Answer:
The correct answer is - D) 1000x.
Explanation:
pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the
H+ concentration in acidity/basicity. The more H
+ ions found in solution, the more acidic the substance is as acids donate H
+ ions.
You can calculate the concentration of H
+ from the pH and the equation

So for a pH of 8, we get [

For a pH of 5, we get [

In smoggy areas dark moths have the most higher survival rate than white moths in this question so its going to be (A)
Answer: 5. Simple sugars are carbs with one (monosaccharide) or two (disaccharide) sugar molecules. Many healthy foods like fruit and vegetables naturally contain sugar and shouldn't be avoided as they benefit your health. 6. It's a Gas-Carbon Dioxide and Oxygen. When the cells of your body burn fuel (sugar), they produce a gas-carbon dioxide. When the cells of a green plant make sugar, they need a gas-carbon dioxide.When the cells of your body burn fuel (sugar), they produce a gas-carbon dioxide. When the cells of a green plant make sugar, they need a gas-carbon dioxide. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose. Photosynthetic cells are quite diverse and include cells found in green plants, phytoplankton, and cyanobacteria. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen.
