Front

A student noticed that the freshwater plant, Elodea, produced bubbles when placed in direct light. What could the student most likely conclude?

Front

Plant cells are able to produce their own food. This process happens in which structure? Options: cell wall, chloroplast, mitochondrion, vacuole

Back

chloroplast

Front

How can cells from the same organism have different shapes and functions?

Back

During differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.

Front

Why are animals considered heterotrophic?

Back

Front

What carries the instructions for making amino acids in a protein?

Back

the sequence of nitrogen bases on the mRNA

Front

How are mitosis and meiosis similar?

Back

Both require DNA replication.
