To test acidity levels of water, scientists test its pH. As acid rain falls, the pH Levels in lakes and streams decreases. Candi

ce is working on a project to determine whether acid rain is lowering the numbers of bass and mayflies in a lake. the pH of a water sample to be 54. She concludes that the lake's pH level is causing a decrease in the numbers of bass mayflies present there. How would you respond to Candice's conclusion, based on the data in the graph?

Can you please put the graph in the question so I can see it?

Acids have a pH level power than 7. Water is usually close to 7 pH, but it is usually diluted because of various factors. I'm assuming you mean the pH of the sample was 5.4? This would make more sense. The acid rain would lower the average pH because the rain has a pH less than 7. The rain's pH will also be less than 5.4 because it would need to average with the waters previous pH to get this number.

This bar chart represents at the pH levels at which certain animals cannot live. The lower pH levels begin to negatively affect some animals. Bass and mayflies cannot live in a condition with a pH level below 5.5. Therefore, a pH level of 5.4 is extremely dangerous for both bass and mayflies. Candice can draw the conclusion, based on the chart, that The lake's pH level of 5.4 will cause a decrease in the amount of bass and mayflies. in her hometown.

Mendel investigates stem length, or height in pea plants what if he had investigated human height instead why would his results
WINSTONCH [101]

Human height is one of the traits that belong to traits that cannot easily be placed in discrete phenotypic classes (there is not only tall and short people, there is continuous variation of height between them). Such traits are usually controlled by more than one gene (polygenic traits).

On the other hand, a Mendelian trait is controlled by a single locus.

Humans can have many different eye colors ranging from blue to brown. Which of the statements could explain this array of differ
fomenos

Answer:

Option (b).

Explanation:

Genes may be defined as the functional segment of DNA that are heritable in nature. Genes are responsible for the genotype and phenotype of the living organisms.

The eye color in case of humans is the example of polygenic inheritance. The eye color is controlled by more than two different genes and not just by the two alleles of a particular gene. The presence of the different alleles in the different individuals determine the eye color.

Thus, the correct answer is option (b).
