Recovering Ecosystems Define the Problem: Figure out who has a problem, what it is, and why it needs to be solved.
Define Sub-Problems: Break your main problem down into smaller, easier to solve sub-problems.
Determine the Criteria: Decide what conditions would need to be met for the problem to be considered "solved."
Determine the Constraints: Determine what limitations are in place before any solution is considered.
Prioritize the Criteria and Constraints: Put the criteria and constraints in order from most important to least important.
Generate Solutions: Brainstorm, evaluate and refine your ideas, and choose the best solution from your list of priorities.

answer; ///i believe that the correct answer is (a) specialized cells)

image result for describe the various types of gene mutationsghr.nlm.nih.gov

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.

explanation:

not sure but try c two haploid cells

explanation:

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.
