Q6: A
Q7:D
Q8:C

Reasoning
Q6: Based on all the other questions talking about common ancestors I deduced that to find a “common” ancestor they need to find things that are the same.

Q7: All arthropod have a exo skeleton for example a lobster or crab. They all have a head, abdomen and thorax for example ants. They all have legs with joints for example a spider.

Q7:So bones are traveled down by ancestors so the types of bones stay the same but natural selection has changed them to better fit their environment.

What structural feature in a molecule is necessary for a gas to absorb ir radiation?.
dybincka [34]

The structural feature in a molecule necessary for a gas to absorb IR radiation is: a net change in dipole moment due to the vibration or rotation of the molecule.

IR radiation is the infrared radiation. In the electromagnetic spectrum, its value ranges from  700 nanometers to 1 millimeter. The waves are longer than that of visible light and shorter than the radio waves. The waves are not visible to the human eye.

Dipole moment is a vector quantity. It is equal to the charge of the molecules multiplied by the distance between the two charges. In a dipole there is a positive charge at one end and a negative at the other. The direction is considered from negative to positive.
