Made-up of beta-sheets

Four adjacent antiparallel strands linked by loops

Three anti-parallel beta sheets are connected 3 loops

The pattern is similar to ornamental pattern used I ancient Greece, therefore called as Greek Key motif

T1 cells are mIgMhi, mIgD -/lo, CD21-, CD23-, CD24+, and CD93+. 

T2 cells differ from T1 cells in having higher levels of mIgD and in expressing CD21 and CD23.

Reproductive strategies

1.Semelparity

2.Iteroparity

Semelparity - When organisms reproduce only once during their life

Ex- insects, other invertebrates, and occurs in organisms such as salmon, bamboo grasses, and agave plants

Iteroparity - When organisms reproduce multiple times during their life.

It is common in most vertebrates and perennial plants, such as trees
