In the fruit fly, Drosophila melanogaster, a spineless (sp, no wing bristles) female fly is mated to a male that is claret (cl, dark eyes) and hairless (h, no thoracic bristles). Phenotypically wild type F1 female progeny were mated to fully homozygous (mutant) males and the following progeny (1000 total) were observed. PHENOTYPES NUMBER OBSERVED spineless 316 wild 8 claret, spineless 136 claret 37 claret, hairless 304 hairless, claret, spineless 12 hairless 144 hairless, spineless 43 What is the correct gene map for these genes

protocol for imps extraction focusing on membrane protein extraction, solubilisation, and purification.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

it should be d) transitional fossils.

they show the gradualism of evolution throughout a period of time
