cell biology
This structure controls what exits and enters the cells
What is....The Cell Membrane
This molecule is the main source of usable cellular energy
what is.....ATP
different forms of the same gene are called this...
what is...alleles
This molecule carriers genetic instructions from DNA to the ribosomes
what is....mRNA
This is the selective force in antibiotic resistance
what is....antibiotics
Plant cells contain this organelle used for photosynthesis
What is....chloroplasts
Enzymes speed up reactions by lowering this?
what is....activation energy
This term means having two identical alleles..
This molecule carriers amino acids during translation..
what is....tRNA
A large zone of inhibition means this...
what is....the antibiotic is effective against the bacteria
Water moves out of the cell in what type of solution?
what is....hypertonic
This happens to enzymes at extremely high temperatures
what is....denatures
These seperate during meiosis 1
homologous chromosomes
This is the site of translation
what is....ribosomes
this process explains how populations change over generations
what is...natural selection or theory of evolution
This process is the movement of water through a membrane from high to low concentration
what is....osmosis
What are the reactants of cellular respiration?
Oxygen and Sugar (Glucose)
These seperate during meiosis 2....
what is....sister chromatids
This process copies DNA into mRNA
what is...transcription
Why does antibiotic resistant become more common after antibiotic use
what is....resistant bacteria survive and reproduce while non-resistant bacteria die
Explain two differences between prokaryotic and eukaryotic cells
what is....prokaryotic cells contain no membrane bound organelles, eukaryotic cells contain a nucleus, ER, and mitochondria
Explain how exercise affects heart rate and breathing rate.
what is...increases both of them to excrete waste products, like carbon dioxide, and in terms of heart rate it pushes more oxygen and nutrients throughout the body.
Explain the difference between homologous chromosomes and sister chromatids.
what is....homologous chromosomes are one from dad and one from mom and can have different alleles. Sister chromatids are from one parents and are identical.
Explain the difference between translation and transcription
why does combination drug therapy help slow does HIV resistance
what is....it is unlikely that the virus has mutations resistant to multiple drugs at once
