When Mendel performed his experiments, only one trait appeared in the F1 generation, (in this case, round peas) and the other tr

bearhunter [10]

Answer:

See the answer below

Explanation:

The explanation I would give to the phenomenon is that the round trait in peas completely covers or nullify the wrinkled trait when they are together. In order words, whenever a single the allele of both trait come together to form a new trait, the round trait allele dominates and mask the expression of the allele of the wrinkled trait.

This is what Mendel explained and dominance/recessive effects. The round trait was dominant over the wrinkled trait while the wrinkled trait was said to be recessive and can only be expressed when alone.

Scenario: You are a research scientist and are working with eukaryotic cells obtained from a newly discovered organism, Oviductu

Minchanka [31]

Answer:

Based on this information you come to the conclusion that you have been able to identify in these cells the structure of microfilaments or actin filaments.
Oviductus oblatus are indeed eukaryotic cells

Explanation:

In eukaryotic cells, the cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a polymer of proteinic subunits united by weak, not covalent connections.

The microfilaments are the thinnest of the three structures. They have a diameter of 7 nanometers and are composed of many proteinic monomers united. This monomeric protein is called actin. Many monomers get combined to form a structure that assembles a double helix.

Due to the fact that these microfilaments are made of actin monomers, they are also known as actin filaments.

Actin filaments have directionality which means that their extremes have different structures.

In eukaryotic cells, genes that codify for actin microfilaments are highly conserved in all organisms, which is why they are often used as molecular markers for different studies.
