What is sickle cell trait?
_______% of Earth’s water is freshwater, the rest is saltwater.
What is 2.5%
This characteristic of life maintains stable internal conditions in organisms.

What is cellular respiration?
A hypothesis is never __________________, only supported or refuted.
What is "proven"?
There are two types of mutations where a frameshift in the DNA sequence happens, where all codons after the mutation shift. This change usually has a large, and often harmful, effect on a protein. Name one of the two types of mutations.

What are experimental biases?
In this first step of DNA replication, DNA is unzipped and complementary nucleotides added to an mRNA strand.
What is transcription?
This percentage of energy is passed from one trophic level to the next.
What is 10%?
The function of this organelle is to package and ship molecules. It is often thought of as the "post office" of the cell.
What is the Golgi Apparatus?
During anaerobic respiration in animal cells, this product builds up in the cell sometimes causing muscle cramping.
What is lactic acid?
A research question is considered ________________ when it can be answered through an experiment, not just research or opinion.
What is testable?
This Amino acid, made up of three RNA sequences tells a ribosome to "start" building a strand of protein.
