Biologists use various types of data, such as gene sequences and structural Biology Assignment Help

Question Get Answer Biologists use various types of data, such as gene sequences and structural features, to construct phylogenetic trees (also referred to as cladograms). This can be a challenging process that is akin to reconstructing a crime scene well after the crime has taken place. Although a thorough treatise of phylogenetic reconstruction is beyond the scope of this lab, we will incorporate some basic concepts. Consider the table below which lists organisms from several different taxa as well as the presence or absence of several different characters (a ” ” indicates the organism has that character). Research has shown that a group of organisms in the Kingdom Protista called choanoflagellates resemble sponges in many ways. For example, they are sessile and consist of colonies of cells that are nearly identical to many of the cells that make up sponges. Choanoflagellates are colonial, but not multicellular. Therefore, choanoflagellates are considered the closest living relatives to animals and “multicellularity” represents a key feature that separates animals from the protists they likely evolved from. 1. ? Based solely on the information above and data in the table below, which group of animals (i.e., taxon) likely represents the first group to evolve from protists? Is it accurate to describe that group as “inferior” in any way to the other taxa listed below? Explain.

You will be investigating skin disorders and the clinical signs of diseases in nails.  Produce a Word or .pdf document and upload it below.   Each submission must be at least 300 words and be written in your own words. Your submission must pass a Turnitin originality check (less than 20% similarity) in order to earn a grade. Turnitin will allow 3 submissions within a 24 hour period so you can check your similarity score.  Your submission must include APA citations.  Your assignment must include the following:  1. Choose a skin disorder and describe how the structure of the skin is affected by the disorder. Also include the disease, signs, symptoms, and treatment.  2. Name at least 3 diseases that might be suspected based on the look of one’s nails. Describe the condition of the nails and what disease or disorder it may point to.

What is the relationship between natural selection and sexual selection? Are they the same thing?

BiologyQuestion Get Answer Define sexual selection:

What is the relationship between natural selection and sexual selection? Are they the same thing? Is one a specific category of the other?Give a specific example of sexual selection:Sexual selection might lead to traits that lower an animal’s ability to survive. For example, a male peacock would be easy prey for a predator—he can’t run and he can’t hide. How could a trait like this evolve with natural selection?Define coevolution:

A cross was made between a Neurospora strain that has the genotype

Question A cross was made between a Neurospora strain that has the genotype (a b ) and a strain that has the genotype ( c) and 2500 ordered tetrads were obtained (see below). Determine which genes are linked, the distance between the linked genes, and the distance between each gene and its centromere. Draw any relevant map(s) being sure that they are consistent with the mapping data.
