A stroke is a kind of vascular brain injury ischemic in origin meaning there is decreased blood flow in one or more parts of the brain, most commonly caused by narrowing of arteries. The primary motor area is located in the frontal lobe, specifically the precentral gyrus or Brodmann area 4. Since the patient has lost motor activity on his right side of the body, then the more specific answer is the stroke is located in the left (contralateral because of decussation) frontal lobe, precentral gyrus.
Answer: A frog usually lives in a warm, wet area.
Explanation: They are very common in swamps or places by a body of water.
Answer is c. Natural gas.
Natural gas is a fossil fuel in liquid form that can be used as an energy source. It is found in subterranean reservoirs, often near oil deposits. It is non-renewable energy source. It takes very long time to renew. Natural gas is less pollutant as compared to coal and petroleum because when it's burned, it releases 25 % fewer greenhouse gases and pollutants. hydroelectric power, solar power and nuclear energy are renewable sources.
Antarctic fish species requires an adaptation to cold environment. Living at cold temperature environment would demand certain biological responses such as cutaneous respiration, enlarged blood vessels, and producing greater amounts of fat. Most of these fat are composed of higher phospolipid levels which are primarily due to phosphatidylethanolamine. This phospolipid is responsible for destabilizing cell membranes and make it more fluid thereby allowing unrestricted blood flow. The fatty acid composition of the membrane lipid is important for membrane fluidity, this is mainly attributed to unsaturated fatty acids which are responsible for decreasing the order of membrane lipids thereby decreasing viscosity. At extremely low temperatures, organisms with low concentration of unsaturated fatty acids would freeze cell membranes. That's why antarctic fishes have higher levels of unsaturated fatty acids.
