Answer:
No
Explanation:
No, Ana's prediction of sorting out : mixture 1 'marble salt' with by her fingers, ie handpicking is not right.
Marble & salt particles mixture can't be sorted by handpicking. They can be seperated by the method of sieving rather, as marble particles being bigger stay in the sieve & salt particles being smaller (finer) pass through it.
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.

Answer:
what is this for? A-level..?!
Explanation:
Answer:
1.52atm is the pressure of the gas
Explanation:
To solve this question we must use the general gas law:
PV = nRT
<em>Where P is pressure in atm = Our incognite</em>
<em>V is volume = 50.5L</em>
<em>n are moles of gas = 3.25moles</em>
<em>R is gas constat = 0.082atmL/molK</em>
<em>And T is absolute temperature = 288.6K</em>
To solve pressure:
P = nRT / V
P = 3.25mol*0.082atmL/molK*288.6K / 50.5L
P = 1.52atm is the pressure of the gas
