Bioelements
This type of bioelement includes C, H, O, N, P, and S.
Primary bioelements
Biomolecule that provides immediate energy for cells.
carbohydrates
Function that allows organisms to maintain balance and respond to stimuli.
regulation
Primary bioelement found in all organic molecules.
carbon
Bioelements that appear in smaller quantities but are essential for nerve impulses and osmotic balance.
Secondary bioelements
These biomolecules store long-term energy and form cell membranes.
lipids
Function that ensures the continuity of species.
reproduction
two types of nutrition
Autotrophic and heterotrophic
These bioelements are required in very small amounts, such as Fe, Zn, and Cu.
Trace elements
The type of biomolecule made of amino acids.
Proteins
Explain the difference between growth and development.
Growth = increase in size/number of cells; Development = changes in form and function.
Trace element required to form hemoglobin.
iron
Name two functions of calcium in living organisms.
-bone formation
-muscle contraction?
-blood clotting
Name the two types of nucleic acids.
DNA and RNA
Type of reproduction that involves one parent and produces identical offspring.
asexual reproduction
Explain how the three biological functions (nutrition, relation, and reproduction) work together to maintain life in an organism.
Nutrition provides energy and materials; relation allows the organism to respond and adapt to stimuli; reproduction ensures species continuity.
Explain the difference between primary and secondary bioelements in terms of structure and abundance.
Primary form organic molecules; secondary regulate metabolism and appear in lower amounts
Explain why nucleic acids are essential for heredity and protein synthesis.
DNA stores information; RNA transcribes/translates it into proteins.
Name one advantage and one disadvantage of sexual reproduction.
Advantage: genetic diversity. Disadvantage: requires more energy/time.
Name one role of secondary bioelements in living organisms.
Regulating nerve impulses, osmotic balance, muscle contraction, etc.
