Answer:
<h2>a. 1000 X 2^8</h2>
Explanation:
As given;
Initial population of bacteria= 1000;
Log phase growth is exponential phase, period in which bacteria gets double.
Generation time= 15 minutes;
it means, bacteria get double in every 15 minute,
so after 2 hours, bacteria will have 8 generation times;
so the final generation of bacteria is =1000 X 2^8.
Final bacterial generation after two hours = 256,000(1000 X 2^8)
Answer:
Melanin helps the mouse survive because of the fur color. Its color helps it to blend into its surroundings, making it a lot harder for predators to kill it, as the predators have a harder time seeing the mouse.
Explanation:
It's B
Explanation:
Because the fossil record shows how organisms have evoluate from relatively simple organisms to more complex organisms
Answer:
introduces a premature stop codon into the mRNA
Explanation:
A nonsense mutation is a mutation in which an amino acid–specifying codon is changed into a termination codon or stop codon. A stop codon is a codon that does not code for any amino acid and serves to terminate the process of protein synthesis as ribosomes encounter it on the mRNA.
There are three stop codons: UAA, UAG, UGA. A nonsense mutation introduces a stop codon in place of an amino acid encoding codon. It results in the formation of truncated protein which is shorter than the normal protein. Truncated proteins are mostly nonfunctional.
