All elements in the same group have the same number of valence electrons and hence similar properties.
Equal amounts of all gases have the same volume at the same conditions.
Yes, all amino acids have the same basic composition, though the r-groups causes the variation. There are 20 different amino acids.
Groups share same valence electron. Their chemical property is also same.
Groups! They all have same number of valence electrons in outer shell, which leads to similar chemical and physical characteristics.

The Set‐Up Conditions are all of the things that will be kept constant that might affect the outcome of the experiment. The Set‐Up Conditions can also be referred to as the constantsor controls because they are all the things that you will keep the same in order to conduct a fair trial in both the control and experimental groups. The Set‐Up Conditions should be in list form.
Keeping all the relevant conditions in an experiment the same except manipulated variable is called
no
They all came at the same time.
All gases have same kinetic energy of molecules at same conditions.

The sole purpose for a control group is so the researcher can compare his/her results with the experimental group in order to prove his/her hypothesis is correct by showing conditions before they have changed any variable. in order to achieve this and make it fair all conditions must be kept the same in order to make a fair comparison.
All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
All elements in the same group have the same number of valence electrons and hence similar properties.
