Most animals obtain their nutrients by the consumption of other organisms. At the cellular level, the biological molecules necessary for animal function are amino acids, lipid molecules, nucleotides, and simple sugars. However, the food consumed consists of protein, fat, and complex carbohydrates.
Answer: 5.44×10226.022140857(74)×1023⋅mol−1.
Explanation: So the answer is approx. 0.10⋅mol
<u>Ans: 0.225 atm</u>
<u></u>
<u>Given:</u>
Initial volume of gas, V1 = 450 ml = 0.450 L
initial pressure, P1 = 1.00 atm
Final volume, V2 = 2.00 L
<u>To determine:</u>
Final pressure, P2
<u>Explanation:</u>
Based on ideal gas equation:
PV = nRT ----(1)
where P = pressure, V = volume, n = # moles, R = gas constant, T = temp
Under constant, T and n, eq(1) can be expressed as:
PV = constant
(or) P1V1 = P2V2
P2 = P1V1/V2 = 1.00 atm * 0.450 L/2.00 L = 0.225 atm
Answer:
The types of cells at work in the human body
Explanation:
Rudolf Virchow was a German physician who is known as the father of modern pathology. He contributed to the development of the cell theory by concluding that all cells come from preexisting cells. This led to the conclusion that diseases occur at the cellular level, which allowed scientists to diagnose diseases more accurately.
Considering that Virchow analyzed human cells, the image that Tumu would be most likely to use in his assignment is the one of the types of cells at work in the human body.
