A group of students wants to study the effect o f temperature on bacterial growth. To get bacteria, they leave Petri dishes of nutrient agar open on a shelf. They then put the dishes in different places: an incubator (37oC), a refrigerator (10oC), and a freezer (0oC). Bacterial growth is measured by estimating the percentage of each dish covered by bacteria at the end of a 3-day growth period. a) What variables should be standardized?

Ijust need with an idea of how to write it or example.1. for this assignment you will create a developmental timeline. the timeline should include significant events, or possible future significant events, from your entire life—from womb to tomb. you are encouraged to personalize your timeline with pictures, etc. for each incident or event that you list, you need to relate it to a concept developed by piaget, kohlberg, or erikson. for example, if one of your events is, “i said my first word, ball,” and you have this on your timeline at 15 months, you also need to say, “piaget’s preoperational stage.” along with each event you discuss, provide a brief description of its significance. score
