Question A, B, O blood types in humans demonstrate the phenomena known as co-dominance. The blood Rh factor (+ or -) displays an inheritance pattern of simple dominance. Using the following designations: A as the dominant allele for blood type A, B as the dominant allele for blood type B and o as the recessive allele for blood type O and R as the dominant (+) Rh allele and r as the recessive (-) Rh allele, what are all of the possible genotypes for the following blood types. a) A+
b) O+
c) B-
d) AB-
e) If one parent has the blood type A+ and another parent has O+ blood, what are the possible blood types of their children?

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.

Many plants can reproduce asexually. which of these is an example of asexual reproduction in a plant? a. pine cones forming on a tree b. cross-pollination in a tomato c. roots sprouting from a potato d. night-blooming jasmine flowers
