Egg Lab Report Introduction: An egg is a model of a human because the egg has a cell membrane like humans do inside and outside of the body that let things pass through like water. We can use eggs to study the effect of changes in the external environment on the internal environment by having harsh environments like putting the egg in only alcohol and see what happens to the inside of the egg. Diffusion is the movement of a substance down its concentration gradient from a more to a less concentrated

Because chlorophyll-A is more polar than ß-carotene and less polar than chlorophyll-B‚ this observation is reasonable. Introduction ß-carotene is a yellow-orange pigment found primarily in fruits and vegetables. ß-carotene is a carotenoid that is effective in preventing sunburn in sun-sensitive people‚ reducing the risk of breast cancer and other diseases‚ preventing asthma

Introduction: To achieve genetic experiments with haploid organisms‚ genetic strains of different genotypes must be crossed from one another. Following fertilization and meiosis‚ the meiotic products can be analyzed as the ascomycete fungus‚ Sordaria fimicola. Sordaria can be used as a model to study meiotic segregation. The trait followed was the ascospore color. Ascospore color is a single gene trait therefore it is easily observed under a light microspore. Which allele is dominant is very tough
