It’s a little-known fact that cotton absorbs 27 times its weight in water, an ideal choice as a towel, but when it comes to your bedding, it is absorbing the moisture out of your skin and hair causing it to lose lustre and hydration. Silk on the other hand, has a similar pH level to your skin and absorbs very little (0

Although selection of the appropriate suture material is important, so is the surgical technique used to close the wound. Good surgical technique is mandatory because it significantly affects outcome. Proper placement of sutures allows precise approximation of the wound’s edges, which helps minimize and distribute tensional forces on skin.

Why does the fitness of a phenotype depend on frequency-dependent selection? A) Because frequency-dependent selection acts against extreme phenotypes. B) Because the least number of alleles are at that locus. C) Because selection favors the least common phenotype. D) Because sexual selection produces dimorphism.

answer choices. Sharp reduction in population size due to an environmental disaster, often results in loss of variation. When individuals survive and reproduce at a higher rate than others in the same population. Process by which populations have become adapted to their environment over time.

By acting entirely within a species, disruptive selection is of particular interest because it could contribute to the evolution of reproductive isolation and sympatric speciation by sexual selection, a phenomenon that currently remains controversial in evolutionary biology (Gavrilets and Hayashi, 2005, van Doorn et al., 2004).

Why does silk thickness matter in plants?

The length of the silk is important in creating high-quality fabric. Long fibers make long, smooth surfaces, which is why silk reflects light and has that special luster we value. But, short fibers and broken fibers may also be spun to create lower quality fabrics. For all its delicacy, silk is as strong as the wire of equal thickness.

Our results suggest that changes in silk protein structures do not affect silk colour via variation in the silk's refractivity or birefringence. We thus expect the most likely cause of the yellow or white coloration observed in T. plumipes silk to be pigment deposition, as has been speculated for Trichonephila clavipes [ 6 , 37 ].
