Clouds help us predict severe storms by their appearance. Their are clouds that signify that a thunderstorm, for example, is going to occur. Look for small patches of alto-cumulus clouds, which signify thunderstorms.
⭐️The answer is ⭐️
As weight = mass × g so we have more weights on earth than on moon. Explanation: This is because gravitational force is immediately proportional to the mass of an object. Greater the mass, greater will be the gravitational force exerted by it and thus, more will be our weight
240mL = 0,24L = 0,24 dm³
----------------------------------------
C = n/V
n = 3,5 M × 0,24dm³
n = 0,84 mol NaOH
1 mole NaOH ---------- 40g
0,84 mol ----------------- X
X = 40×0,84
X = 33,6g NaOH

Answer:
A) Dilute the unknown so that it will have an absorbance within the standard curve. Once the diluted unknown concentration is determined, the full strength concentration can be calculated if the dilution process is recorded. Beer's law only applies to dilute solutions, so diluting the unknown is better than making new standards.
Explanation:
Beer's law states that <em>absorbance is proportional to the concentrations of the absorbing species</em>. This is verified in the case of diluted solutions (0≤0.01 M) of most substances. <u>As a solution gets more concentrated, solute molecules interact between themselves because of their proximity. </u>When a molecule interacts with another, the change in their electric properties (including absorbance) is probable. That's why <u>the plot of absorbance versus concentration stops being a straight line</u>, and <u>Beer's law is no longer valid.</u>
Therefore, if the absorbance value is higher than the highest standard, dilutions should be made. Once this concentration is determined, the full strength concentration can be calculated with the inverse of the dilution.
Everything. DNA contains genes and which genes a person has determines which (if any) proteins are formed. Based on how much of a protein is formed determines how strong a trait is expressed. DNA is the genetic material that contains genes. genes contain information about an organisms trait. hope this helps :)
