Unit 10 Review: Ecosystem Stability and Change and RRL's

Front

What is the lysogenic cycle in viral replication?

Back

The lysogenic cycle is a viral replication process where the virus's DNA integrates into the host cell's DNA and remains dormant until activated.

Front

How do viruses differ from cells?

Back

Viruses lack the structures necessary for metabolism and reproduction without a host.

Front

What happens in the lytic cycle after the viral DNA enters the host cell?

Back

The virus uses the host cell's machinery to make copies of itself and release new viruses.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem.

Front

How does higher biodiversity affect ecosystem resilience?

Back

Higher biodiversity increases the resilience of ecosystems, helping them recover from environmental changes.

Front

What is mutualism?

Back

Mutualism is a type of symbiotic relationship where both species benefit from the interaction.

Front

Give an example of mutualism.

Back

Bees and flowering plants, where bees pollinate the plants while obtaining nectar.

Front

What is the role of a virus in a host cell during the lytic cycle?

Back

In the lytic cycle, the virus takes over the host cell's machinery to replicate and produce new viruses.

Front

What is the difference between the lytic and lysogenic cycles?

Back

The lytic cycle results in the immediate destruction of the host cell, while the lysogenic cycle integrates into the host's DNA and can remain dormant.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment.
