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.
Answer:
1. adaption
Explanation:
Salmon have special adaptation behavior that allows them to live in both freshwater and saline water during their lives.
<u>Salmons are born in freshwater where they spend few months and then move to saline water. For laying eggs, they again move to freshwater because eggs are unable to survive in saline water due to a process known as osmoregulation.</u>
Moving from freshwater to ocean water, salmon adapt according to the environment for their survival.
Hence, the correct answer is "1. adaption"
The head at the top, the tail is just for getting to the egg
