Answer:

Hey buddy here is your answer.......

Explanation:

7. A tissue is a group of cells, in close proximity, organized to perform one or more specific functions. There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

8.Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments.

9. Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, reptiles, birds, and the monotremes. In traditional usage, most insects, molluscs, and arachnids are also described as oviparous.
