This is the location meisois occurs in biological female. 

What are ovaries?

100

This polysaccharide is used for energy storage in human livers. 

What is glycogen?

100

These organisms recycle nutrients in an ecosystem. 

What are decomposers?

100

Known as the powerhouse of the cell, this organelle is responsible for aerobic respiration. 

What is the mitochondria?

100

The process where organisms better adapted to their environment tend to survive and produce more offspring. 

What is natural selection?

200

This excretory organ works closely with the circulatory system to filter metabolic waste such as ammonia and salts from the blood. 

What is the kidney?

200

These are the three components to a nucleotide. 

What are ribose sugar, phosphate group, and nitrogenous base?

200

This process describes how an ecosystem recovers from a disturbance such as a wildfire or a flood. 

What is secondary succession?

200

The wobble rule states the base at this position is least important when coding for an amino acid. 

What is the third position? 

200

The process by which humans intentionally choose specific plants or animals to combine gametes based on their desirable traits

What is selective breeding?

300

These grape-like structures are responsible for gas exchange in humans. 

What are alveoli?

300

This refers to altering the shape of a protein due to unfavorable conditions like high temperature, or low pH. 

What is denature? 

300

As opposed to an food chain, which depicts energy flow through an ecosystem in a linear manner, this shows how energy flows between all organisms in an ecosystem. 

What is a food web?

300

If a protein is being secreted out of the cell, it will be synthesized at this cellular location. 

Endoplasmic reticulum 

300

The hand of a human and the wing of a bat is an example of this because while they may have the same number of bones due to their common ancestry, both limbs are structured in very different ways due to the differences in environmental pressures. 

What are homologous structures?

400

This signaling molecules is either a lipid or a protein and travels through the blood of animals. 

What is a hormone?

400

This enzyme is responsible for the dehydration synthesis reaction involving two RNA nucleotides. 

What is RNA Polymerase? 

400

This can refer to both the role a species has in an ecosystem, as well as where it is physically located in its ecosystem. 

What is a niche?

400

This refers to DNA with its histone proteins, used in Eukaryotes. 

What is chromatin?

400

The tail fins of a shark and a whale are examples of this. 

What are analogous structures?

500

The folding of the small intestines absorb more nutrients due to an increase in this. 

What is surface area?

500

When carbon dioxide mixes with water, it does this to the pH of the water. 

What is lower the pH? 

500

The presence of this type of species has a relatively huge effect on the stability of the ecosystem. 

What is a keystone species? 

500

A human cell with only 23 chromosomes is said to be this. 

What is haploid?

500

This organelle is used to track relatedness because it is passed down from mother to offspring. 

What is the mitochondria?
