Mammals first appeared
Explanation:
The dinosaurs became extinct one million years after the Cenozoic era started. The mammals first appeared as the modern culture first appeared in that era.
Explanation:
<u>a. The genes in the DNA instruct the cell to make proteins.</u>
Genes are a set of coded instructions in the form of DNA, which are crucial to cell regulation - these enable protein synthesis.
Further Explanation:
Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and carry out protein synthesis.
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

For example, first, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
Hope this helps! :D
Answer/Explanation:
Onions are stem modifications of bulbs. Onions grow during a cold weather, but forms bulbs when the weather is warm. Onions can either be grown using seeds or through their bulbs. That is why, the stem modification of onions are bulbs. Tuber is from potatoes, whereas corm is from crocuses and gladioli.
