Reproduction
A type of cell division resulting in two genetically identical daughter cells, used for growth and tissue repair.
What is "mitosis"?
The genetic information inside the nucleus of an organism’s cells that is inherited from the parents. The information can be used as a code to make proteins.
What is "DNA"?
A specific characteristic of an individual that has been inherited from parents. Can be physical or behavioural.
What is a "trait"?
The body's ability to maintain a stable internal environment despite external changes.
What is "homeostasis"?
Single-celled microorganisms found almost everywhere on Earth; Some can cause infections and make us sick, but many are harmless and even beneficial.
What are "bacteria"?
A specialized cell division that reduces the chromosome number by half, creating four genetically diverse gametes.
What is "meiosis"?
A section of the chromosome/DNA inherited from each parent; the basic unit of heredity.
What is a "gene"?
The amount or number of differences in the traits of a population of species.
What is "genetic variation"?
The body system responsible for the exchange of carbon dioxide and oxygen in the human body. It includes organs such as the nose, trachea, bronchi, and lungs.
What is the "respiratory system"?
Variations and traits in a population that can be passed from one generation to the next - from parents to offspring.
What is "heritable" or "inherit"?
A mature haploid (half of a full set of DNA) reproductive cell (sperm or egg) capable of uniting with another during fertilization.
What is a "gamete"?
Parts of DNA that do not code for proteins but has a regulatory function by turning a gene on or off or even speeding up or slowing down the creation of a protein.
What is a "regulatory gene" or "regulatory DNA"?
A type of DNA sequence at a given genomic location (location on a gene in DNA).
What is an "allele"?
A physiological (physical changes that happen in your body) loop (usually negative) that adjusts bodily systems to maintain homeostasis.
What is a "feedback mechanism" or "feedback loop"?
Any environmental resource, condition, or interaction that restricts the growth, abundance, or distribution of an organism or a population within an ecosystem.
What is a "limiting factor"?
Where is the "ovary"?
The building blocks (macromolecules) of DNA.
What are "nucleotides"?
Unusable byproducts (such as carbon dioxide, urea, or excess salts) generated by cellular life processes that must be excreted (gotten rid of).
What is "waste" or "metabolic waste"?
The specific ecological role and position that a species occupies within its environment. It includes the resources it uses, the interactions it has with other species, and the conditions it requires for survival and reproduction. The "job" a species has in its ecosystem.
What is "niche"?
The early stage of development before becoming a fetus; A fertilized egg starts as a zygote, then becomes a ____________ before being called a fetus.
What is an "embryo"?
A process that occurs in the ribosome of the cell which makes proteins; The process uses DNA, RNA, and amino acids to make the proteins. These proteins are used in a variety of biochemical processes and play a role in the presence or absence of the traits of an organism.
What is "protein synthesis"
Having two different alleles of a particular gene or genes. A different one from each parent.
What is "heterozygous"?
The process by which the body maintains a relatively constant core body temperature. Sweating and shivering are part of this process that regulates temperature homeostasis.
What is "thermoregulation"?
Any close and long-term biological interaction between two different species.
What is "symbiosis"?
