Different birds eat different foods so their beaks must be suited to be able to eat the types of food that each species needs
A because a physical change , changes the appearance. the multiple choice question is A.
Answer:
The proteins are expressed differently in each cell.
Explanation:
<u>The correct answer would be that the proteins are expressed differently in each cell. </u>
The regulation of gene expression is primarily responsible for differential functions of the same DNA sequence. Multiple proteins are formed from the same DNA sequence but only the required ones are specifically expressed depending on the cell.
<em>In other words, in the blood cells, the protein is expressed for performing blood-specific functions while it is expressed for performing skin-specific functions in the skin.</em>

Recombination is the method by which organisms can randomly assort their genotypes amongst each other to create offspring with a different haplotype than either of its parents. This can be done by either copying sequences from one homologous chromosome to another (no physical exchange) or crossing over (physical exchange.
Crossing over is a mechanism in eukaryotes by which recombination can occur, in which the two homologous chromosomes contributed by both parents literally cross over and break at certain points to exchange certain sections of the chromosomes amongst each together.
Self fertilizing organisms typically do not produce offspring that are genetically identical. However, this has an inbreeding effect on its offspring, since it is recombining from the same genotype and so has a higher chance of producing homozygous offspring. This is very detrimental for mammals and some eukaryotes, but in some other organisms such as bacteria, homozygosity is typically not an issue.
