Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. Many species have been shown to transition to obligate parthenogenesis over evolutionary time.
ATP or NADAP which is cycled
Answer;
The correct answer would be Rr.
In a monohybrid cross, the phenotype ratio of 3:1 is obtained only when both the parents are heterozygous for the trait.
In this condition, the heterozygous genotype would be Rr. The phenotype of both the parents would be round seeds (R) as the round is a dominant trait.
The cross of these parents would produce offspring with three types of genotypes RR, Rr, and rr in ratio 1:2:1.
Thus, the phenotypic ratio would come out to be 3 (round seed):1 (wrinkled seed).
Answer: Operant Conditioning
Some bears must have had undergone operant conditioning that is why they open their mouths for teeth cleaning and present their paws for nail clipping.
Operant conditioning is a form of learning in which a reward or punishment is given for some voluntary behavior.
Bears that have undergone operant conditioning are called food-conditioned bears. They are dangerous but learned to approach humans, or frequent human-occupied sites, in search of food (reward).
