This statement is true: <span>The mineral ores for gold and silver are commonly found in the earth's crust.
These two types of metals are known as native metals because they are naturally occurring within the Earth's stratosphere. These metals are usually found through mining processes because they are often found mixed with sediments and other soil components. One method of acquiring gold is called gold panning while silver is obtained mixed with silver sulfide and sulfosalt minerals.</span>
The American Heart Association recommends eating at least 7 <span>ounces of oily fish per week to help reduce your risk of heart disease.
In short, Your Answer would be Option A
Hope this helps!</span>
Answer:
resultant force, force, acceleration, physics, and rotation
a. parsimony; simplest; fewest
When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of <u>parsimony</u>, which means we choose the <u>simplest</u> possible hypothesis. In phylogenetic analysis, that means selecting the tree that represents the <u>fewest</u> evolutionary changes or mutations.
Explanation:
Phylogeny describes the evolutionary history of on organism or group of organisms.
A phylogenetic tree structure is used to describe the relationship between various organisms which have originated from common ancestors.
The Principle of Parsimony is best applied while constructing phylogenetic tree.
This principle emphasizes on simple observations on a phylogeny which requires only few changes or variations which explain for the difference between the phylogenic sequences.
This tree structure will only have few specific genetic variations or mutations or evolutionary changes which took place through new appearance of a trait or disappearance of an existing trait.
<u>ANSWER:</u>
When a supergiant runs out of fuel, the object formed is either a black hole or a neutron star.
<u>EXPLANATION:</u>
- Supergiant are very large stars in the galaxy that end their lives very quickly.
- When a supergiant star loses its fuel, it blows itself by a supernove explosion.
- When supernove explosion happens, the supernova outshines other stars in the galaxy and then slowly faded away leaving a dense object called black hole or neutron star.
- This black hole or neutron star is surrounded by a mass of very hot gas and the elements of the supergiant star get scattered into the space.
