A researcher is studying a sample of cells taken from an organism found in the Arctic Ocean. The researcher makes the following observations about the cells: They do not make their own food. They each have a nucleus. They do not have cell walls. Based on these observations, the organism should be classified as which of the following?

The speed of  sound:   sound travels  at different speeds depending on what it istraveling through. of the three mediums (gas, liquid, and solid)  sound waves travel the slowest through  gases, faster  through  liquids, and fastest  through  solids.

The rate that would change would be the  searching efficiency/attack rate. there are only two other rates in this model: the  growth rate of prey, and the  predator or consumer mortality rate.the  searching efficiency/attack rate is what indicates how effectively can a predator capture its prey whether in the searching process or actual capturing/attacking process.
