Answer:
Explanation:
The evolutionary tree is composed of,
- Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches ⇒ Elephant species X, Y, Z
- Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor ⇒ The red spot in the graph shows the location o the most recent ancestor between species X and Y
- Root → This is the older common ancestor that all lineages share. The first one in the tree ⇒ The blue spot in the graph show the oldest common ancestor shared by the three species
Two or more lineages are more related to each other if they share a recent common ancestor -In this example, X and Y are more related to each other-. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
The right answer is A. It requires more coal mining.
In order to manufacture synthetic gasoline, the Fischer-Tropsch process involves the catalysis of carbon monoxide and hydrogen to convert them to hydrocarbon. In this chemical process, the most common catalysts are iron, cobalt or ruthenium, as well as nickel, but the latter will tend to form methane CH4 (this is called methanation). The interest of conversion is to produce synthetic crude oil from coal or gas. This process has a very good yield but requires very heavy investments, which makes it economically vulnerable to downward fluctuations in the price of oil.
Adenine, guanine, thymine and cytosine are the four nitrogenous bases that are attached to a sugar molecule<span> on each </span>side of the ladder<span>. When a phosphate, a sugar and a base form an attachment, they create a sub-unit of </span>DNA<span> called a nucleotide. Each nitrogenous base is held together by a hydrogen bond.</span>
