A group of similar cells that perform a particular function is called a tissue.
There are different kinds of tissues in both plants and animals. In man, there are four major types of tissue.
1. Muscle tissue - made up of cell that are long and fibrous. The muscle cells are able to contract.

Explanation:
Answer:
Most restriction enzymes recognize sequences of 20-25 bp in length
Explanation:
Sequences of DNA that are recognized by restriction enzymes are called recognition (or restriction) sites are usually are between 4 and 8 bases long. Many of them are palindromic, which means that they are the same when you read it backwards and forwards (mirror-like).
Restriction enzymes are endonucleases, which means they cut phosphodiiester bonds within DNA. These enzymes are from prokaryotic organisms (archea and bacteria) which use them as defending mechanism against viruses. Prokaryotes protect their own DNA via methylation, performed by methyltransferase.
mostly collagen and some calcium phosphate
Answer: no body cavity—acoelomates; body cavity not completely lined with mesoderm—pseudocoelomates; body cavity completely lined with mesoderm—coelomates
