Answer:
The strat codon is AUG
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named <em>codons </em>in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.
The codons indicating the initiation or stop points during the translation process are:
- The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.
- The end codons are UAA, UAG, UGA.
Answer:
C Allopatric Speciation
Explanation:
Evolution of two populations of same species into two separate species due to geographical isolation is called allopatric speciation.
In the given example, Isthmus of Panama serves as a geographical barrier and do not allow the interbreeding between Atlantic and Pacific fish populations of the same species.
These populations evolve genetic adaptation to make themselves better suited to the prevailing surroundings. Accumulation of genetic variations over generation leads to their reproductive isolation. Now, these two fish populations serve as two separate species as they can not interbreed.
Charles Darwin's Theory of Evolution by Natural Selection
proposes:
<span>·
</span>In each generation, more people are produced and
survive.
<span>·
</span>Phenotypic variation is heritable.
<span>·
</span>Those with heritable traits that matches with the
environment will most likely survive.
<span>·
</span>New species rise after reproductive isolation.
Charles Darwin took inspiration from economics and chose
observable data to form his theory. The speculations before his time drove him
to study how the ideas fit together, piecing information and making conclusions. The intellectual environment was both supportive and competitive,motivating the theorist.
Jean Baptiste Lamarck was a French naturalist and proposed that
species change from single-celled forms through time to complex ones.
Charles Lyell was an English geologist who discussed gradual
geological processes have slowly and steadily shaped the surface of the Earth
and that the planet must be older than most believed.
Thomas Malthus was an English economist who asserted that
human population increases faster than resources. The imbalance will cause a decrease
in the population because of famine and disease.
Mass measures the amount of matter in the substance.
Density shows the amount of matter in a given space for a substance.
Therefore meaning they both have the same mass yet the solid ball is more dense than the hollow ball.
Also the hollow ball would be filled with something such as air which would affect its buoyancy in water.
