Answer:

Homologous structures

Explanation:

Homologous structures are structures (i.e skeletal elements) that come from the same common ancestor but they appear in the descendants of the ancestor with some modifications, normally due to different functions.

The wing of bats, flippers of whales or dolphins and the forelimbs of horses is a common example of homologous structures. Bats, whales and horses are vertebrates and all came from the same vertebrate common ancestor.

The common ancestor of these organisms had the bones that make up these structures, but through evolution those bones that make up the homologous structure were modified to serve different functions. They were modified for the flight in bats, for swimming in whales and for life on land in horses.

spayn [35]

Answer:

Zygote fungi do not have walls between their cells and as a result, many haploid nuclei from each hypha flow into each gametangium.

Explanation:

Zigote Fungi or zygomycota corresponds to a classification of fungi, characterized by having hyphae without septum, which is why they are called cenocitic, that is, without evident walls in their nucleus.

The hyphas contain haploid nuclei that are capable of attaching to the reproductive organ of the fungus, the gametangio. In the zygote fungi, reproduction has one sexual component, the zygospores and another asexual called sporangia. When zygospores are activated they are able to move, producing sporangia by meiosis.
