Answer:
Everything at some point belonged to a common ancestor, but these four species are considered to be like this because of similar ancestral traits that have been passed on to generations such a homologous pairs, vestigial structures, they are all mammals, similar amino acid sequences, vertebraes, etc.
Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. Many species have been shown to transition to obligate parthenogenesis over evolutionary time.
Animal Kingdom. One of the six kingdoms, characteristics include: heterotrophic (obtains energy from eating other organisms), multicellular, eukaryotic and cells have a nucleus but no cell wall or chloroplasts.
your blood which contains a lot of water, carries oxygen to all the cells in your body.
The nucleus is not the only source of DNA, besides it, DNA is also found in the mitochondria of all eukaryotic cells, as well as in the chloroplasts of plant cells and such DNA is called extrachromosomal DNA.
The DNA from the mitochondria (mtDNA) and chloroplasts are small and circular, which are similar to the prokaryotic DNA.
mtDNA contains its own genes that encode proteins that are part of the electron transport chain.
<span>Chloroplast DNA encodes for the components of the photosynthetic pathway.</span>
