Explanation: Females have XX chromosomes while males have XY
It might calculate the volume, but you need the length as well, depending on the object.
Answer:
The correct answer is " As you increase altitude, Earth's gravity is not acting as greatly as when closer to Earth's surface so the weight of air molecules decrease, which also in turn decreases air pressure."
Explanation:
As altitude increases air becomes rarefied. At higher altitudes there is less Earth's gravity acting on the air molecules than at areas close the earth surface. Air pressure is the weight of air acting per unit surface area. At higher altitudes as the weight of air decreases due to reduced gravitational pull the air pressure also decreases.
They are both important cell signaling molecules and both of them contain phosphate groups.
