A laboratory investigation examined the growth rate of fruit flies in culture jars over time. The fruit flies were grown in an artificial
medium containing nutrients and moisture. They were enclosed in a culture jar of a defined size. Initially, there were ten fruit flies
in the experiment. The population reached 75 over the course of four weeks. However, after eight weeks, the population size
leveled off and then decreased. Survival of fruit fly larvae declined after eight weeks. Which hypotheses are supported by the
information in this scenario? Select ALL that apply?
A)
The older fruit flies were unable to reproduce
Scientific
Calc
B)
The carrying capacity was exceeded by the fly population
Food was abundant for the first four weeks of the experiment.
D)
The fruit flies were unable to survive in a laboratory setting
E)
The carrying capacity decreased when no new food was added to the
culture jars.

3points hurry! what is the relationship between biotechnology, sharkskin, and disease resistance? bioengineers have developed an artificial sharkskin that does not allow resistant bacteria to grow on it. disease-causing microbes have been genetically modified to keep them from infecting the skins of sharks. scientists have created a device that can be attached to the skins of sharks that dramatically increases their abilities to resist disease. sharkskin produces many chemicals that can be collected and used to create antibiotics.
