Answer:
The finches on Galapagos Islands had different beak
The beaks of the finches changed over time
The Galapagos finches had a common ancestor
Explanation: Darwin's Finches are a good example of natural selection and adaptive radiation of evolution. The different finches in Galapagos Island have emerged from a common black, seed eating, short beak finches. This is called adaptive radiation, where different species arose from a single ancestor.
Due to changes in the natural environment, food resources, some finches have a long beak. This long beaks help them to eat insects. As a result, the competition will be less and nature selects them to survive in the new environment. This is a natural selection of evolution.
Organic compounds are molecules built around the element carbon (C). Living things are made up of very large molecules. These large molecules are called macromolecules because “macro” means large; they are made by smaller molecules bonding together
Answer and Explanation:
Genomic imprinting is a phenomenon in which expression of the gene depends on whether it is inherited from the male or the female parent. Depending on how the genes are marked, the offspring expresses either the maternally-inherited or the paternally-inherited allele.
An allele can demonstrate different effects depending on whether it was inherited from the male or female parent. In male offspring only one copy of the allele is inherited, and it comes from the female parent. Only male offspring inherit the trait.
The genetic traits are inherited solely from the female parent

This study serves as a proof of concept that complete organs
can be grown from harvested stem cells and, when transplanted, achieve normal
function, the authors said, hopefully advancing the field from stem cell
transplantation for organ repair towards full organ replacement.
