Oil and fossil fuel were shaped from the remains of prehistoric plants and animals. That is the only reason we do refer them as fossil fuels. Long time ago, the prehistoric plants and animal remains both were settled into the seas beside the sand silt and the rocks. As the rocks and silt both were settled down layer by layer amassed in rivers on coastlines and on the bottom layer of the ocean manufacturing the organic material.
With the passage of time, increasing pressure and temperature modifies the mud sand and silt into rock and slowly cooks the organic matter into fossil fuels. Fossil fuel is controlled within the<span> rock forming exactly the same way a sponge is holding the water.

However, science and technology,in no time, was developed to boost the industries ability to see what lies under the earths surface.
Moreover,the geologists studied rocks on the earths surface and underground. They created a map of the rocks wherever they thought oil and gas might be found. Engineers use this natural science map to drill a well below the earths surface. </span>
The answer is co-dominance
Hope this helps (:
Answer:
The correct answer is: C. Active Transport.
Explanation:
Because Na+ and K+ are ions, which makes them <em>charged molecules</em>, they can only diffuse through the cell membrane when using specialized protein channels. This is called <u>facilitated diffusion</u> and is a form of passive transport because sodium and potassium move <em>following their gradients</em>, which are made of the difference in concentration between the inside of the cell and the outside of the cell. For example, potassium is highly concentrated inside the cell and poorly concentrated outside the cell, so potassium diffuses from the inside to the outside to even the concentrations.
But the question asks in which process Na+ and K+ move in and out of the cell SIMULTANEOUSLY, so the answer is actually <u>active transport</u>. Active transport is the opposite of passive transport. While passive transport occurs naturally and doesn't need ATP (energy) to happen, active transport needs ATP because it moves molecules AGAINST their gradient. One of the most famous and important structures involved in active transport is the Na+/K+ pump, which consists of a <em>specialized protein using energy to enter 2 potassium ions and take out 3 sodium ions at the same time</em>. This Na+/K+ is fundamental to maintain the gradients, which are important for the correct functioning of many cells.
Without oxygen, life cannot be sustained as it is an essential reactant in the respiration process. So the evolution of photosynthesizing bacteria increased the amount of oxygen in the atmosphere through converting water and carbon dioxide into oxygen with the help of sunlight. This provides a suitable environment for plants and vegetation to grow; plants also photosynthesise so they encouraged the increase of oxygen in the atmosphere even further, sustaining a suitable environment for the Animalia kingdom to evolve. Thanks to this, we now have a huge range of different modern species of animals and plants.
