Answer: Carbon Dioxide, Nitrogen, Argon, and oxygen.
Explanation: Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements.
D - spine alignment and foot size.
Late australopiths had an S-shaped spine that allowed for balance when standing. Shorter and less flexible toes made pushing off the ground much easier.
The probable genotype of the IV-3 with the perspective of autosomal inheritance will be A because he does not have condition A. Therefore both parents must be in condition A.
The probable genotype of IV-3 with the perspective of set=linked inheritance will be BbY this is because he has B condition. Therefore the mothers' genotype must be XBXb and the father's genotype must be XBY.
The probability of IV-4 having condition A is 1/36
The tributaries carry small amounts of salt into the lake
<u>Explanation</u>:
The Greatest salt lake is one of the most saline inland water body in the world.The water carried to this lake by the tributaries is very less as compared to the amount of the salt present in the lake. Rest part of the salt remains in the lake as such.
When the water from the lake gets evaporated, it leaves behind the salt. When time passes by, or years of inflow and evaporation salts they gets deposited layer over layer. The amount of salt added leads to formation of new minerals on the sea floor.
