What structure is found in prokaryotic cells but not eukaryotic cells?

a. a single, circular DNA chromosome found in the cytoplasm

Prokaryotic cells may also contain extrachromosomal DNA, or DNA that is not part of the chromosome. This extrachromosomal DNA is found in plasmids, which are small, circular, double-stranded DNA molecules.

What type of rock is limestone? Describe how a limestone rock is likely to change over a long period of time.
frosja888 [35]

Answer:

Explanation:

Most limestones actually start as calcium carbonate mud or shells precipitated by organisms in reefs or shallow shelf regions - the biosphere. Over time, the limestone is broken down into its chemical parts and may come back to the surface as volcanic CO2 (in the atmosphere).

Anatomy<br> Label each of the following structures or processes.
RSB [31]

Answer:

A - DNA

B - mRNA

C - nuclear pore

D - tRNA

E - ribosome

F - rRNA

Explanation:

<em>The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.</em>

The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.

Population crashes cannot happen to humans?True False?<br><br>​
Galina-37 [17]
I think false because no one knows what will happen in the future and anything is possible, although the population does increase it can still decrease by high amounts aswell, anything bad could happen any time. People may not even have money to survive but it really depends on what happens and what could happen in the future, no one really knows what will happen so this statement would be false.

Anyway have a nice day :)

Summarize the process of DNA replication in the purpose.
Slav-nsk [51]
This is the process of DNA replication :


Cells Can Replicate Their DNA Precisely. Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. ... To accomplish this, each strand of existing DNA acts as a template for replication.

hope this helps .
