The answer is B. Vascular plants and invertebrates appeared during this time.
It is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand.
- Deoxyribonucleic acid (DNA) is a biological molecule with two strands. Each strand is made up of a sequence of nucleotides. The DNA nucleotides are Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).
- In a DNA molecule, Adenine forms an hydrogen bond with Thymine i.e. A-T, while Guanine forms an hydrogen bond with Cytosine i.e. G-C.
- Therefore, it is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand. For example, a strand with ATGCGTACGAT will form the following sequence: TACGCATGCTA

Only one type of cell was given, but different types of cells are structured differently in response to what function they need to perform.
For example, muscle cells are like that because they need to be flexible. Bone cells, however, are compact. This is because bone cells need to be durable, to keep the body together.
