a. parsimony; simplest; fewest
When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of <u>parsimony</u>, which means we choose the <u>simplest</u> possible hypothesis. In phylogenetic analysis, that means selecting the tree that represents the <u>fewest</u> evolutionary changes or mutations.
Explanation:
Phylogeny describes the evolutionary history of on organism or group of organisms.
A phylogenetic tree structure is used to describe the relationship between various organisms which have originated from common ancestors.
The Principle of Parsimony is best applied while constructing phylogenetic tree.
This principle emphasizes on simple observations on a phylogeny which requires only few changes or variations which explain for the difference between the phylogenic sequences.
This tree structure will only have few specific genetic variations or mutations or evolutionary changes which took place through new appearance of a trait or disappearance of an existing trait.
Explanation: Rivalry
There is safety in numbers, and with that, they can run together more often without the fear of being attacked, and must push themselves to match others, therefor getting fit
The overexpression results in increased micro vessel density and lesion size in mice with induced endometriosis.
Endometriosis is a benign gynecological disorder.
- it's far characterized through the ectopic presence of endometrial glands and stroma out of doors of the uterine hollow space and is carefully related to dysmenorrhea, pelvic pain, and subfertility.
- In endometriosis, the involvement of vascular endothelial mobile growth issue (VEGF) and different angiogenic mediators has long been recognized endometriotic angiogenesis entails numerous pathways and the blockade of simply one single pathway won't effectively suppress Endometriosis
- Slit is a secretory glycoprotein which include 3 members, Slit1, Slit2, and Slit3, and become at first found to be secreted repellents in axon steerage and neuronal migration It has been shown to be an endogenously available inhibitor of leukocyte chemotaxis.
- receptor for Slit is the protein Roundabout (ROBO), which currently includes 4 members (ROBO1-4)
