"The curling direction in snails is delayed a generation in its expression. The offspring of a snail are phenotypically the phenotype dictated by the genotype of the mother. Dextral curling (shell opens to the right) is dominant to sinistral curling (shell opens to the left). A cross between a homozygous sinistral female snail and a homozygous dextral male resulted in sinistral F1 progeny. If an F1 sinistral female is crossed to an F1 sinistral male, what progeny phenotypes are expected in the F2?"

What is one function of the embedded proteins

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression.c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression.d-neelaredoxin is only produced when there is exposure to o2 or h2o2.

Anne, an intern in a microbiology lab, was observing the characteristics of various specimens of protists. match each specimen to the category of protist to which it belongs.
