We have evidence to support the claim that the trait of antibiotic resistance has increased in many species of bacteria since penicillin became the first commercially available antibiotic in the 1940's. Bacteria reproduce by binary fission, a form of asexual reproduction (meaning one cell reproduces identical copies of itself). All bacterial populations have the potential to undergo changes in traits; creating populations of bacteria that have a large variation in traits. Identify TWO processes that contribute to variation of traits in an actively reproducing population of bacteria. Be sure to discuss each of the following in your response:
-the relationship between nucleic acids, proteins, and traits (gene expression)
-the regulation of gene expression (methylation, acetylation, regulatory genes/proteins)
-specialization and differentiation of cells (as the result of regulated gene expression)

Which of the following requires the use of energy and the of transport proteins to move a molecule across a cell membrane?

Brepresent the dominant allele for brown fur, and b represents the allele for white fur. if two rabbits with the genotype bb reproduce, what are the possible phenotypes for their offspring

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
