• lysis

• nexus

Multiple Choice

Archaea and Bacteria are

• 5 million years ago

• 3.8 billion years ago

• 4 trillion years ago

Multiple Choice

• detritus

• littorous

• scavagery

• deposition

Multiple Choice

autotrophs

• make their own energy

• consume others for energy

Multiple Choice

what is the most important primary producer on the planet?

• marine mammals

• aquatic plants

• marine diatoms

• marine eukaryotes

Multiple Choice

which organelle is used for photosynthesis?

• mitochondria

• chloroplasts

• nucleus

• Golgi apparatus

Multiple Choice

when toxins accumulate as you go up the food chain/web

• bioaugmentation

• biomagnification

• toxoplasmosis

• bioremediation

Multiple Choice

About half of the known marine diatoms are

• prokaryotic

• single celled animals

• planktonic

Multiple Choice

Each time diatoms reproduce asexually, the new cells

• are smaller than the original cell

• the same size as the original cell

• are bigger than the original cell

Diatom cell division takes place when the overlapping halves of the frustule separate, and each secretes a new, smaller half. The smaller, lower frustule of the parent cell becomes the larger frustule of a daughter cell, which then secretes a new, smaller frustule.
