Extinction of species reduces the number of different species in ecosystems, hence lowering the diversity of living things.
The base pairing rules in any DNA molecule are these:
• Adenine always pairs with Thymine(A-T)
• Cytosine always pairs with Guanine (C-G)
Answer:
100,000
Explanation:
pH of coffee = 5
pH of solution = 10
Concentration of H+ ions between successive pH values are in multiples of 10
Hence, the pH difference :
pH of solution - pH of coffee
(10 - 5) = 5
Hence, difference in H+ ions will be :
10^5 = 10*10*10*10*10 = 100,000 times
Mass transit can help reduce air pollution in urban cities because there are fewer cars on the roads, creating less pollution.
