Which of the following is not found in an animal cell?
tight junctions
plasmodesmata
desmosomes
gap junctions

Answer 1

1. During anaphase I of meiosis I, the chromosomes that are separating are **homologous pairs**. Anaphase I is characterized by the separation of homologous chromosomes, with each chromosome consisting of two sister chromatids.

2. The last component of aerobic respiration is the **electron transport chain**. This is where the majority of ATP is produced in aerobic respiration.

3. The structure that is not found in an animal cell is **plasmodesmata**. Plasmodesmata are channels that allow for communication between plant cells, and they are not present in animal cells.
