The tissue type repsonsible for protection of the body from the external environment?
-skin, epithelium or integument?

I am thinking epithehelium
Which best explains why long bones are hollowin themiddle?
- lighten them, Wolff's law (absence of load)?
Which about collagen is FALSE?
- formed by macromolecular assembly of procallagen, produced by enzymes, or its slight crimp give it elasticity independent of elastin?
Which is false?
- primary cell in fibrocaritlage is fibrochondrocyte or , primary celll type in skeletal muscle is myofibre?
Which tissue best resit tensile pure force?
- tendon, muscle elastic cartilage or fibrocartilage?
Which does not describe how animal reduce heat loss in cold environment?
- brown adpose tissu, or decrease body temp or countercurrent mechanisms?

1) I would guess the first in charge... Why use just the other one?

2) what about strength of the bones?

3) I think the procollagen thing...

4) -cyte is for sure not primery cell, it should be -blast; but also in musles it should be myoblast


6) decrease of body temp (brown adipose tissue increases body temp and heat loss)

Cis or trans? That's what matters.
