Answer:Covalent bonds link carbon atoms together in long chains that form the skeletal framework for organic molecules. These carbon skeletons may vary in: ... Compounds with the same molecular formula but with different structures and hence different properties. Isomers are a source of variation among organic molecules.
Explanation:
1.The process of leaf color change. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.
2.The leaves in hot or dry environments may be adapted to reduce transpiration. For example, their stomata may be open at night and close midday. This is the reverse of what usually happens, and it means that the stomata are closet when the rate of transpiration would be greatest.
Through Polymerization larger molecules are formed.
Hi,
I think that you're missing some options, but here they are (let me know if I'm right!
-A population of wolves was introduced
-The amount of disease in the deer population decreased
-More grass was planted
Now, if the gene diversity decreased, it means that a lot of deer died. This could happen because wolves were introduced -this is the correct answer, and the wolves ate some deer.
