Answer:
iAiA and iBiB
Explanation:
Blood type in humans is controlled by a gene with three alleles namely: iA, iB, and i. Alleles iA and iB are dominant over allele 'i' but codominant. The following are the allelic combinations of the genotype and the resulting blood types:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, one parent has type A blood and the other has type B. If all the offsprings of these parents have blood type AB, this means that the parents must have a genotype of iAiA and iBiB respectively.
Answer:
Ecology is the study of interactions between organisms and their surround- ings including other organisms. Organisms grow, multiply, occupy different regions, compete with others for resources, prey upon others, transform into different species etc. Many interesting questions can be asked of this broad canvass.
Explanation:
The answer is B. Invasive species are successful in novel environments due to lack of a natural predator or competition. Therefore if the non-native share a niche with other fish in the lake ecosysem, there will definitely be competition for resources. This could lead to competitive exclusion of one species or resource partitioning between the species. Consequently, the non-native fish species will not invade the new environment unchecked.
They are the same thing, but there's also carbon dioxide in the ocean, dissolved as carbonic acid. Carbon dioxide literally means one carbon, two oxygens. CO2.
