Why is carbon found in the backbone of most large organic molecules? you may select more than one correct answer. a. carbon makes 4 bonds with other atoms, creating a geometry that allows for large molecules. b. carbon is very electronegative and makes hydrogen bonds with other atoms, creating a geometry that allows for large molecules. c. carbon makes shares 4 pairs of electrons with other atoms, creating a geometry that allows for large molecules. d. carbon forms ionic bonds with other atoms, creating a geometry that allows for large molecules.

Correct answer is A.

we know that carbon have 4 outer shell electrons so it can make 4 bonds and complete its octet and be stable.

Hope it helps. if you need more info ask.

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.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
