Answer:
100% EE, 100% red eyes
Explanation:
For an organism, the genotype refers to the genetic characteristics of the organism while the phenotype refers to the physical characteristics of the organism.
The red eyes (E) is dominant while the white eyes (e) is recessive.
Since both parents are EE, the genotype of their offsprings would be EE, EE, EE, EE
That is: EE × EE = EE, EE, EE, EE
Hence the genotype is 100% EE.
Also, the phenotype is 100 red eyes.
Aim
When dividing the world into zoogeographical regions, Alfred Russel Wallace stipulated a set of criteria by which regions should be determined, foremost the use of generic rather than species distributions. Yet, recent updates of Wallace's scheme have not followed his reasoning, probably explaining in part the discrepancies found. Using a recently developed quantitative method, we evaluated the world's zoogeographical regions following his criteria as closely as possible.
Location
Global.
Methods
We subjected presence–absence data from range maps of birds, mammals and amphibians to an innovative clustering algorithm, affinity propagation. We used genera as our taxonomic rank, although species and familial ranks were also assessed, to evaluate how divergence from Wallace's criteria influences the results. We also accepted Wallace's argument that bats and migratory birds should be excluded (although he was contradictory about the birds) and devised a procedure to determine the optimal number of regions to eliminate subjectivity in delimiting the number of regions.
Results
Regions attained using genera (eight for mammals and birds and six for amphibians) strongly coincided with the regions proposed by Wallace. The regions for amphibians were nearly identical to Wallace's scheme, whereas we obtained two new ‘regions’ for mammals and two for birds that largely coincide with Wallace's subregions. As argued by Wallace, there are strong reasons not to consider these as being equivalent to the six main regions. Species distributions generated many small regions related to contemporary climate and vegetation patterns, whereas at the familial rank regions were very broad. The differences between our generic maps and Wallace's all involve areas which he identified as being uncertain in his regionalization.
Main conclusions
Despite more than 135 years of additional knowledge of distributions, the shuffling of generic concepts, and the development of computers and complex analytical techniques, Wallace's zoogeographical regions appear to be no less valid than they were when he proposed them. Recent studies re‐evaluating Wallace's scheme should not be considered updates as such because they have not followed Wallace's reasoning, and all computer‐based analyses, including this one, are subject to the vagaries of the particular methods used.
Answer: Lipid molecules.
Explanation: Biological membranes are bilayer of phospholipids that control the entrance and exit of molecules in the cells. The major components of phospholipids are the fatty acids. Phospholipids have two components: the fatty acyl chains and the phosphate group. The fatty acyl chains of the phospholipids molecules face each other at the core of the bilayer, forming a fluid hydrophobic interior while the phosphate (polar head) groups face outward. Proteins are embedded in this bilayer held by hydrophobic interactions between the membrane lipids and hydrophobic domains in the proteins. Both proteins and lipids move laterally in the plane of the bilayer but movement from one face of the bilayer to another is restricted.
