a group of several kinds of  tissues working  together. is what?

Organ is a the correct answer but still if your wondering how it works look back in any basic biology text book where it talks about Levels of Organization.As anyliving thing unicellular to multicellular organism is based on level of organization.\nFor example, ORGANELLE-----CELLS--\n-TISSUE--ORGANs----ORGAN SYSTEM\nAs you already know Tissues are made up of cells rigth so what makes an organ is a group of tissues and in order to have organ system you need different organs a simple example is digestive system where you G.I.tract,stomach,intesitne,pancrea,liver,gall bladder all playing some important role in the functioning of the body.

The more advanced ones are:\nBilateral symmetry, unjointed appendages, endoskeleton, segmented body parts.

it depends on what you consider a body part... just bones?  bones and muscles?  And tendons... ligaments....

A group of organs that work together.  For example, the central nervous system:  brain, spine, nerves, etc....

Inside the body, the liver.\n\nSome would say in general it's the skin (which is made of several tissues).

Depending on how picky you want to be, the answer could be A or C.  By definition an organ is always composed of two or more tissue types.  Many organs contain all four major tissue types:  epithelial, connective, muscle, and nervous.  So A is certainly correct.  Since organ systems by definition are composed of two or more organs, they must also be composed of more than one tissue type.\n\nB is not correct because an organelle is a constituent of a single cell, which lies beneath tissues and organs in the hierarchy of organizational levels in complex multicellular organisms.  D could be correct if the organism in question is complex enough to have organs and organ systems.  On the other hand, simple forms of life such as bacteria and protists are also organisms, but being single-celled they obviously have not reached the level of organization at which tissues and organs are found.

This is a problem. Medical dictionaries define an organ as a relatively independent part of the body that carries out 1 or more special functions. Lists of internal organs usually list 22. The skin would make 23. Eyes and ears are certainly organs and in the skin are sense organs. So there isn't a definite answer or an official answer.

The skin. Although it is tissue, organs are just groups of tissues.

Most tissues in the human body contain differentiated cells that actually perform the function of the tissue and a population of undifferentiated cells that can take over some part of the function of that tissue should it be damaged. For this reason, many human tissues, such as liver, skin, and skeletal muscle tissue, are capable of repairing themselves if sufficient healthy tissue remains to replace the damaged parts.\n\nOther tissues seem to lack a population of undifferentiated cells (at least in adults) and generally do not regenerate. Tissues in this category include heart muscle, nerve tissue, and kidneys. So, among the cells that are least likely to be replaced by other cells in the human body are cardiac muscle cells, neurons, and the cells that make up the nephrons.

if ur talking about cells... i think it is organelles...not sure

This is when the body begins to break down the clot and fibroblasts start to organise it by creating a matrix of fibrous tissue throughout it.
