Atissue is a functional grouping of similar cells that are joined together to form functional sheets or cords of cells. a tissue is a functional grouping of similar cells that are joined together to form functional sheets or cords of cells. a. true b. false

The answer is true.

A tissue is a level of organization in multicellular organisms and it represents the group of structurally and functionally similar cells. A tissue is not only the simple group of cells, it is an ensemble of similar cells and their extracellular matrix that together carry out a specific function. Functional grouping of multiple tissues in structural units, compose organs.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
