Front

What are genetically modified (GM) crops?

Back

Crops that have been altered using genetic engineering techniques to introduce new traits, such as resistance to pests or herbicides.

Front

What is the significance of herbicide or pesticide production in GM crops?

Back

Many GM crops produce their own herbicides or pesticides, which reduces the need for external chemical applications, potentially lowering environmental impact.

Front

What is the role of filaments and anthers in a flower?

Back

Filaments support the anthers, which produce pollen, the male gametes necessary for fertilization.

Front

Can a flower function without its filaments and anthers?

Back

Yes, if pollen from another plant is transferred to the stigma by a pollinator, fertilization can still occur.

Front

What is adaptive radiation in mammals?

Back

The rapid evolution of diverse species from a common ancestor, often following a significant environmental change or extinction event.

Front

What caused the adaptive radiation of mammals after the dinosaurs?

Back

A mass extinction event that eliminated dinosaurs and many other species, creating new ecological niches for mammals to occupy.

Front

What is nitrogen fixation?

Back

The process of converting atmospheric nitrogen into ammonia, making it available for use by living organisms.

Front

Why is nitrogen fixation important for ecosystems?

Back

It allows nitrogen, an essential nutrient for plants, to enter the food web, supporting plant growth and, consequently, the entire ecosystem.

Front

What is the role of transfer RNA (tRNA) in protein synthesis?

Back

tRNA carries amino acids to the ribosome and helps assemble them into proteins according to the sequence specified by mRNA.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, synthesizing proteins by linking amino acids in the order specified by mRNA.
