In a population of desert plants, the timing of their blooming varies greatly. Some bloom early in the morning, others at mid-day, and others after dark. What environmental pressure might be an advantage for those plants that bloom after dark?

• there is an increase in the population of nocturnal pollinators

• there is a decrease in the strength of solar radiation

• there is an increase in herbivores that forage at night

• there is a decrease in water for root absorption

Xylem is a plant tissue made up of elongated cells stacked end to end the length of the plant’s stem. Which function is xylem specifically adapted to perform in plants?

• help prevent water loss

• exchange gases with the atmosphere

• capture sunlight for photosynthesis

• transport water from roots to leaves

Mountain lions are large cats and the top predator in their habitat. A population of mountain lions may vary in several characteristics. If a prey becomes scarce, competition between mountain lions for food will increase. Which variation would provide an advantage to the individuals that possessed it?

• short fur

• long legs

• abundant whiskers
