the diagram below shows the structure of an animal cell.
what is structure 2, and how does it sustain life?

a structure 2 is the cytoplasm, which contains organelles and is the site of many cell processes.

b structure 2 is the cell membrane, which controls what enters and leaves the cell.

c structure 2 is a chloroplast, which is the site of photosynthesis.

d structure 2 is the nucleus, contains the cells genetic material and serves as the control center of the cell.

Which statement describes both homogeneous mixtures and heterogeneous mixtures?

How can a give a full method for the experiment of separating sand from water by filtration? 1-materials 2-steps 3-conclusion also for water and salt separated by the evaporation or distillation process

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
