Random Biology
The concept that organisms who are the best suited to their environment will be the most successful
Natural selection
These building blocks of proteins.
Amino acids
Which organisms have the most available energy in a food pyramid?
Producers
How much energy (ATP) is produced after aerobic cellular respiration is complete?
36
The legs of crocodiles and cats have similar bone structures and develop in a similar way which indicates a common ancestor. What type of structures are the leg bones?
Homologous structures
The grouping of cells that contain DNA, cytoplasm, ribosomes, and a cell membrane, but no nucleus or any other membrane-bound organelles.
Prokaryote or prokaryotic cell
Enzymes
A students observes a cell where the chromosomes have already been pulled apart by spindle fibers. These final step whereby the cells officially splits into 2 cells.
Cytokinesis
A biomolecule that serves as a quick (short-term) source of energy?
Carbohydrates
The outward physical appearance of a certain genotype is called the ______________.
Phenotype
This RNA is transcribed from a section of DNA and later leaves the nucleus in order to be translated into an amino acid chain during protein synthesis.
mRNA
movement of ions, and molecules across cell membranes without the need for energy input from higher concentration to lower concentration.
Passive transport
Adenine always pairs with ______________.
Thymine
The stage in meiosis 1 where crossing over occurs to create genetically different chromosomes from the originals and where centrioles produce spindle fibers.
Prophase 1
How much energy is passed form trophic level to trophic level?
10%
Organs/parts many animals still have but are no longer used like the hip bone in a whale.
Vestigial structures
This process produces four genetically unique cells, each with half the number of chromosomes as in the parent. This process forms gametes (eggs & sperm).
meiosis
The type of bond that holds nitrogenous base pairs like A & T and G & C together in DNA is called a ____________ bond.
Hydrogen
Anaerobic respiration such as lactic acid and alcoholic fermentation both result because there is no __________ available.
Oxygen
An organism that contains chloroplasts, 1 large water vacuole and a cell wall is likely which type of organism?
Plant
The process by which water moves through the cell membrane to balance out a high concentration of solutes.
Osmosis
6CO2 + 6H2O + Sun —> C6H12O6 + 6O2
What is this the formula for?
The formula for photosynthesis
When both alleles are present they will mix to create a new phenotype/trait. For example, a flower with a red allele and a white allele will show a pink phenotype.
Incomplete dominance
__________________ succession occurs when growth of organisms starts with soil being present.
Secondary succession
Fertilization of an egg by a sperm, which are scientifically each referred to as _____________, results in the formation of a ____________.
Gametes, zygote
