Answer:
The correct answers is: I would predict that animals with longer loops of Henle would be able to concentrate their urine more than animals with shorter loops, and thus they would more likely survive in desserts and other dry areas.
Explanation:
The<em> Loop of Henle</em> is a tubule system that connects the proximal convoluted tubule to the distal convoluted tubule in a nephron, the functional and structural unit of the kidney. Its primary job is to establish a concentration gradient in the kidney's medulla by creating a high urea concentration deep in the medulla using a countercurrent multiplier system that uses electrolyte pumps. Through this mechanism, <u><em>water is reabsorbed to concentrate the urine and impede dehydration</em></u>.
The length of the loops of Henle is of great importance for the countercurrent multiplier system - <u>the longer they are, the more concentrated the urine can get</u>. Therefore, animals with longer loops can survive better in habitats where there is not much water around.

The soil, fertilizers, and pesticides eroded by the surrounding waterways are transported via the water to a location different from their former one. These are taken away by the water flow and deposited in the delta area of the river. This delta is a land-form which is formed by the deposition of the similar substances, where the flow of the river is slower.
Hence, the correct answer is 'Option B'.
Answer:
A) True
The polarity of water is what makes it an ideal transport vehicle for nutrients and micronutrients that are water-soluble. Within organisms, water can be used to transport nutrients and even waste from one part of the body to the other. In the case of humans, urine is used to get rid of soluble waste from within the body.
B) True
During the process of photosynthesis, carbon dioxide (CO2) and water (H2O) are taken from the air and soil respectively. Oxygen is able to produce water when it is reduced. Hydrogen during this process is oxidized.
C) False
Ice floats on water. Hence it cannot be denser than water. Rather, water is denser than Ice. Because of the structure of hydrogen bonds, when they are iced, the bonds tend to pull apart, thus making ice expand somewhat. This expansion creates microscopic pockets of air in the molecules thus given them buoyancy.
D) True (X)
E) True (X)
F) True
Heat Capacity refers to the amount of heat a substance like water can absorb before it's temperature rises by 1 degree. This property is important, because, were it not for the high specific heat capacity of water, many people and plants would have boiled over.
G True (X)
Heat of vaporization is the kind and amount of energy required to alter one gram of liquid into a gas at boiling point

Photons of sunlight enter the plant through the leaves and the plant uses this energy in the mesophyll cells (middle cells), more specifically in the chloroplasts, to conduct photosynthesis. The plant transports water and sugars to the plant via the xylem and phloem tubes which allows the plant to grow and thrive. Carbon dioxide is a product made by the cell which is used during glycolysis to make glucose, or sugar, which is food for the plant. The plant also produces oxygen during the process of photosynthesis which diffuses out of the plant into the atmosphere. Water is used in the process as a reactant for most of the reactions that take place. It’s there to help reactions go along and have the correct products.
