Answer:
Biotic factor
Explanation:
Biotic factors are part of factors that determines the nature of the ecological system. They can either be living or dead organisms. Because they are considered to possess lives or had formerly existed, they are found in the biosphere and can reproduce.
Hence, to predict how the population of one species affects and is affected by the population size of another species or by its interactions with some abiotic factor, like rainfall. The ecological model uses a BIOTIC FACTOR.
This is because it is the interaction of the biotic and abiotic factors that determines the nature of the ecosystem.
Answer:
C. IBIB
D. IBiO
Explanation:
The blood group system comprises of three different kind of alleles, iA, iB, IO. As we know that a person gets two alleles for both traits, one from father and one from mother, and based on that a person gets its blood group. IA and IB are dominant to IO.
So, if a person has genotype IAIO he will have blood group A and if he has genotype IOIB he will have blood group B because A or B are dominant to O.
However, if a person has blood group O it means that he has genotype IOIO.
So, in this diagram we see that Eric has blood type O, which means that his genotype will be IOIO.
The Eric's mother Melissa has blood group B, which means that she can either had genotype IOIB and IBIB respectively.
Similarly, Eric's grandmother Tricia has genotype B which means that she can have genotype both IOIB and IBIB respectively.
Therefore, both C and D are correct options.
In a simple synapse, neurotransmitter chemicals are received by the postsynaptic membrane, also known as the dendritic membrane.
