Jean- Baptiste Lamarck said that organisms work toward perfection, acquire the physical traits that their parents had, and if they don't use some body part then it will disappear. ... could be generalized to any population of organisms.
The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
Hope this helps :)
Answer:
Explanation:
Well sorted sediments, evenly distributed sediments of uniform size, typically contain 26% to 48% open space. ... Thus, well sorted sediments have higher porosity while poorly sorted sediments have low porosity. Permeability refers to how easily water passes through sediments and rock.
These structures have the function to move around.
