Chapter 23, Problem 8RQ

In 2016, scientists published the genome of Monoceiconionoides, and demonstrated that this organism has no detectable mitochondrial genes. However, its genome was arranged in linear chromosomes wrapped around histones which are contained within the nucleus. Monoceiconionoides is therefore a(n).

Why is it favorable for protozoa to replicate with schizogony versus using simple mitosis? what are the different scenarios that can occur with regards to bacterial growth within a thioglycolate tube? Explain why certain bacteria require one classification versus a different classification. A botanist has been using betaproteobacteria to grow his herb garden, because betaproteobacteria require little nutrients to grow. His garden does not grow successfully, so he comes to you for help to develop the herb garden.  Which class of gram negative bacteria would you suggest and why?  Why was the botanist’s original idea not going to work?
. The endosymbiotic hypothesis for the origin of mitochondria from gram-negative prokaryotes is supported by all of the following lines of evidence except: A. the presence of enzymes for the Krebs cycle, electron transport, and oxidative phosphorylation the presence of mRNA, tRNA, and rRNA similar to that of the a-proteobacteria the presence of 80s ribosomes, consisting of 40s and 60s ribosomal subunits the presence of circular DNA resembling that of aerobic proteobacteria their use of binary fission rather than mitosis during cell division
. Single-celled organisms with a true nucleus, ester-linked fatty acids in their G-3-P cell membranes, and histones, but no collagen, and no cell walls composed of either chitin or cellulose, must be: members of kingdom Archaeobacteria members of kingdom Protista members of kingdom Eubacteria members of kingdom Fungi members of kingdom Animalia
