Answer:
B.
Explanation:
When we say "biosphere", we're referring to the atmosphere, geosphere, lithosphere and hydrosphere, and everything in them. You've probably heard of these in class as the "pillars of Earth" or the "pillars of our planet". In other words, when we talk about biosphere we're talking about life.
Organic compounds are all of the compounds that contain carbon, C, in them. You might know that CHNOPS* are the "7 molecules of life", and you might have noticed that Carbon stands first in the list, and that's not because it makes up a mnemonic, Carbon is indeed the most important one in many ways.
*Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus and Sulfur.

Answer:
The child with the trait is heterozygous.
Explanation:
It's a little difficult to be sure without wider context. But my interpretation of both the graphic and the wording, is that the circle represents a person who has the trait, but not necessarily someone who expresses the trait. The square, on the other hand, seems to represent a person who does not have the trait at all.
Based on that, the squares would be hom-zygous--they possess two copies of a dominant version of the characteristic. And the circles would be heteroxygous--they possess two different versions, one recessive and one dominant.
Unfortunately, this is actually a poorly constructed question, and if the circles are intended to represent an individual who <em>expresses </em>the recessive trait, then the answer would be that the child is hom-zygous. But based on the exact wording of the question, the correct interpretation of the graphic should be as I've explained above.
Answer:
1.08 g/L is the density of air.
Explanation:
Pressure of the gas = P (atm)
Volume of the gas = V (L)
Moles of gas = n = 
Temperature of the gas = T (K)
where:
D = density of the gas = 
R = universal gas constant
w = Mass of the gas
M =Molar mass of the gas
Given = P = 1.0 atm , T = 54°C = 327.15 K
Average molar mass of the gas = 29 g/mol
Putting all the given values in above equation.
D = 1.08 g/L
1.08 g/L is the density of air.
It should be something along the lines of Newton's Law Of Motion or Newton's Third Law.
