____4. Red + Green + Blue
Answer:
» 1. A. Yellow » 2.C. Magenta» 3.D. Cyan » 4.B. WhiteThe element lithium has two common isotopes: Li–6 and Li–7 If the average atomic mass of lithium is 6.94004 u, determine its percent isotopic abundances. Step by step and explain.
First we need to determine the average atomic mass of these isotopes.
The atomic masses of Lithium-6 and Lithium-7 are 6.0151amu and 7.0160amu respectively.
Now that we have that, we need to set up the relative abundance problem.
We can do that using the formula (M1)(x) + (M2)(1-x) = M(E)
Because you asked for details, I'll explain what each variable stands for-
M1 = the mass of one isotope
x = the relative abundance
M2 = the mass of the second isotope
M(E) = the atomic mass of the element from the periodic table
Therefor all we do now is plug in our respective variable.
M1 = 6.0151amu (Lithium-6)
x = unknown relative abundance
M2 = 7.0160amu (Lithium-7)
M(E) = 6.94004amu
Now the formula plugged in will look like this:
6.0151x + 7.0160(1-x) = 6.94004
Now doing some quick math, we can determine that x=0.07589
For the last step we need to find the percent abundance of each element, which is quite simple. We take X and multiply it by 100 to find Lithium-6, so 0.076 x 100 = 7.6%
and since then we use 1 - X, so 1 - 0.076 = 0.924
We take that and also multiply it by 100, so 0.924 x 100 = 92.4%
Conclusion:
The abundance of the Lithium-6 isotope is 7.6%, and the abundance of the Lithium-7 isotope is 92.4%.

One variable not mentioned in the description of the experiment that could affect the results of the investigation is reduced canopy cover. Describe the effect that canopy cover would likely have on the results of the investigation.
The canopy cover can affect the results of an investigation because a higher canopy cover is accompanied by a decrease in the availability of sunlight.
The canopy cover is the proportion of the ground covered by vegetation when it is viewed from vertically above the planted area.
The level of canopy cover affects light availability on the ground and also its microclimate, thereby this feature can also alter any biological experimental procedure by affecting the level and type of biodiversity.
A reduced canopy cover may alter any experimental outcome by increasing the energy/light input in the ground cover stratum, thereby likely affecting biodiversity.

List reasons you would or would not be concerned about eating genetically modified food
Answer:
Reasons I would be concerned about eating GMO foods:
Explanation:
The FDA declaring them to be "substantially equivalent" to non-GMO foods amid controversy that adequate scientific testing had not been done.
Michael Taylor being in the FDA when "substantial equivalence" was declared. Michael Taylor was a Monsanto employee before taking the position at the FDA.
The technology itself of taking a gene from one species and inserting it into another species (horizontal breeding). While that may be perfectly harmless it is new technology that many believe has not been proven to be safe.
Greater amounts of pesticides being used on GMO crops, which means more pesticides may be getting in our foods.
Crops that are engineered to produce an insecticide in the plant itself possibly having harmful health effects on us. There is some evidence that this may be happening.

True/False: In a neuron at rest, the concentration of sodium ions is 14 times higher outside the cell than inside the cell.
Answer:
true
Explanation:
The sodium and chloride ion concentrations are lower inside the cell than outside, and the potassium concentration is greater inside the cell. These concentration differences for sodium and potassium are due to the action of a membrane active transport system which pumps sodium out of the cell and potassium into it.

When is the kinetic energy of a pendulum the least?
Question 5 options:
Half the distance on the path traveling back down.
On the path beginning the upwards swing.
At the bottom of the swing.
At the top of the swing where it briefly stops before changing direction.
Answer:
The answer is D. At the top of the swing where it briefly stops before changing direction.
Explanation:
When the pendulum is either at its far right or left position, the bob is at rest and therefore its kinetic energy is equal to zero- making it the lowest point of kinetic energy during the whole process.
Answer:
The answer is C
Explanation:
because when your on the swing the most kinetic energy is where you start to go to the upwards part right when the drop happens
it allows you to swing up very high making the option C correct
