Some living things don't breathe like virus they don't go through cellular respiration. (Not B)
There are thousands of living things that are not visible to the naked eye, like water bears. (Not D)
Answer:
T=A
A=T
G=C
A=T
A=T
C=G
Explanation:
Just think of it as the opposite when it comes to A T G C
For example, A=T G = C T=A and C=G

Answer:
B) Air Resistance
Explanation:
A reaction force is the opposite of an action force, so what is opposing gravity? Momentum certainly isn't in this instance of the apple falling. Thermal velocity isn't, and anti gravity is a hypothetical phenomenon.
Answer:
Answer is in the explanation.
Explanation:
Let's make a system of equations.
5x+10y=550
x+y=80
Now let's use elimination
-5x-5y=-400
5x+10y=550
__________
5y=150
y=30
Then subsitute 30 in for y to find x. This will leave you with x=50. You will have 50 $5 bills and 30 $10 bills. You can check by subsituting x for 50 and y for 30 in both equations to show why it is correct. Eliminating makes it easier to solve the system of equations.
