Cell Division & Reproduction
These are the three main reasons why cells divide.
What are reproduction, growth, and repair?
These tiny blood vessels allow the exchange of gases and nutrients.
What are capillaries?
A mating cross where two organisms are both heterozygous for two different traits
What is a dihybrid cross?
Known as the father of genetics, he experimented with pea plants.
Who is Gregor Mendel?
These macromolecules are made of carbon, hydrogen, and oxygen.
What are carbohydrates?
This is the longest stage of the cell cycle, where the cell grows and carries out its assigned function.
What is interphase?
This substance emulsifies fats in the small intestine.
What is bile?
This occurs when one allele is not completely dominant over another, resulting in a blended phenotype.
What is incomplete dominance?
A pair of chromosomes that are similar in size, shape, and genetic function.
What are homologous chromosomes?
This structure is described as a “fluid mosaic.”
What is the cell membrane?
This cell form only has one set of unpaired chromosomes.
What is a haploid cell?
These structures absorb lipids in the small intestine.
What are lacteals?
Adenine pairs with this nitrogenous base in DNA.
What is thymine?
This term refers to an organism who inherited the same alleles from each biological parent.
What is homozygous?
This type of transport moves substances from low to high concentration using energy.
What is active transport?
This type of cell division produces four non-identical daughter cells.
What is meiosis?
This muscular valve controls the passage of chyme into the small intestine.
What is the pyloric sphincter?
The probability of two heterozygous parents having a child with a recessive disorder.
What is 25%?
This process occurs in prophase I when homologous chromosomes exchange genetic material.
What is crossing over?
This structure stores genetic information in a double-helix shape.
What is DNA?
This error occurs when homologous chromosomes fail to separate during meiosis.
What is non-disjunction?
The iron-rich protein that carries oxygen in red blood cells.
What is hemoglobin?
The genotypes of a woman with type A blood and a man with type B blood who have a child with type O blood.
What are IAi and IBi?
This tool is used in genetic experiments to predict the possible genotypes and phenotypes of offspring based on parent alleles.
What is a Punnett square?
This process adds a phosphate group to ADP to form ATP.
What is phosphorylation?
