1. consider your physical science textbook sitting on the floor of the classroom. a student walks by, lifts your book, and places it on your desk. the initial state is the book sitting on the floor. the middle state is the student lifting the book. the final state is the book sitting on the desk.

1a. draw system schema in the energy flow diagrams.

1b. list all the energy storage modes involved in the initial state. explain how you know they’re present. explain what will happen to the amount of each energy storage mode from the initial state to the middle state.

1c. list all the energy storage modes involved in the middle state. explain how you know they’re present. explain what will happen to the amount of each energy storage mode from the middle state to the final state.

1d. list all the energy storage modes involved in the final state. explain how you know they’re present.

1e. complete the energy flow diagram in 1a.

i do not know and i have a 100 in this class

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
