Answer: D. the hardening of liquid magma that leads to igneous rock
Explanation:
1) 1 second = 1000000 microseconds
2) 186000 / 1.61 = 115527.9503 Km
3) We use the equation:
Speed = distance / time
4) rearrange for distance by multiplying both sides by time to get;
Distance = speed x time
5) plug in the values:
Distance = 115527.9503 x 0.000001
= 0.1155279503 Km
Answer:
Mitochondria - energy production in plant and animal tissue
Explanation:
The mitochondria is the power house of a cell. it contains adenosine-tri- phosphate or ATP molecules that produce energy through active transport. The mitochondria is responsible for energy production in both plant and animal cells
Answer : The fraction of the molecules in the neutral (imidazole) form are, 0.799
Explanation : Given,
pH = 6.6
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
...........(1)
Now we have to determine the fraction of the molecules are in the neutral (imidazole) form.
Fraction of neutral imidazole =
Now put the expression 1 in this expression, we get:
Fraction of neutral imidazole =
Fraction of neutral imidazole =
Fraction of neutral imidazole =
Fraction of neutral imidazole = 0.799
Thus, the fraction of the molecules in the neutral (imidazole) form are, 0.799
