Front

What is a challenge in organizing the diversity of life into a phylogenetic tree?

Back

Analogy from convergent evolution.

Front

What type of bonds/linkages are formed between the fatty acid tails and the glycerol backbone in triglycerides?

Back

Ester bonds.

Front

What is the relationship between community diversity and stability?

Back

Communities with high diversity are more stable.

Front

How is a ribosome classified?

Back

As a ribozyme.

Front

What is the process called when ammonium (NH4+) is oxidized into nitrite (NO2-) and then nitrate (NO3-)?

Back

Nitrification.

Front

What is convergent evolution?

Back

The process where organisms from different evolutionary backgrounds develop similar traits.

Front

What are triglycerides composed of?

Back

Three fatty acids and one glycerol molecule.

Front

Why is high biodiversity important for ecosystems?

Back

It enhances ecosystem stability and resilience.

Front

What is the function of ribozymes?

Back

They catalyze biochemical reactions, similar to enzymes.

Front

What role does nitrification play in the nitrogen cycle?

Back

It converts ammonium into nitrite and then nitrate, making nitrogen available for plants.
