Answer:
a. Cats see low-frequency, low contrast objects better than humans.
Explanation:
Mr. Big is able to see something that Pamela does not see because cats have a wider field view of about 200 degrees while that of humans is about 180 degrees.
Cats eyes have 6-8 times more rod cells, which are more sensitive to low light, than that of humans. Their elliptical eye shape, large tapetum and cornea help to gather light for better vision at night.
Answer:
14.8% of H2O2
Explanation:
Based on the redox reaction of H2O2/MnO4- is:
2MnO4- + 5H2O2 + 6H+ ⇄ 2Mn2+ + 5O2 + 8H2O
<em>2 moles of KMnO4 react with 5 moles of H2O2</em>
<em />
To solve this question we need to find the moles of KMnO4 until reach the endpoint. Using the balanced reaction, we can find the moles of H2O2 that must be converted to grams using its molar mass -Molar mass H2O2: 34.015g/mol-:
<em>Moles KMnO4:</em>
0.0297L * (1.4686eq/L) = 0.04362eq MnO4- * (1mol / 5eq) = 0.008723 moles MnO4-
<em>Moles H2O2:</em>
0.008723 moles MnO4- * (5mol H2O2 / 2mol MnO4-) = 0.02181 moles H2O2
<em>Mass H2O2:</em>
0.02181 moles H2O2 * (34.015g/mol) = 0.7418g H2O2
<em>%:</em>
0.7418g H2O2 / 5.0mL * 100
<h3>14.8% of H2O2</h3>
Biotechnology can be safe, but potential risks exist and the danger is vast but biotechnology could help address many global problems, such as climate change and infectious diseases. It could possibly help in many different science fields too. I don’t think it should be banned because it has such a big importance especially that it implications in health and medicine.
