Based on the morphology of Opalina and Volvox, which supports the syncytial hypothesis and colonial hypothesis of animal origin?

Briefly describe what endosymbiotic theory is.   Describe a few ways in which endosymbiotic theory has changed the way scientists think about the ancestral distinctions among the three domains.

Sequence data from OTUs are provided in the table below with values provided as (percentage distance x 1000) measurements. Determine the phylogenetic tree from the data in the table below using the UPGMA procedure mentioned in class.

Do not label the incorrect tree. Care Bear Gummi Bear Berenstain Bear Paddington Bear

Please give an example of convergent evolution relating to fungi.

Subject: Biology   Question: Why did the Homoscleromorpha move up from the Order to the Class level?

What is the advantage of a zoospore? It initiates karyogamy. It allows for asexual reproduction.  It can resist harsh conditions.  It allows for the formation of septa between nuclei.

Create a hypothetical phylogenetic tree.

Fungal Diversity Online Exercise Chapter 4 Reading Exercise contains information about the six species of mushroom-forming fungi shown below. Based on that information create some hypotheses explaining which species is the closest relative of Species A. You will later test the hypotheses by creating a phylogenetic tree. A B с 7
