What is the working definition of an animal? - Animals are multicellular eukaryotes that are heterotrophic and undergo a blastula stage Two problems associated with morphological classification? - 1. Convergent evolution 2. Minor mutations Why was the organism found in the 90s labelled as a bivalve mollusc? - Because it was consuming bivalve eggs and had traces of their DNA in its gut. What are some problems with molecular sequencing? - 1. Differences in mitochondrial and nuclear DNA ...

development the changes the zygote undergoes as it develops into an adult organism embryology development of embryo 3 processes of development cleavage, growth, differentiation cleavage a series of rapid mitotic division what division does embryology do? mitosis what happens in cleavage? -DNA is copied -cells divide into two identical ones(diploid) -The number of cells increases -cells do not grow -since the egg is large and now need to return to th...

animals - multicellular, heterotrophic eukaryotes with tissues developed from embryonic layers collagen - the most abundant structural protein that helds together the animal cells cleavage - The process of cytokinesis in animal cells, characterized by pinching of the plasma membrane; specifically, the succession of rapid cell divisions without growth during early embryonic development that converts the zygote into a ball of cells. blastula - The hollow ball of cells marking the end stage of...
