Question

Flowers are derived evolutionary from modified __________________.

One grouping of gymnosperms has been particular successful in mountainous region that can get both very cold and very dry during different seasons. Which of the following can explain their success in these environments over other plants?

The thin needle-like leaves of conifers helps reduce water loss during dry months and allows snow to fall through during winter months preventing branch and trunk damage from excess snow weight

The wide broad leaves of ginkgophytes provides insulation during cold months and greater heat release during warm months

Many gymnosperms can completely dry out during the dry months and then can be restored to full health with sufficient water during wet months

All of them

Let’s say you were a multicellular photosynthetic protist living in a pond 400 million years ago and many of your neighbors began moving onto land and suggested you should come too. Which of the following would NOT be something your neighbors might say when explaining why land is so great?

Neighbor Joe says it is easier to “breathe”, there is plenty of carbon to “inhale”

Neighbor Maria says there is much more light to keep going

Neighbor Ann says it is easier to reproduce, it is easier to spread my gametes on land

All of the other answers are true advantages of life on land over life in water

Which of the following statements about Protists is false?

Protists perform both asexual and sexual reproduction

A few protists live as colonies

Protists exhibit many forms of nutrition and may be aerobic or anaerobic

Protist species live only in terrestrial environments
