Dissolved oxygen in water Inorganic pollutants in water Oxygen required by microorganisms to decompose organic matter Total dissolved solids in water
Q9. The concept of maternal effect genes in Drosophila, such as bicoid and nanos, is fundamental to early embryonic patterning. Bicoid protein, a transcription factor, is responsible for specifying the anterior half of the embryo by activating specific downstream genes. Which of the following is a direct target of bicoid in anterior patterning?

Caudal Hunchback Toll Serate

Q18. The concept of 'keystone species' highlights species that have a disproportionately large impact on their ecosystem's structure and function relative to their abundance. Removal of a keystone species often leads to:

A minor alteration in ecosystem composition A significant shift in species diversity and community structure Increased stability and resilience of the ecosystem An increase in the population sizes of many other species
