Answer: D. Add water features to private gardens.
Renewable resources are those which can be replenished after one or subsequent uses. Examples include oxygen, fresh water, solar energy and biomass. Adding water features to private gardens can be a mode of replenishing freshwater. A system which can absorb the water which is being supplied to plants in the garden through soil and collect this water as a reservoir in the form of groundwater.

He went to the Galapagos Islands and studied different species of finches and plants that had adapted differently on the different islands.
Answer:
F1
A A
a Aa Aa
a Aa Aa
All the offspring have flower located at axial position
F2
A a
A AA Aa
a Aa aa
Three offspring with genotype i,e Aa, Aa and Aa will have flower located at axial position
Only offspring with genotype "aa" will have flower located at terminal position
Explanation:
Let the allele "A" represent the characteristics of axial position of flower
Let the allele "a" represent the characteristics of terminal position of flower
Given -
"A" is dominant over "a"
F1 generation -
Two parents with homozygous genotype for both A and a are crossed . The punnet square for the cross between "AA" and "aa" is as follows -
A A
a Aa Aa
a Aa Aa
Thus the genotype of offspring is "Aa"
Since, "A" is dominant over "a", all the offspring have flower located at axial position
F2 generation-
The cross between two parents having heterozygous genotype "Aa" will take place .
The punnet square for the cross between "Aa" and "Aa" is as follows -
A a
A AA Aa
a Aa aa
Three offspring with genotype i,e Aa, Aa and Aa will have flower located at axial position
Only offspring with genotype "aa" will have flower located at terminal position
From mouth/nose, the air passes to the trachea (the wind pipe), there it enters (sequentially) the bronchi, bronchioles (small pipe-like structures), alveoli (widened empty sacs), the walls of which are in close contact with the blood vessels which contain the RBCs, which in turn contain the protein--hemoglobin, which binds to the oxygen present in the freshly inhaled air, and loses the carbondioide present DISSOLVED in the blood. This bound oxygen goes to the heart (of course along with the RBCs in the blood), from there to the smaller and smaller arteries, then to the capillaries, where again oxygen is lost to the surrounding tissue fluid, from where the cells collect oxygen by simple diffusion, and lose carbon dioxide, which gets dissolved in the water present in the blood.
From here the blood, with hemoglobin poorer in oxygen, and richer again in carbondioxide goes to the venules, and veins (capillaries continue as venules), which become successively larger to become superior and inferior vena cava and enter the right atrium, and then from there the blood again goes to the lungs and comes in contact with fresh air in the alveoli.
