One experiment that we could use to test the way in which fruit fly populations grow is to enclose a set amount inside a container with a food source and measure the population growth daily, then repeat this many times.
In order to test the way in which the fly population grows, we need an experiment that will allow us to gather data at set intervals. To do this we can create an experiment in which we set up multiple enclosures, each with a set amount of flies and one banana. Then measure the population on a <u>day-to-day</u> interval.
By performing the experiment with multiple enclosures, we can not only confirm that the results are accurate by having tested it many times, but we can also take the opportunity to test the effects of the food supply on population growth by adding more bananas and seeing if the population will increase at a different rate than the other enclosures.
Once a set number of days have passed, and we have the data corresponding to the population size each day, we can proceed to graph the data. Once graphed, we can analyze the data shown in order to observe whether the population is growing logistically or exponentially.

Answer: D. helps in digestion
Explanation: Gastric juice in the stomach contains HCL which creates an acidic condition(pH1.5-2.0) which is optimal for the action of enzymes in the stomach. HCL stops the activity of salivary amylase & helps to kill bacteria in food. It doesn’t help in digestion cuz it is not an enzyme.
Ancient bacteria or archaebacteria, are classified in the domain Archaea.
Answer:
I believe the one with 2 cups of water will be saltier
Explanation:
When you change the fractions to a common denominator, which is 12, you see the recipe with 1 cup should be half of the recipe with 2 cups. But the one with 2 cups is more than double the recipe with 1 cup.
