Simora [160]

Choice D - stigma is the female part of the flower, but sepal is a protective part of the flower and not reproductive.

Choice C - "vary" is not a word, but it is a mistake and it should be "ovary,"  the answers could be both choice A and C.

Is extensive loss of hair observed in humans and whales an example of homoplasy or homology? see section 25.1 (page 497) ?
marin [14]
I believe that hair and limbs are homology because all mammals have hair and similar limb structure. Hair loss and social behavior on the other hand are homolasy because not all mammals have them. Homology is the similar traits due to common ancestry while homoplasy is similar traits for other reasons other than common ancestry.
