You observe a uniform tissue under a microscope. there is no lumen. the material looks densely packed, but you do not observe many nuclei. it appears that there are strands of fibers running in parallel directions. what type of tissue are you looking at?

Dense regular  connective tissue

Explanation:

Dense connective tissue is a type of connective tissue proper. It is characterized by the presence of more thick fibers which are densely packed.

The dense connective tissues have considerably fewer cells than loose connective tissue. There are three types of dense connective tissue.

Out of these three types, the dense regular connective tissue looks like a sheet and consists of bundles of collagen fibers arranged regularly and fibroblasts are present in rows between the collagen bundles.

Since the observed tissue is uniform in appearance and has densely packed material with fewer cells, it is the dense regular connective tissue.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
