Answer:
The correct answer is option D) "The enzyme will use any tRNA species but is highly specific for a given amino acid".
Explanation:
Aminoacyl-tRNA synthetases, also known az tRNA-ligase, are the enzymes that catalyze the attachment of the appropriate amino acid onto its tRNA. It is false to affirm that these enzymes will use any tRNA species but is highly specific for a given amino acid. In fact, aminoacyl-tRNA synthetases are highly specific for both, tRNA species and amino acids. Kinetic studies show that aminoacyl-tRNA synthetases reject wrong tRNAs during catalysis.

Answer:
Burning fossil fuels
Explanation:
Greenhouse gases are the main human causes of global warming.They basically act like a warm blanket around the earth and trap heat. Causing the earth to get warmer and temperatures to rise.
The two main greenhouse gases we add to the air are methane and carbon dioxide.
The main source of carbon dioxide is the burning of coal,oil,gas and petrol(fossil fuels)in power stations.
We produce far more carbon dioxide than any other greenhouse gas. And its production has been on the rise since the industrial revolution.
So the burning of fossil fuels resulting in carbon dioxide is the main cause of global warming.
<span>The correct answer is a dichotomous key. Basically, you use the key to decide what species an organism is by looking at what traits it has, and if it doesn't have some traits you can instantly rule out a large number of species which brings you closer to your answer of what the species is that you're looking at.</span>
Answer: Genus
From largest to smallest, the pyramid of binomial nomenclature goes: kingdom, phylum, class, order, family, genus, species.
The correct answer would be
