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.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
