Answer:
I) Presence of nuclear envelope
II) Presence of membrane-bounded organelles
Explanation:
Unlike prokaryotic cells, eukaryotic cells possesses nuclear membrane and membrane-bound organelles. As a result, they undergo mitosis and meiosis.
Examples of organisms with Prokaryotic cell are bacteria, cyanobacteria
Examples of organisms with eukaryotic cells are green plants, fruitfly etc
I would say commensalism since one organism benefits (the seeds) and the other other is neither benefited nor harmed
Well, you failed to mention which one is the recessive trait in this instance. But, let’s say red hair is recessive, denoted by r and brown hair is dominant denoted by R. Mom is rr and dad is RR. All children are going to be Rr and so heterozygous. They will all carry the trait for red hair but will express brown hair themselves, so 0% probability of having a child with red hair from the initial parents
