What is the difference between a collagen fiber and a collagen fibril?
Collagen fiber is a larger structure composed of multiple collagen fibrils, which are thin, elongated structures. Fibrils are bundled together to form fibers, providing structural support and strength to tissues in the body.
Which of the following are responsible for the differences between species and for differences between individuals in the same population?
Genetic variations, which arise from mutations and recombination of genetic material during reproduction, are responsible for the differences between species and between individuals in the same population. These variations can lead to differences in physical traits, behaviors, and other characteristics among organisms. Additionally, environmental factors can influence the expression of these genetic differences, leading to further diversity within and between populations.
What white fiber tract communicates between the hemispheres?
The corpus callosum is the white fiber tract that connects the left and right hemispheres of the brain and facilitates communication between them. It allows for the exchange of information and coordination of functions between the two hemispheres.
What term do scholars use to refer to biological differences between man and woman?
Scholars use the term "sexual dimorphism" to refer to biological differences between men and women. This term encompasses differences in physical characteristics such as body structure, reproductive anatomy, and hormonal profiles.
What allows for differences between individuals due to differences in inherited DNA?
Genetic variation, which is the differences in DNA sequences among individuals, allows for differences in inherited traits between individuals. This variation is the result of mutations, genetic recombination, and other processes that create unique combinations of genes in each individual. These genetic differences are responsible for the individuality and diversity seen within a population.
