Oil and natural gas were formed from the remains of prehistoric plants and animals—that's why they're called fossil fuels. Hundreds of millions of years ago, prehistoric plant and animal remains settled into the seas along with sand, silt and rocks.
Complete question:
You will find the image of the skulls in the attached files.
Answer:
1) 2 similarities between each of the skulls might be the presence of the nasal spine, and the interdental space.
2) The size of the skull seems to be the most noticeable change in skull anatomy between the dawn horse and the modern horse.
Explanation:
- Each of the nasal bones in horses ends in a protuberance named "the nasal spine". These spines converge in the distal portion of the bone. These spines and the incisive bone delimitates the space called the naso-incisor notch. In the attached figure you will see the nasal bone in red and the nasal spines. This structure is present in all the skulls in the same position.
- The interdental space is the space left between the front teeth and the back teeth. It is useful to recognize a male from a female in modern horses. This space can be found in all the skulls. You will see it in blue in the image.
The biggest change in skulls between the dawn horse and the modern horse is the size. The skull keeps the original shape or very similar shape but varies in length and height.
Answer:
Lack of government support, costly affair, and needs maintenance.
Explanation:
- Wind energy is a renewable source of energy as it's driven by the power of the sun. This source of energy is an alternative source to fossil fuels.
- But it's not followed everywhere due to the lack of support from the government officials as not all policies support the generation of wind energy.
- Also many are not aware of how to harness the power of wind, for the most developing nation its costly and need to be looked after.
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. :)
