Activity In this activity, you'll use a simulation to learn about chemical reactions between atoms and molecules. Get started by
following these steps:
1. Go to the simulation Balancing Chemical Equations e.
2. Click the simulation and select the introduction. Balance the three equations using the balance scale and graph tools.
3. When you've finished all three equations, go to the game and select level 2. Complete all five challenges.
Now use what you learned from the simulation to answer the following questions.
Part A
Based on your experience in the simulation, what do the numbers 3 and 4 refer to in 3NH4?

Dr. kaylan is an ecologist who studies bird behavior. she sets up an experiment to test which type of food crows are most likely to eat when given a choice between walnuts, corn, and sunflower seeds. to perform her experiment, dr. kaylan places three food bins in an area frequented by cows. each bin contains one of the three food types. then, she measures how much of each food type is eaten every day for a month and summarizes the results of her experiment in the pie chart below. based on her results, dr. kaylan concludes that crows choose to eat corn more frequently than other food sources because it has a higher nutritional value. what is a reasonable alternate conclusion that can be drawn from dr. kaylan's data

What are simmilarities and differences between anaerobic respiration in animal and yeast cells? would prefer to get simmilarities as i already got some differences. you!

45 points how are people today being protected from tsunamis? earthquake data is analyzed to detemrine if a tsunami is likely, and if so, warnings are sent out. areas in tsunami risk zones are no longer heavily populated. radar is used to measure wave heights regularly. meteorologists study the winds to determine if wave heights will be large.
