Answer:
Some scientists believe that there were huge fires and the skies were dark and full of pollution due to a meteor exploding and killing off the dinosaurs, and if it's true that this occurred, the Ostrich evolved to be a land animal due to it being too dangerous in the air for them. The long neck may have developed to help them get food that was higher up which is the same speculation for the Giraffe. To stay on land they had to be stronger, bigger, and faster than they were in flight.

Answer:
b. dNTPs lack a hydroxyl group on the 2' carbon of their ribose sugar.
Explanation:
Ribonucleotides (rNTPs) and deoxyribonucleotides (dNTPs) are the monomers for RNA and DNA respectively. Both are the nucleotides with a pentose sugar, a nitrogenous base, and a phosphate unit. The Ribonucleotides (rNTPs) and deoxyribonucleotides (dNTPs) differ from each other with respect to pentose sugar. The ribonucleotides (rNTPs) have ribose sugar while deoxyribonucleotides (dNTPs) have deoxyribose sugar. The deoxyribose sugar of dNTPs lacks hydroxyl group at 2' carbon which is otherwise present in the ribose sugar.
It's the first one where it resist change in pH solutions by neutralizing :)
