In a wild-type neurospora , protein e (encoded by the haplosufficient gene "e") normally homodimerizes, and the e-e dimer catalyzes a biochemical reaction necessary for the production of a dark pigment. ed represents a mutant, dominant-negative allele of gene e. what is the predicted phenotype of a fungus cell of genotype e+/ed, and why? (a) wild type (normal production of the dark pigment), as ed is a negative allele (b) wild type (normal production of the dark pigment), as eis haplosufficient (c) mutanmutant (no pigment production), as the mutant allele ed is dominantt (no pigment production), as no e-e dimers will form in the heterozygote (d) mutant (no pigment production), as e is haplosufficient

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
