61. A measure of acidity or alkalinity of water soluble substances. A pH value is a number from 1 to 14, with 7 as the middle point. Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
62. The pH scale typically ranges from 1 to 14, with lower numbers representing acids, higher numbers, bases. Neutral liquids like water have a pH of 7.
63. The pH scale ranges from 0 to 14.
64. A major problem with the use of fertilizers occurs when they’re washed off the land by rainwater into rivers and lakes.
If oxygen is available, the products of glycolysis are used in cellular respiration. Glycolysis alone produces a small amount of ATP. But other products of glycolysis are used later in cellular respiration to make lots of ATP. These other products are NADH, which carries energy, and pyruvate.
Answer:
B.monosaccharides; disaccharide
Explanation:
Monosaccharides are the building blocks of morecomplex carbohydrates. They are carbohydrates that cannot be hydrolyzed into simpler carbohydrates. They can be linked together through condensation to form disaccharides and polysaccharides.
Disaccharides are formed by linking two monosaccharide molecules together through the process of condensation. They are more complex than monosaccharides. During their formation, water is released.
I just took it, the answer is C.
Answer:
fluvial wetlands
Explanation:
The earliest megafossils of land plants were thalloid organisms, which dwelt in fluvial wetlands and are found to have covered most of an early Silurian flood plain. They could only survive when the land was waterlogged.
