In nature, there is an exception to every rule. of the species below, which one has a very unusual genome that violates the "rule"? a. borrelia burgdorferi, the bacterium responsible for lyme disease, has a linear genome and up to 21 plasmids. b. e. coli, a common bacterium in the human intestine, has dna nucleotides a, t, c, and g, with only one oh group on the sugar moiety. c. humans have a genome formed from 23 pairs of linear chromosomes, each of which is so long that it must be wrapped up and condensed into a special structure to fit in the nucleus. d. arabidopsis pollen is haploid, carrying only one copy each of five linear chromosomes.

Option (A).

Explanation:

Genome may be defined as the haploid set of the chromosomes of the organisms. DNA is present as genetic material in all the organisms except some viruses.

Borrelia burgdorferi has an unusual genome because they have segmented genome and consists of linear replicons. The 21 plasmids or extra chromosomal DNA is also present in this organism.

Thus, the correct answer is option (A).

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
