Answer:
Option B, The parents supplied different alleles
Explanation:
The genotype of any offspring is decided by the equal contribution of allele from both the parents. Hence, even when an organism is heterogyzous it is clear that the allele pair expressing the trait (due to the heterozygous pair) is formed by the contribution of both the parents equally which means one allele is given by one parent while other allele is given by other parent.
For instance -
For any heterozygous allele pair let’s say “Xx” , allele “X” would be donated by one parent while allele “x” would be donated by another parents.
Hence in order to form a heterozygous offspring the two parents need to contribute different alleles.
Therefore, option B is the correct answer
Answer:
The answer is the dropping pH of the ocean
Explanation:
The ocean absorbs tons of carbon dioxide (Co2) from the atmosphere which changes the chemistry of the water. The ocean is naturally Alkaline but, as the oceans absorb Co2 it turns into carbolic acid. This doesn't make the ocean's immediately acidic but it is causing them to be gradually less alkaline. Since the direction of change is near the acid end of the scale, the process is known as ocean acidification. The coral reefs need the alkaline environment and can feel when the environment changes and when the ocean becomes to acidic for them it kills off the coral.
That is to protect Cell from external Harsh Environment
Hope this helps!
Answer:
A. Carbon dioxide gas forms because an acid and a carbonate react.
This would be transcription. You transcribe the DNA into mRNA.
