$

As we know that total pressure is sum of partial pressures exerted by all the individual gases.

$p=p^o_(O_2)+p^o_(H_2)+p^o_(N_2)$

$378 kpa=212 kPa+101 kPa+p^o_(N_2)$

$p^o_(N_2)=378 kPa - 212 kPa-101 kPa=65 kPa$

65 kPa the partial pressure exerted by nitrogen.
