Answer:
Seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor.
Explanation:
Answer: True
Explanation:
<u>A cell membrane consists of a lipid bilayer made of polar phosphate head and a nonpolar lipid tail.</u> It is semipermeable and regulates the transport of materials through it. For this,<u> it is selectively permeable</u> and since it is made of lipids, hydrophobic and small polar molecules can diffuse easily through it by simple diffusion and down their concentration gradient. However, polar molecules, large molecules (such as glucose) and ions are not able to pass through it because they are repelled.
To accomplish the transport of these molecules that can not diffuse, proteins embebbed in the membrane function as carriers that enable the transport of polar molecules, large molecules and ions by passive (through facilitated diffusion, down its concentration gradient) or active transport (movement against its concentration gradient).
1. Consumers are basically animals and producers are plants. Producers (ex. grass) make their own food and get energy from the Sun. Consumers (ex. rabbit) receive food and nutrients from producers and/or consumers.
2. Decomposers are important because they break down dead plants and animals. If they weren't there, plants, wouldn't get nutrients and waste would pile up.
3. Sorry-- I don't remember what chemosynthesis is.
4. I'd suggest looking up a food chain and going to images-- it's simple to find a diagram with all five of those. Sorry-- I can't think of any off the top of my head
5. The Sun.
Sorry-- I've only got some of it. I'm sure looking up #3 and #4 are easy to find answers to. Hope this helps. :)
I would say read some class work, then find a video on YouTube explaining it
Answer:
All the organisms in a forest will <em>INTER</em><em>A</em><em>C</em><em>T</em><em> </em>with one another. ( Ecosystem )
hope it helps!
