1)Why is it important to have holotypes for species?
2)How is the Scala naturae (or great chain of being) different from a phylogenetic tree?
3)Why is Binomial Nomenclature such a useful and needed tool in systematics and taxonomy?
1.Holotype is a valuable original specimen that describes a new species.When species is formally described, scientists often base that description on a single specimen and this specimen is preserved to be made available for other researchers.
2.Scala naturae is an obsolete concept that life was organised in a linear hierarchy with organism increasing in perfection from lower to higher forms wheras phylogenetic tree is a branching diagram showing the evolutionary relationship among various biological species based upon similarities and diff in physical or genetic che.
3.Binomial nomenclature is important because each organism has given a name containing genus and species which is constant all over the world i.e. easy to describe any organism by this name without any confusion.

Give at least one specific example. 4. How has the excessive use of antibiotics resulted in a major global problem? 5. How are plants and animals dependent on each other? Give some specific examples. 6. What do the fungi and animals have in common? 7. Which types...
I need help with these questions I answered my original answer is found below, the professor marked it incorrect/ and or insufficient answer. 1)Why are phylogenetic trees based on molecular/ genetic data more reliable than trees based on morphology? - The morphological phylogenetic tree is quantitative data. This means physical characteristics; therefore, this is not the tree that would be a close representation of the true phylogenetic tree. Molecular phylogenetic trees, use DNA or RNA/ protein sequences. This makes Molecular...
3. In determining whether different nonhuman primate species have culture, how important do you consider the ability to transmit cultural behaviors and knowledge across generations? In other words, how comparable would you consider the cultures of humans and nonhuman primates? Explain why you feel the way you do.
Part B Directions Read Ch. 1 section 1.2 (pp. 4-10) and Ch. 19 1.Think about the origin of cellular life forms beginning from 4.5 billion years ago and continuing up to the point that eukaryotic cells appeared. Consider: Why is RNA thought to be the 1st self-replicating biomolecule? • Describe the endosymbiotic hypothesis and explain how it accounts for the origin of mitochondria, hydrogenosomes and chloroplasts. List at least 2 pieces of evidence that support this hypothesis. 2. Explain in...
1. why might a protein have multiple domains. 2.why a protein might be comprised of more than one chain. 3.why a protein structure might show gaps when the real protein has none. 4.why a protein might bind nucleic acids. 5.why a protein might have disulfide bonds. 6. are ligands important for function or just artifacts of the structure process? 7. Why would the surface of a membrane-bound protein have a different polarity from a soluble one?
could somebody pleas help me with these 3 questions? thank
you!
2. Research into the origins of life on Earth is based on laboratory observations that mimic hypothesized conditions on early earth. Which of the following has not been observed in laboratory experiments? A. Spontaneous formation of amino acids, simple sugars, and nucleotides from abiotic components B. Reactions catalyzed by RNA molecules isolated from pre-existing cells C. Spontaneous formation self-replicating RNA molecules from abiotic components D. Spontaneous formation of membranes...

Give 3-4 reasons explaining why the Kasaki cluster with
sequences have 3 different species names
Why species 1, 2, and 3 is in the middle of the Kasaki cluster.
The relationship with Kasaki nozomi sp. (above), Kasaki sp.
(below), Kasaki mizore sp. and so on
Keywords: common ancestor, same species / different species, are
species 1-3 new species, relatedness (which one is more related,
which is less), branches.
Hint: anatomically, species 1-3 have similar morphology as the
Kasaki sp. (these...
