<span>Diffusion is the movement of molecule from a place of high concentration to a place of low concentration through a semi-permeable membrane.
Osmosis is the movement of molecules from a place of high <u>water</u> concentration to a place of low water concentration through a semi-permeable membrane
So probably the answer is <em><u>C</u><u></u></em></span>
Your nose and your mouth are both a portal of entry into your body. If you cover one and not the other it defeats the purpose because Bacteria can still enter the system. They are both part of your respiratory system.

Hypothesis: I believe the seeds will grow 1-2 feet based on my research
Procedure: I put my seeds in small pots and put on a self I have outside in the sun. They can absorb good sunlight this way
Growth of seeds: all varied but stayed within 3 feet
Type of seeds:
1. Cornflowers
Growth
Day 3: about 2 inches
Day 6: about 5 inches
Day 9: about 12 inches
Day 12: about 22 inches
Day 15: about 34 inches
Interpretations: cornflower- the meaning is wealth, prosperity, fortune and friendship.
I don’t know what was asked in the lab...
Conclusion: my hypothesis was kind of correct. My cornflowers grew to be over 2 feet, but not by much. Some even stayed under, but not by much I say again. This was a fun and educational experience and I learned a lot about this wonderful plant. I hade no idea that it was even a real thing before this project! I learned that different flowers grow at different paces, even if they get the same amount of sunlight and water.
Answer:
Free fall.
Explanation:
When astronauts sleep in space, they sleep in small cabins or in sleeping bags that are attached to the wall or ceiling of the station. Everything is weightless as there’s no gravity in space. So while sleeping there is a chance of floating around and bumping into things. Astronauts use sleeping bags that can be tethered to the wall or ceiling to solve this problem. Also the tethered sleeping bags provide a normal sleeping environment to the astronauts as they can feel pressure on their back and head. Their sleeping cabin is well ventilated as they can wake up with breathing trouble as a result of the inhalation of their own exhaled carbon dioxide which formed around their heads as a bubble. They use earplugs and a sleep mask to block the noise and light and can sleep vertically or horizontally. Compared to earth, sleeping is a bit different in space.
The answer is d. Ingestion, digestion, absorption, elimination.
There are 4 phases of the digestive system function:
1. Ingestion - the process of the food entering the mouth.
2. Digestion - the process of breaking the food into small particles.
3. Absorption - the process of the absorbing small food particles into the blood from the intestines.
4. Elimination - is the process of removing the waste out of the body.
