A student set up an experiment to investigate osmosis as shown. The student used visking tubing which is a partially permeable membrane. The student put 25 cm of 20% sucrose solution into visking tube 1 and 25

cm of distilled water into visking tube 2. Both tubes were placed in a 5% sucrose solution and left for 1 hour.

20% sucrose solution

visking tubing

5% sucrose solution

tube 1 tube 2

Explain how and why tube 1 and tube 2 would look different after one hour.

the answer is a) a shiprock was formed by igneous process

a few examples of ethical concerns involving genetically engineering of humans include

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

when a previously occupied environment was disturbed that kills much of all its

community
