Eukaryotes have a nucleus, prokaryotes do not. While you did not supply descriptions, this is one of the basic and most obvious difference.
Answer:
they will gather quantitative Data, using a thermometer and a balance.
Explanation:
This experiment is a type of quantitative research.
Quantitative Reseach:
Studies the effect of an independent variable on dependent variables by collection of quantifiable data that can be subjected to mathematical or statistical tools to draw conclusions.
The students will need a thermometer and balance to note the variation in the temperature of water in the aquarium and to measure the weight/mass of the duckweed respectively. Plotting these values against each other on a graph will give the effect of temperature on the rate of growth of the duckweed.
The heart must beat faster during exersise because by increasing the heart rate the body is able to increase cardiac output and deliver the necessary blood flow to the mucles
<span>10% rule (efficiency between trophic levels): limits how long an ecosystem's food chain can be
Predator/prey
cost benefit analysis (i.e. foraging) -- cost is risk of being eaten or
killed along the way, benefit is energy/nourishment obtained: limits
distribution of predator v. prey
Immigration/Emigration with other populations and ecosystems
Island
biogeography: size of land and distance from another
population/ecosystem (mainland): limits population size and variability
