Biology 106 Chap1 Flashcards
A community plus physical environment
Ecosystem
Ecosystem
Is the community plus the physical environment
Biosphere
It’s a zone or region in the earth crust where every living things live.
Mentabolism
Is a chemical reaction that occurs in a cell
What are the characteristics of life
Memonics : ARRRA H
Are organized
Requires energy &material
Reproduce and develop
Response to stimuli
Are homeostasis
Have capacity to adapt
What do organizations of life begins with
Atom
What makes up molecules
What makes of a cell
What makes a tissue
What makes a organ
The combination of two atoms
The combination of molecules
Combination of cells
Combination of tissues
How is the biosphere organized
Atoms come together to form molecules then cells - tissue - organ-organism-population-community- the ecosystem ( the physical +the community)
Atom
Is the smallest unit of an element contains the proton electron and neutron
Cell
Is the structural and functional unit of all living things
Tissue
A group of cell with common structure and function
Genes
They are genetic information passed to the next generation in the process called reproduction .
Every organism is characterized by their genes.
Isotopes differs in their?
Neutron
Isotopes differs in their?
Neutron
H2CO3/ NAHCO3 is a buffer system in the body . What effect will the addition of an acid have on the Ph of a solution that is buffered?
The Ph will not change
Hydrogen bonds are formed as a result of ?
Polar covalent bond
Carbohydrates is made of
Carbon
Hydrogen
Oxygen
Simple carbohydrates (monosaccharides)
It’s is a monomer , eg glucose use for the process of photosynthesis
Complex carbohydrates
Long term storage of energy
Polysaccharides example Starch
Polymer starch ( rice , potatoes, corn , wheat)
Cellulose
Glucose polymer,
Offer plant support, responsible for cell wall, energy storage,
Food source for plant bulbs&seed
Glycogen in animal
Stored in liver
Homeostasis
Is a state of maintaining biological balance internally
