Answer:

The correct answer is C) selective transport through nuclear pore complexes

Explanation:

Nucleus is the place where the replication and the transcription of DNA occurs. The process of translation in eukaryotes occurs in cytoplasm therefore RNA has to come out of the nucleus.

Nuclear pore complexes are the openings in the nuclear membrane from where these molecules come out in the cytoplasm. Small RNA like tRNA directly comes out through binding directly to export receptors but large RNA like mRNA forms ribonucleoprotein particles which involves class-specific adaptor proteins for transport. So the right answer is C.

Alja [10]

For a single-celled life form that the information handed down to offspring, we would see every generation would be a carbon copy of the one single-celled life form.This is further explained below.

To find the completion we need to know more about a single-celled life

<h3>What would happen to a single-celled life form if the information handed down to offspring was always copied perfectly?</h3>

Generally, A single-celled organism, also known as a unicellular organism, is an organism made up of only one cell.

In conclusion, Every generation would be a carbon copy of the one before it.

Explanation:

Food web is defined as the interconnection between different food chains which shows how organisms from different food chains are connected with each other for food in the ecological community.

In the attached image, there are three consumers which depend on the same producer for food. Those three consumer are squirrel, robin, and field mouse feeding over plant seeds (producer) for survival.

Hence, the correct option is A.

What is the correct order for the hierarchy of biological organization from the least to the most complex? (concept 1.1)?

hjlf

Answer;

Molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem.

Explanation;

-The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

-Organisms are highly organized, coordinated structures that consist of one or more cells. Even very simple, single-celled organisms are remarkably complex: inside each cell, atoms make up molecules; these in turn make up cell organelles and other cellular inclusions.

-In multicellular organisms, similar cells form tissues. Tissues, in turn, collaborate to create organs (body structures with a distinct function). Organs work together to form organ systems.
