Answer:
Consumptive rates are so high because water that is applied to a field is considered lost to the immediate water system. It either gets evaporated, used by the plants, or leaves the field as run-off. In addition, leaks or evaporation cause loss while water is being transported from the source to the field, often over great distances.
Answer:
Although direct calorimetry is considered to be the most precise technique for the measurement of metabolic rate, construction of such a chamber that is large enough for doing exercise physiology research (or any research for that matter) is extremely expensive and not at all mobile.
Explanation:
Direct calorimetry measures the heat production of an individual, in calories, when placed in an insulated chamber where the heat is transferred to surrounding water. This is a very accurate method of measuring energy expenditure.
The transformation of gneiss into mica, quartz, and feldspar crystals is an example of physical weathering and disintegration and is denoted as option E.
<h3>What is Weathering?</h3>
This is a process in which rocks are broken down into smaller particles through series of mechanisms and factors.
Gneiss is referred to a type of metamorphic rock which is subject to physical weathering when subjected to factors such as high pressure etc.
The rock also undergoes disintegration into mica, quartz, and feldspar crystals under different types of conditions which is why option E was chosen as the most appropriate choice.

C. disintegration
D. chemical weathering
E. both A and C
Answer:
The replication rate of DNA is exponential, so multiply the number you started with by 2^4 to get your answer.
If you started with one DNA molecule, then you calculate as follows:
1 x 2^4 = 16 DNA molecules
