Question

Help asap please!?

1.In binomial nomenclature of organisms, every species name includes two words. The first word is the name of the _______.
2.A monophyletic group or clade consists of a single _______ and all of its descendants.

3.Cladograms sometimes indicate _______, or shared characteristics. All species have that characteristic from the indicated point forward.


4.What's our system of naming organisms called, and what are the two most specific categories of organization?

5.If a scientist is studying the evolutionary relationship between two species of birds, what tool could she use to help her chart their relationship?

6.How is one clade differentiated from another clade?

7.Which type of character provides useful data for cladistic analysis?

8.What technological development allowed for a more detailed understanding of the relationship between species?

Answer 1

1) genus

2) organism

3) clade

4) the system of naming organism is called binominal nomenclature while the two most specific categories of organization is genus and species the genus is the first and species is the second

5) the tool used to help her chat their relationship is a phylogeny

6) A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. Using a phylogeny, it is easy to tell if a group of lineages forms a clade.

Step-by-step explanation:

Answer 2

1. Genus

2. Common ancestor

3. Synapomorphies

4. The system is called binomial nomenclature, and the specific categories used are genus and species.

5. The scientist could use a phylogenetic tree to help visualize the evolutionary relationship.

6. One clade is differentiated from another clade by a branching point within the phylogenetic tree that's defined by some character or characters.

7. Since cladistics depict an evolutionary relationship between organisms, the traits that are studied and categorized are homologous traits.

8. DNA sequencing is the technological development that allowed scientists to gain a more complete understanding of the relationships between species.
