Answer:
Growing new trees to replace old trees
Explanation:
Growing new trees in place of old ones sustains the environment, since trees help circulate oxygen and provide homes and nutrients for animals and other plants.
Any form of mining is bad for the environment and unsustainable in the long run, garbage is the same way, and putting it on land is only slightly better, and switching to other resources doesn't do anything but burn out more resources and does nothing to sustain anything.
Hope this helps :)
the answer is false, though we adapt in our lives, we simple cannot just add or delete traits the help us survive.

Answer:
A and F are phosphate groups.
B and E are sugars.
C and D are nitrogenous bases.
Explanation:
Nucleotides are the molecules responsible for composing DNA and RNA. They are formed by three units: a phosphate group, a sugar molecule and a nitrogenous base.
The sugar molecule is a pentose, which means that it is a molecule formed by 5 carbons. These collections are represented by geometrical figures such as the letters "B" and "E" shown in the figure above, where each tip represents a carbon.
The nitrogenous bases are molecules that are named adenine (A) and guanine (G) and the pyrimidine bases cytosine (C), uracil (U) and thymine (T).
The phosphate group, in turn, is a molecule derived from phosphoric acid and is the only one that does not vary in each nucleotide.
