Cells
These are expressed in either the heterozygous or homozygous condition
What are Dominant Alleles?
The common features shared by living organisms
What are characteristics of life?
The pathway along which energy is transferred in an ecosystem
What is a food chain?
Different forms of the same gene. They occupy the same position(locus) on homologous chromosomes.
What are alleles?
When cell membranes allow the passage of some materials but not others.
What is selective permeability?
These are composed of DNA and protein, consisting of coding regions and non-coding regions.
What are chromosomes?
Removal of waste products of metabolism.
What is excretion?
Carnivores that feed on secondary consumers.
What are tertiary consumers?
Agents that cause mutations
What are mutagens?
The conversion smaller molecules into larger ones. (Using energy)
What is anabolic reaction?
the process of growing bacteria in a bioreactor by starting with a fixed amount of nutrients and emptying the contents of the vessel at the end to harvest the product.
What is Batch Processing?
The reaction of organisms to stimuli in their environment.
What is a response?
The way in which elements (Carbon and Nitrogen) are exchanged between the living and non-living components of an ecosystem
What is nutrient recycling?
The conversion of a sequence of genetic bases on mRNA into a sequence of amino acids.
What is transation?
The ammonia is converted to nitrites and then to nitrates by nitrifying bacteria.
What is nitrification?
The use of living cells, their components or enzymes to make useful product or destroy harmful waste.
What is Bioprocessing?
This is the Sum of all the chemical reactions in an organism.
What is metabolism?
These are based on numbers of organisms at each trophic level in a food chain.
What are pyramids of numbers?
Copying of a sequence of genetic bases from DNA onto mRNA. (Making mRNA using DNA template)
What is Transcription?
Lives on dead organisms
What are saprophytes?
This is a sequence of three DNA or RNA nucleotides in a gene that correspond to a specific amino acid (or a stop signal) during protein synthesis.
What is a Codon?
Living things that arise from other living things of the same type (Biogenesis)
What is the continuity of life?
All plants and animals sharing the resources of a particular habitat
What is a community?
The process whereby genetic information, encoded in a gene, is transferred to its functional product.
What is Gene expression?
This has a higher concentration of solutes and thus a lower concentration of water than another solution.
What is a hypertonic solution?
