Our molecular tree has a length of 170 and our morphological tree has a length of 15. Which is preferred and why? a) Morphological. The traits used are more meaningful b) Molecular. There are more traits used and it is unambiguous. c) Morphological. It is more parsimonious d) Molecular. It is less parsimonious.

Answer from: dm0321545

The option that will be preferred is B. Molecular. There are more traits used and it is unambiguous.

It should be noted that the tree that has the fewest evolutionary changes will be the most parsimonious tree. This is the method that's used in phylogenetic analysis for the construction of trees.

Since the molecular tree has a length of 170 and our morphological tree has a length of 15, then the molecular approach will be vital as there are more traits that are used and it is unambiguous. The approach is also more accurate.

Answer from: stressedstudent101

The correct answer is - option B. Molecular. There are more traits used and it is unambiguous.

Explanation:

In this case, there is more than one trait is used, and for the phylogenetic analysis such a case, the molecular method is the best approach.

This method considers the origin of the species or phylogeny of particular species. The molecular approach is preferred for un-ambiguously and multiple traits are used in the molecular approach,

Answer from: Quest

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

Answer from: Quest

there's no big difference.

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
