Biology Pre- Test DAY 1

An amoeba, a single-celled protist, uses pseudopodia to move. Prokaryotes are not able to create pseudopodia because:

• prokaryotes are only found in warm moist environments

• prokaryotes do not produce ATP efficiently enough to move cytoplasm

• prokaryotes have no cytoskeleton to support the movement of cytoplasm

• prokaryotes are nonmobile and do not need cytoplasmic streaming

Auxins are chemicals made by plants. One auxin, idoleacetic acid (IAA) is transported down the plant's stem to encourage cell elongation and to bend toward light. The production of IAA is working with which plant system?

• Root system

• Response System

• Immune System

• Reproductive system

Biologists use a number of different classification schemes based on the complexity of cellular organization. which sequence lists levels of organization in multicellular organisms in order of increasing complexity?

• cell, organism, organ system, organ, tissue, organelle

• organelle, cell, tissue, organ, organ system, organism

• cell, organelle, tissue, organ, organ system, organism

A predator prey relationship exists between

• honeysuckle flower and a hummingbird when the flower attracts the bird

• hyena and a vulture, when the hyena eats the remains of an elephant next to a vulture

• a cuckoo and a warbler, when the cuckoo lays its eggs in the nest of the warbler

• a caterpillar and an ant, when the caterpillar feeds on the ant's larvae
