<h2>Answer </h2>
There are 64 codons that is contained in the mRNA.
<h2>Explanation </h2>
The codons contained by the mRNA produced by DNA consist of three nucleotides and a single amino acid. The mRNA uses uracil nucleotide as a base. The genetic code is known as a codon. There are almost sixty four codons but three of which do not code for amino acids. The codons found in the base pairs of strands of mRNA during the process of translation.
Lithosphere
13 major plates
Asthenosphere
Explanation:
The surface or lithosphere of the earth is broken into about 7 major plates that floats on the liquid asthenosphere.
The analogy above describes the theory behind plate tectonics.
- The crust and the rigid part of the upper mantle forms the lithosphere.
- The lithosphere is broken down into series of pieces called plates.
- There about 13 plates on earth surface.
- The rigid plates moves on the weak asthenosphere below as a result of convection currents.

Narwhal population is increasing exponentially since 1970, due to some factors like increasing Birth rate, immigration etc.
If you are looking for website, then you should find for wider topic like search for Narwhal only instead of it's population/growth
Hope this helps!
Answer: B. evaporation, condensation, precipitation
Explanation:
The cycle that ensures that fresh water is available is called the Hydrological cycle and it involves several key processes.
As it is a cycle, none of the processes can be considered first but if any could, it would be evaporation. This is when water on the surface is heated and becomes water vapor (gas) and rises towards the atmosphere.
Condensation occurs as the water vapor rises because the further up you go, the colder it gets. These water vapor particles will thus condense and clump together to form clouds.
These clouds keep getting larger until they are too heavy to be carried by the atmosphere in which case they fall to the ground as rain the process known as precipitation.
The population is exceeding what the Earth's resources can supply we hardly have enough food for certain countries and also to places like China who do not believe in global warming or anything of that sort pollute the air consistently which is why they've been in a fog for the past few weeks I believe and not only that if it continues we will use up all of our natural resources the more people the more resources
