Asap! will give brainlest! students places equal amounts of bacteria on fifteen identical agar plates containing the same amounts and types of nutrients. five of the plater were kept at 0°c, five were kept at 45°c, and five were kept at 22°c (room temperature). which of the following was probably the hypothesis for this experiment? a) the growth of bacteria increases as temperature increases. b) the type of nutrient causes bacteria to grow faster at higher temperatures. c) the size of plates determines the temperature of the bacteria. d) the temperature of bacteria is determined by the bacteria' growth

How can scientists test their ideas about the origin of the universe if they can't physically interact with or study?

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
