Unculturable organisms one: a. cannot be studied, as they cannot be sampled and grown in the lab. b. can be examined using bioinformatic approaches using nucleic acid sequences. c. are characterized by extreme niche preferences. d. are very rare.

Ur answer is A. cannot be studied, as they cannot be sampled and grown in the lab.

A. cannot be studied, as they cannot be sampled and grown in the lab.

Explanation:

Unculturable organisms are organisms that cannot be studied, as they cannot be sampled and grown in the lab. This organisms survived in certain conditions that cannot be replicated in the lab for proper study some of this conditions are high salinity, high pressure and high and low pH.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
