What were the independent, dependent, and control variables in your investigation? Describe the variables for each part of the experiment.
Dependent variables are those that need a stimulus to present themselves. The independent variables are those that do not need a stimulus to present themselves and the control variables are the elements that remain unchanged throughout the experiment.
Importance of variablesThey present the relationship between the elements of the experiment.Allow hypotheses to be tested.Allows comparisons between experimental treatments.They encourage the evaluation of experimental data.To increase the understanding of these variables, we can use as an example an experiment that seeks to evaluate the influence of root growth of transgenic corn with water stress. In this experiment, five plants of transgenic corn will suffer different levels of water stress, while one plant of the same corn will not suffer this stress and will be watered normally.
According to this, root growth is a variable that needs a stimulus to present itself, so this is the dependent variable. Water stress does not need any stimulus, being the independent variable. Finally, the corn plant that will not suffer any type of stress will remain unchanged throughout the experiment, being the control variable.

1. The maximum recommended amount of citric acid (H3C6H5O7; the 3 hydrogens listed first are the acidic hydrogens – the only hydrogens that react in a neutralization reaction) in skin creams, serums, and lotions is 0. 50% by mass. A face serum containing citric acid is sold in a 250. 0 mL bottle. If the face serum has a density of 0. 979 g/mL, how many grams of citric acid is in the bottle of serum?.
The density has been given as the mass of the substance per volume of the solution. The mass of citric acid in the bottle has been 1.22 grams.
What is percent mass?Percent mass can be given as the mass of substance in the total mass of the solution.
The volume of the face serum has been 250 mL, and the density is 0.979 g/mL.
The mass of face serum in the bottle has been:
[tex]\rm Density=\dfrac{Mass}{Volume}\\ 0.979\;g/mL=\dfrac{Mass}{250\;mL}\\ Mass=244.75\;g[/tex]
The total mass of face serum has been 244.75 grams.
The percent mass of citric acid in face serum is 0.5%. This states the presence of 0.5-gram citric acids in 100 grams sample.
The mass of citric acid in the face serum sample is given as:
[tex]\rm 100\;gram\;sample=0.5\;g\;H_3C_6H_5O_7\\\\244.75\;grams\;sample=\dfrac{0.5}{100}\;\times\;244.75\;grams\; H_3C_6H_5O_7\\\\244.75\;grams\;sample=1.22\;grams\;H_3C_6H_5O_7[/tex]
The mass of citric acid present in 250 mL serum sample has been 1.22 grams.

If a sound is loud and low-pitched, the sound wave also has which of the following properties?
a: low frequency and high amplitude
b: low frequency and low amplitude
c: high frequency and high amplitude
d: high frequency and low amplitude
[tex] \huge \qquad \underline{ \boxed{ \sf Answer}}[/tex]
Here's the Explanation ~
Loudness depends on Amplitude,
Increase in Amplitude = Increase in loudnessPitch depends on frequency,
Increase in frequency = Increase in pitchTherefore, the correct choice is :
A. low frequency and high amplitude
Fun fact ( added by me )
Generally guys have low pitched voice, so it's actually easy to understand what they say even if they speak fast, but in case of girls there's a shrill type of voice with High pitch ( frequency ) such that sometimes it's hard to understand what they are saying if they are fast, also it's kind of irritating.

Assuming silk from spiderwebs could be made just as strong as Kevlar, why would a company still choose to use Kevlar in producing bulletproof fabrics? (1 point)
A.Spiderweb silk likely involves more chemicals.
B.The cost might be higher for producing spiderweb silk.
C.A much larger amount of silk might be needed to produce the same effect.
D.Spiderweb silk would likely be rejected by the body.
Answer:
C. A much larger amount of silk might be needed to produce the same effect
Explanation:
As you may know it will take a lot of silk to make bullet proof fabric out of it.
Answer:
I Guess C
Explanation:
The availability of spider silk is not enough for what is needed, so i believe C is the right answer. But that means that B is also a bit correct .
How many moles of carbon dioxide are in 3. 33 x
1024 molecules of carbon dioxide?
Answer:
1 mole of CO2 has 6.02 x 10^23 molecules of CO2. Say x moles of CO2 has 3.0x10^23 molecules of CO2. Therefore x = 3/6.02 = 0.50. M = 0.50 * (12 + 2x16) = 0.50 * 44 = 22g.

Question 17 An iron nail is kept in each of the following liquids. In which case would it lose its shine and appear dull? (a) Mustard oil (b) Soft drink (c) Coconut oil (d) Kerosene
Answer:
(b) Soft drink
Explanation:
Because soft drinks contain carbonic acid, which reacts with the iron nail. An iron nail kept in a soft drink will lose its shine and appear dull. Because mustard oil, coconut oil, and kerosene have no reaction with iron nails, they do not lose their shine when maintained in these solutions.
