Selectively permeable means that cells only allow certain molecules to enter or exit a cell.
Answer:
A)
Explanation:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.Also During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make SUGAR molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as GLUCOSE.
therefore the answer would be A
Answer . There are a couple ways the average person can help with global warming. You can plant trees, (planting four is the equivalent to taking 100,000 car's carbon dioxide off the road for a year!) You can buy energy efficient light bulbs, (produces a lot less carbon dioxide, doesn't get as hot, is brighter and saves you cash!) You can buy an energy efficient car, (some diesel cars run on vegetable oil!) Turn off those lights, (don't forget to unplug them as well, or they will waste the same amount of carbon dioxide as if they were on!). If you have a pool don't heat it in the summer, (let Mother Nature do it for you.)Buy foods from your state or country, (the cars transportation your food won't waste as much carbon dioxide.. These are just a few of the ways you can do your part to stop global warming..
Answer:
He can test it.
Explanation:
The student might take a pan and wet it from both the inside and outside, trying to keep the same amount of water in both sides.
Then, the student should place the pan on the stove and start a timer.
The student will observe attentively the water on both sides to see which one evaporates first, keeping also track of the timer.
To make sure that the test is accurate, it would be best if repeated several times.
