What do you do to help the environment?

We Answered:

There are many things I do to live green and some are very inexpensive too!

~Of course, I recycle everything you can! (Ex: cans, bottles, plastics, paper, ect.)
~Buy energy saving light bulbs
~Buy things like clothes, paper, ect that are made from recycled materials
~Use reusable batteries or recycle dead batteries properly
~Use reusable shopping bags
~ When I have plastic shopping bags, I use them instead of just tossing them. I use them to pick up dog poo, line small trash cans, ect.
~Try not to use paper napkins or paper towel as much as possible. Instead use cloth napkins that can be washed.
~Try to use fewer paper plates and more washable ones.
~Take shorter showers
~Turn off lights whenever possible
~Try to buy more organic foods and local foods (for example, at a farmer's market)
~Use regular silverware, not plastic
~Use eco friendly products in replace of regular dish washing liquids, house cleaners, ect. (Greenworks)
~Use cold water to wash clothes (Tide Cold water works great)
~On a nice day, I turn off the air/heat and open some windows. You save of the cost, get a nice fresh breeze, and help the environment.
~I plant trees around your house to shade and save on using more air conditioning
~I bought one stainless steel, reusable, water bottle instead of using regular plastic ones and then getting rid of them. This one you can clean and use over and over again!
~Changed the setting on my sprinklers to use less water
~Bought eco friendly
~Walk or ride a bike wherever possible
~Carpool if possible

These are just some of the things I can think of off the top of my head that I do to help the environment. :)

How do YOU conserve energy at home and elsewhere?

We Answered:

I boil a kettle in the morning and make myself a flask of coffee then I don't have to boil it again. I bought a motorbike for the quick trips and only use the car when I have to. In SA it's important to have a SUV so you can escape carjackers.

Help With Revision - Biology - Adaption In Animals?

We Answered:

The ratio between the surface area and volume of cells and organisms has an enormous impact on their biology. For example, many aquatic microorganisms have increased surface area to increase their drag in the water. This reduces their rate of sink and allows them to remain near the surface with less energy expenditure. Humans and other large animals cannot rely on diffusion for absorption and rejection of respiratory gases, for their whole body; however, animals such as flatworms and leeches can, as they have more surface area per unit volume. For similar reasons, surface to volume ratio places a maximum limit on the size of a cell.

An increased surface area to volume ratio also means increased exposure to the environment. The many tentacles of jellyfish and anemones provide increased surface area for the acquisition of food. Greater surface area allows more of the surrounding water to be sifted for nutrients.

An animal will learn not to eat certain plants through many ways. For instance, many plants have needles (like cacti), or are a bright color, telling the animals "I'm poisonous, don't eat me".

Plants/animals compete with others for food, space, and mates (in animals' case). Ex. Weeds on a lawn compete with grass for room.

Plants conserve water by holding it in their xylem cells (like cacti in a desert where there's little or no water.) Pine trees have needle-like leaves that have a glossy coating also to conserve water and make sure the water doesn't evaporate through the stomata.
