never give up its an order if you do then so dose life
Explanation:
never give up
Answer:
This question is incomplete
Explanation:
Experimentally, when trying to determine the concentration of an unknown sample of CuSO₄ with known absorbance, a standard curve is used. The standard curve is a scattered plot/graph in which known concentrations and there respective/corresponding absorbance are plotted on a "X and Y axis" graph (scattered plot). The absorbance is represented on the y-axis while the concentration is represented on the x-axis.
Once this known values are plotted on the standard curve, an unknown value (either absorbance or concentration) can be extrapolated from the curve. What is missing from the question is data required for the standard curve.
This question shows the absorbance of the CuSO₄ has been determined (most likely using spectrophotometer), the concentration could have been extrapolated from a standard curve.
An example of a standard curve is provided in the attachment for guidance.
Answer:
Perfectly in theory, except there is chance involved
Explanation:
The Punnet square is a diagram that allows scientists to predict the possible outcomes of the offspring when the genotypes of the parents are known. This is in line with Mendel's principles, and from a theoretical point of view would match up perfectly. However, it all works based on <em>probability</em>.
However, inheritance is always down to chance. Of your parents 2 alleles, you always have 50:50 chance of inheriting one of the allele. Overall, this is what is predicted in punnet squares.
However, think about flipping a coin. There is always 50:50 chance of getting heads, but that doesn't mean it is impossible to flip a coin and get tails 10 x in a row. It is just less likely. So in reality, observations might deviate from the theory.
Answer:
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes

<span>Human sweat is a result of our body getting over heated. We sweat through our pores so our temperatures don't go up and as a result we stay at a normal temperature. We may feel hot but that's because we are hot from the heat of something. If we didn't sweat then our temperature would become very high and we would die.</span>
