Nematodes are roundworms that are incredibly diverse and, as a group, have adapted to survive in all environments. Which of the following statements accurately describes the DNA of both groups? * pdates ades embers nferences The spirochaete genome is smaller than the nematode genome. Q Online Nematode DNA is circular. sela Spirochaete chromosomes are composed of just DNA while nematode chromosomes also include specialized proteins. on Periods 1 and 2 eriods MP1, Highschool chool MP3, Spirochaete DNA is linear. MP4 Operons are clusters of genes that are regulated as a group. They can be characterized as either repressible or inducible. What is the main difference between the two? * d Thu Fri INTL 1To explain: The DNA sequence of a modern bacterium which is believed to be descended from endosymbiont which gave rise to mitochondria would be similar to chloroplast, nucleus or mitochondrion.

- The diagram represents a possible phylogenetic tree showing the relationship between the four species: M, L, S, and R. A M LS R V What is the plausible explanation for the appearance of autapomorphic character c in species L and S of tree A although they do not share a most recent common ancestor?What general term describes any character state that is modified relative to an ancestor? 1 options: uniquely derived state ancestral state shared derived state derived stateImagine that you have the DNA sequences fromthe intron of a gene in three species called A, B,and C. Species A and B are most closely related,while C is more distantly related. The sequencesof A and B differ by 18 base pairs, A and C differby 26 base pairs, and B and C differ by 28 basepairs. Fossils show that species A and B divergedabout 1.2 Mya, but there is no fossil evidence asto when the most recent common ancestor ofall three species lived. Use the genetic data toestimate that date. What assumptions are youmaking to get this estimate?
- Which species on the chart (A,B,C,D,E,F,) is the common ancestorIn Oct 2022, a chilling discovery was made in Vuvatu, a country known for its extensive volcanic landscapes. Scientists found the remains of a large organism that had no resemblance to any current form of life on Earth. The organism also had no resemblance to any fossils ever found, including the very few fossils ever recovered from Vuvatu (fossils are rarely ever found in Vuvatu since volcanic landscapes are generally not conducive of fossilization). The world buzzed with the possibility that this was a crash site for an extraterrestrial body. An extensive study of the uncovered remains was conducted by many research facilities. Their conclusions regarding the organism’s features are listed below: Physical features: The organism has a surprisingly soft and malleable exoskeleton that reflects ambient light, creating mesmerizing patterns. In fact, the remains highly suggest that most of its body parts are soft and blubbery rather than rigid. Habitat: Given its relationship with…In Oct 2022, a chilling discovery was made in Vuvatu, a country known for its extensive volcanic landscapes.
