Answer:
b) Reptiles, birds, and some mammals produce amniote eggs.
Explanation:
All the mammals produce amniotic eggs. An amniotic egg is an egg that has four extraembryonic membranes including amnion. Amnion is a fluid-filled sac that serves as a cushion and does not allow the egg to desiccate. Since mammals are land animals, they have amniotic eggs to prevent any damage to the embryo from desiccation and physical injury.

Answer:
D. Nucleic acids attach to the bases in the DNA.
Explanation:
Transcription begins when an enzyme called RNA polymerase is added to the DNA template and begins a new chain a new chain to produce complementary RNA.
During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs.
RNA polymerase moves from the 3' end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA.
Therefore, D. Nucleic acids attach to the bases in the DNA.
When Scientists say that living Organisms share a universal genetic code it means, they all are evolved from the same Ancestor & hence, have some similar characteristic either functional or physcial
