Dive Biology Terms Lesson 27

element – a pure substance that can't be broken down into other substances by physical or chemical changes.
Lipids or fats – Like carbohydrates made of CHO but a different ratio of H: O
Eg. Beef fat = C57 H11 O6 Note how many carbon atoms there are . 57 !!!!
The more Carbon atoms a molecule has the more energy rich it is. Fats are solid at room temp. Oils are liquid at room temp.
Foods high in lipids are oil, butter, cheese, nuts, olives.
Succession – Orderly, natural changes, and species replacements that take place in communities of an ecosystem over time.
absorption – The uptake of small nutrient molecules by an organism's own body; the third main stage of food processing, following digestion.
artery – A vessel that carries blood away from the heart to other parts of the body.
autotroph – is an organism that collects energy from sunlight or inorganic substances to produce food
Characteristics of animal cells:
-Contains centrioles
-Nucleus in the center
-More rounded shape
-Many small vesicles – Characteristics of animal cells:
-Contains _____________
-__________ in the _________
-More _________ shape
-Many small __________
density dependent limiting factor – factors that affect a population more when population density is higher (when it is more crowded); ex. Competition, predator/prey relationship, and disease/parasites.
cardiac muscle – Involuntary muscle tissue found in the heart.
RNA stands for what? – Ribonucleic Acid
Surgical repair using skin from others
Biosynthesis – The process by which living organisms produce larger molecules from smaller molecules.
Endoplasm – The dense cytoplasm found in the interior of many cells
Chromosome – Structure containing hereditary material; composed of DNA that codes for all characteristics of an organism.
social learning – Learning through observing others.
malaria – Caused by a type of parasitic protozoan, called a Sporozoan, that infects the liver and blood.
7.1.4 – Distinguish between unique or single-copy genes and highly repetitive sequences in nuclear DNA. – The 'gene coding region' (about 1.5 % of our DNA) codes for a polypeptide (around 25, 000 proteins).
Around 3% of the human genome is regulatory coding for genetic switches which control development.
The non-coding region function remains unclear but can be as much as 5-45% of the total genome.
These regions are often made of highly repetitive sequences of bases each some 5-300 bases long. These are referred to as satellite regions. These are the parts of DNA used in finger print technologies.
Microclimate – Environmental conditions spreading of a small distance
Surgicаl repаir using skin frоm оthers
Arteries – Blood vessels that carry blood away from the heart
Unsaturated fats has ______ bonds – double bonds
Speciation – A process typically caused by the genetic isolation from a main population resulting in a new genetically distinct species.
What do bacterial cells not have that other cells do? – – Mitochondria
– A nucleus
– Chloroplasts
The bond that holds two amino acids together – Peptide bond
