Hypothesis: If Plant Food X is used on a tomato plant, then production rate will increase.
experiment: Gather 2 tomato plants of the same height and age. Make two groups, a control group (a tomato plant without use of fertilizer) and an experimental group (a tomato plant with using Plant Food X).
For one week, give each plant the same amount of water, humidity, sunlight, and air temperature. after a week measure the height and number of tomatoes produced. gather the info in a table and compare to hypothesis after one week.
The given blank can be filled with selecting.
It has been shown by Belyaev and Trut that foxes can be domesticated, over the time of various generations, by selecting and mating animals with certain traits, like responses to feeding, handling, and others.
A sustained multi-generational association in which one group of species presumes a substantial extent of effect over the care and reproduction of another group to secure a more predictable supply of resources from that latter group is known as domestication.
