u/1
Biology
The study of life and living organisms.
Protons
Have a positive charge. Found in the nucleus.
Homozygous
An organism with two of the same alleles for a particular trait.
u/1 biosphere
layer of earth that supports life.
u/3Structure of DNA
Adenine and Thymine always bond together
Cytosine and Guanine always bond together
Notice this in the diagram on the right.
A goes with T.
C goes with G.
Notice the image on the right.
Organism
Anything that is or was alive.
Neutrons
Have a neutral charge. Found in the nucleus.
Heterozygous
An organism with different alleles for a particular trait.
u/1Ecological Succession
the process by which the mix of species and habitat in an area changes over time.
Biotic Factors
The living factors in an organism’s environment.
Electrons
have a negative charge. Found outside the nucleus.
Phenotype
The observable characteristic or outward expression of an allele pair
u/2Mitochondria
"powerhouses," that generate most of the cell's energy (ATP) by converting food into usable fuel through cellular respiration,
Abiotic Factors
The non-living factors in an organism’s environment.
Isotopes
Atoms of the same element that have a different number of neutrons.
Genotype
An organism’s allele pairs.
u/2Ribosome
essential cellular machines made of RNA and protein, found in all cells, that synthesize proteins by translating messenger RNA (mRNA) sequences into chains of amino acids (polypeptides)
Limiting Factors
Anything in the environment that keeps a population’s size in check, preventing it from growing forever.
Macromolecules
Large molecule formed by joining smaller organic molecules together.
Incomplete dominance:
heterozygous (Xx) phenotype is a blend between those of the two homozygous (XX and xx) parents
u/3Leading Strand
The continuously synthesized strand
