Body Systems
Neurons are the primary unit of this bodily system.
What is the nervous system?
The interaction of species in an environment.
What is community ecology?
Among domain, kingdom, class, order, family, genus, and species, there is a missing taxonomic group.
What is “phylum?”
This is the branch of biology concerned with the study of genes, genetic variation, and heredity in organisms.
What is genetics?
This surrounds and supports bacterial cells?
What is a Cell Wall?
The stomach is part of this system
What is the digestive system?
A cow and sheep competing for the same food source is this type of interaction
-/- (competition)
A certain kind of land snail has a mutation causing its shell to spin in the opposite direction, and these snails cannot mate. Provide the word for the result of this phenomenon.
What is “reproductive isolation?”
An alteration or change in the nucleotide sequences of DNA.
What are mutations?
These 2 structures are found in all types of living cells.
What is Cell Membrane, Ribosome, Cytoplasm, DNA?
The central nervous system consists of the Brain and this major nerve
what is the spinal cord?
Claws and teeth of a predator are an example of this
Adaptation
Two processes that produce variation in gene pools, contributing to differences in individuals of a population.
What are “mutation” and “sexual reproduction?”
Two individuals heterozygous for the dominant trait of brown hair are having a baby. The baby has this percent chance of inheriting her grandmother's blue eyes
What is 25%?
Are Prokaryotic cells unicellular or multicellular?
What is Unicellular?
Kidneys produce urine, a component of this system
What is the excretory system?
This species is at the top of the food chain and strongly controls their community
Keystone species
The Darwin phrase often used to define evolution.
What is “descent with modification?"
A cat has black and white spotted fur. The inheritance pattern is:
What is co-dominant?
Found in both fungal and bacteria cells, these cell parts assemble amino acids into proteins.
What are Ribosomes?
Bones produce a substance that is found in this system
what is the circulatory system?
A differentiation of ecological niches that enable similar species to coexist in the same community.
Resource partitioning
Speciation occurring in populations that live in the same location.
What is “sympatric speciation?”
A woman heterozygous for brown eyes and brown hair marries a man with the same genotype. Both traits are dominant. The couple's first child will have this chance (out of 16) of having a child with blonde hair and brown eyes.
What is 3/16 or 19%?
(Always 9:3:3:1 ratio)
Bacterial plasmids are made of this.
What are Double-stranded DNA molecules?
