What is the best explanation for what happens to the food's mass and energy when it is consumed by the pygmy shrew? A. The mass is mostly excreted as waste. The energy is burned up and destroyed by the pygmy shrew's high rate of cellular respiration. B. The mass is all used for creating new mass in growth. The energy is stored, used in cellular respiration, or lost to the environment as heat. C. The mass is used for growth, stored, or excreted as waste. The energy is stored, used in cellular respiration, and lost to the environment as heat. D. The mass is used for growth, stored, or excreted as waste. The energy is burned up and destroyed by the shrew's high rate of cellular respiration. Group of answer choices

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
