Evidence for evolution reveals that closely related organisms have many (blank)<br>characteristics.​
Mamont248 [21]

Evidence for evolution reveals that closely related organisms have many similar  physical and genetic characteristics.

Explanation:

Closely related organisms have similar physical features and genetic sequences.

When both the physical and genetic features are similar, these organisms are referred to as homologous structure.They are similar, as their evolutionary path is the same.

Example: bones from the birds and arms of the humans, have evolved more or less similarly so they are homologous structure.

In other cases, the organisms might be closely related, but their genetic structure might have a slight change. Due to this change there might be difference in the physical structure.

Example: the chimpanzee and  human have different physical structure even though their evolution have taken the same path and they are closely related.

Gas Law- please help!!!
jekas [21]

The pressure of the carbon dioxide will be 0.09079 atm.

<h3>What is partial pressure?</h3>

The pressure exerted by the individual gas is known as partial pressure.

The partial pressure is given as

\rm P_{Total} = P_1 + P_2 + ...

In a mixture of carbon dioxide and oxygen, 40.0% of the gas pressure is exerted by oxygen.

If the total pressure is 115 mmHg.

The total pressure in atm will be

P = 115 mmHg

P = 0.15132 atm

We have

\rm P_T \ \  \  = P_{O_2} + P_{CO_2}\\\\0.15132 \ \  = 0.4 \times 0.15132 +P_{CO_2}\\\\ P_{CO_2} = 0.09079\ atm

Then the pressure of the carbon dioxide will be 0.09079 atm.

More about the partial pressure link is given below.

Predict which substance in each pair has the higher surface tension.
natta225 [31]

Answer:

(a) Between methanol (CH₃OH) and glycerol (C₃H₅(OH)₃), the substance with the higher surface tension is glycerol (C₃H₅(OH)₃)

(b) Between tetrabromomethane (CBr₄) and chloroform (CHCl₃), the substance with the higher surface tension is chloroform (CHCl₃)

Explanation:

The surface tension of these substances at 20 °C given in mN/m, is as follows:

The surface tension of Methanol is 22.70

The surface tension of Tetrabromomethane is 26.95

The surface tension of Glycerol is 64.00

The surface tension of Chloroform is 27.50

(a) Between methanol (CH₃OH) and glycerol (C₃H₅(OH)₃), the substance with the higher surface tension is glycerol (C₃H₅(OH)₃)

(b) Between tetrabromomethane (CBr₄) and chloroform (CHCl₃), the substance with the higher surface tension is chloroform (CHCl₃)
