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.

From smallest to largest. That will be
Cell; cheek cell

Organism; lion
Tissue is a group of cells, an organ is a group of tissues, a system is a group of organs, an organism is a group of systems
Hope that helped. Have a nice day
The advantage of having the autonomic nervous system (ans) neuron that exits the cord synapse onto a second neuron before the target cell shows regulation.
A synapse is in charge of allowing a chemical or electrical signal to travel from one neuron to another or to the intended cell. Synapses are essential for tying together sensory organs, particularly those that track down and send pain or touch inputs to the brain. Chemical and electrical synapses are two different kinds of synapses.
Through the synapse on the second neuron, the autonomic nervous system (ANS) is able to regulate the physiological functions of other systems. This implies that every component of the physiological processes can be separately controlled by the ANS.
