This body system eliminates waste products.

What is the excretory system?

100

This structure serves as the cell’s control center.

What is the nucleus?

100

Along with adenine, cytosine, and guanine, this base forms DNA.

What is thymine?

100

This Austrian monk is known as the Father of Genetics.

Who is Gregor Mendel?

100

This type of cell division creates gametes with half the chromosome number.

What is meiosis?

100

A change in genetic information is called this.

What is a mutation?

200

Gas exchange occurs in these tiny lung air sacs.

What are alveoli?

200

This jellylike fluid fills the cell interior.

What is cytoplasm?

200

RNA contains this nitrogen base not found in DNA.

What is uracil?

200

Different forms of the same gene are called these.

What are alleles?

200

Crossing GG and gg pea plants produces offspring with this genotype and color.

What are Gg and green pods? 

200

A person’s actual genetic makeup for a trait is called this.

What is genotype?

300

This transparent eye structure is located at the front of the eye.

What is the cornea?

300

This organelle is known as the cell’s powerhouse.

What is the mitochondrion?

300

This process creates an RNA copy from DNA.

What is transcription?

300

This Mendelian law states that dominant traits appear in offspring.

What is the law of dominance?

300

Mendel’s law stating that alleles separate during gamete formation is this law.

What is the law of segregation?

300

Lentils displaying both spotted and dotted seed patterns demonstrate this inheritance pattern.

What is codominance?

400

The pineal gland produces this sleep-related hormone.

What is melatonin?

400

This organelle manufactures proteins.

What is the ribosome?

400

This sequence of three nucleotides codes for one amino acid.

What is a codon?

400

Cells with half the normal chromosome number are described by this term.

What is haploid?

400

The ABO blood group demonstrates this type of inheritance.

What is multiple-allele inheritance?

400

Genes that do not assort independently demonstrate this.

What is linkage?

500

The brain and spinal cord form this nervous system.

What is the central nervous system?

500

Selective diffusion across a membrane is called this.

What is osmosis?

500

Noncoding sections of DNA within genes are called these.

What are introns?

500

Traits controlled by many gene pairs demonstrate this inheritance pattern.

What is polygenic inheritance?

500

Genes on the same chromosome can still inherit independently through this process.

What is recombination?

500

Siamese cats demonstrating one gene affecting multiple traits show this phenomenon.

What is pleiotropy?
