Which structures are found in all prokaryotic cells?

What type of cell is described below?

*contains mitochondria

*contains ribosomes

*reproduces by meiosis

*performs photosynthesis

Four of the six kingdoms are comprised of organisms that contain eukaryotic cells. Which of the following structures in a cell would not be evidence that the cell is eukaryotic?

Scientists think eukaryotes may have evolved from an endosymbiotic relationship between prokaryotes and mitochondria and host parasitic cells. One piece of evidence that supports this endosymbiosis theory is that mitochondria have their own system of transcription and translation that more closely resembles protein synthesis in prokarytoies than eukaryotes. Upon Evaluation of this information, which of the following statements is most likely true?

Based on cell size and complexity, prokaryotic cells cells would be expected to

A scientist observes two cells. Cell 1 and Cell 2 both contain DNA (genetic material) and ribosomes. However, Cell 1 contains a nucleus and other membrane-bound organelles, which Cell 2 does not. What is the correct classification for each of the cells?

What evidence best supports the Endosymbiotic Theory, which states that current cell organelles like mitochondria and chloroplasts were once prokaryotic cells consumed by other prokaryotic cells?

Viruses store their DNA or RNA in the...

1. Virus injects DNA or RNA into the cell
2. Viral genes transcribe and translate by the host cell's machinery
3. An infected cell synthesizes more viral protein and genetic material instead of its usual products
4. Viruses burst (lyse) from host cells and kill the cell
5. Virus connects to a receptor on the cell's surface
6. New viruses infect other cells and create more viruses
7. Virus genomes and protein cotas self-assemble

Re-sequence the steps in teh chart to reflect the correct order of the virus reproduction process.

Which of the following illnesses is caused by a virus?

A retrovirus gets its name from teh fact that, when it infects a cell, a retrovirus-

Viruses and cells are different in many ways. In which of these ways are viruses and cells most similar?

Viruses are host cells to-

Which of the following is effective in reducing the number of viral infections?

When HIV initially infects a cell, the viral RNA is converted into DNA and then the newly formed DNA is integrated into the host cell's own DNA During this time, the infected person might feel flu-like symptoms. After the symptoms go away, the infected person may not have any other symptoms of HIV for many years.

The integration process that genetic information from HIV undergoes is part of the-
