Small intestine
Peyer's patch are small masses of lymphatic tissue found usually in the ileum region of the small intestine. This is an aggregated lymphoid nodules and form an important function in immune system. This allows to monitor bacterial population and prevents the growth of pathogenic flora in the intestine. They are egg shaped lymphatic tissue that are similar to lymph nodes in structure except the absence of connective tissue.
Nutrients in coral reefs are recycling efficiently because the water is so shallow. Coral reefs are generally located along tropical coastlines, in open ocean deserts. They thrive in tropical, low nutrient waters because there is no phytoplankton in there. They are home to a large number of species,

Answer:
The most appropriate answer would be taxonomy.
Taxonomy is the branch of science that deals with identification and classification of different organisms.
It mainly classifies different organisms into 8 main taxa or groups. The principal ranks used in modern taxonomic hierarchy are
- Domain
- Kingdom
- Phylum (division is used in botany)
- Class
- Order
- Family
- Genus
- Species.
It used various principles to identify and classify an organisms such as cellular organisation, mode of nutrition, mode of reproduction, phylogentic or evolutionary relationships et cetera.
Answer:
The correct answer would be -9 normal : 3 striped : 3 spotted : 1 striped and spotted.
Explanation:
As the F1 progeny have no stripes or spots considered as normal, it means normal head and normal tail are dominant on their alternative traits. So, it is clear that the F1 progeny are heterozygous for both of the traits.
Henece the cross between the two F1 progeny is dihybrid cross of hetrozygous lizards which produces offspring in 9:3:3:1 ratio, where 9 are normal, 3 striped (dominant in one character), 3 spoted (dominant in other) , and 1 will be stripped and spotted (recessive).
Thus, the correct answer is - 9 normal : 3 striped : 3 spotted : 1 striped and spotted.
