The answer should be C, 50%
First we need to find the alleles for Mr Jones. We know that he has a blood type B, so at least one allele should be B, and the other can either be B or O (cannot be A, or else his blood type would be AB because A and B are co-dominant alleles)
Since Mr Jones' parents are both blood type AB, so which means their allels must be A and B, so, we can conclude that Mr Jones alleles should be B and B.
Now we know Mr jones' alleles, we can conduct a punnett square to find the probability. Since Mrs Jones has blood type AB, again, her alleles are also A and B.
From the punnett square attached, we can conclude that their offspring are either blood type AB or pure B. So, the answer should be 50%, C.
When a substance becomes part of a mixture, its chemical properties ONLY change if the resulting mixture is homogeneous. Otherwise nothing happens to the properties.
Explanation:
The formula of a selected pure substance doesn't amendment simply because it becomes a part of a mix. Chemical properties can amendment in a very mixture. If you've got a mix of water and alcohol, the melting point are below 0C. That doesn't mean that water now not freezes at 0C, it simply means that the mixture of water and alcohol doesn't freeze at 0C.
Answer:
plasmolysis is the shrinkage of protoplast from the cell wall under the influence of a hypertonic solution.this can be observed by placing the fresh filament of spirogyra in a 10% solution of common salt.the cell undergoes exomosis.
I hope this helps
