Answer:
primary sources
Explanation:
To understand Alexander the Great achievements and death, it becomes essential for a historian to use ancient maps to discover and study the location of his empire. Historical maps show areas including Europe, Asia, and Africa that ruled by Alexander in 323 B.C.
Ancient texts by Arrian, Diodorus Siculus, Plutarch, and Quintus Curtius Rufus also helps to look into Alexander the Great life.
Alexander the Great was born in 356 BC in Macedon. His was known to be the military genius in his time who used cunning, and lateral thinking to defeat his enemies superior army.
It appears that the "ACh-producing neurons are deteriorating."
Acetylcholine, regularly abbreviated as ACh, is a little, natural particle that is a subsidiary of choline and acetic acid and fills in as an essential neurotransmitter. Neurotransmitters are synthetic exacerbates that transfer data over the hole (neural connection) between one neuron (nerve cell) and a neighboring cell (neuron, muscle cell, organ cell). On account of acetylcholine, it is dynamic both at the neurotransmitters amongst neurons and in the incitement of muscle cells at the neuromuscular intersection. It likewise stimulates discharge of organs.
The study combines chemical and biological evaluation methodologies to show that it can take up to 20 years or more for deep mud coastal habitats to recover from the damaging effects of major oil spills.
How do oil spills affect the coastline?
Oil waste interacts with sediments including beach sand and gravel, rocks and boulders, flora, and terrestrial habitats of both wildlife and humans, leading to erosion and contamination if it reaches the coastline or coast. The oil is brought to shore along with the surf and tide by waves, water currents, and wind.
How can some of the spilled oil be recovered?
A crew can attempt to confine and skim the oil if they can get to a spill in a short amount of time. Mechanical methods, such as booms and skimmers, are used for containment and skimming. Skimmers, which are adapted boats, skim the oil off the surface of the water, while booms, which are floating physical barriers, prevent the oil from spreading.

Answer:
<u>A. Oil is considered to be the resource land</u>
Explanation:
- Oil is considered to be a land resource, as oil is naturally occurring in the ancient and prehistoric rocks of the earth thus are called crude oil occurs in raw forms. About 84% of oil reserves occur in offshores.
- The total estimated oil reservoir of oil is based on the geologic data obtained from the oil wells. With approx, 4.1 million barrels of oils are held in strategic reserves.
- Techniques for the estimation of oil in places are Volumetric methods, material balance methods, production decline curve method. New research suggests that the oil reserves have been found in Canada and the Antarctic circle.
- Maximum reserves have been found in Venezuela, Saudi Arabia, and Canada as these lands have great deposits of mineral sand and sedimentary rock. And its believed 13 % of oil reserves are hidden and undiscovered in world lands and oceans.
