Answer:
tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.
Answer:
A liquid, and example is water, since it can form into the shape of its container.
Explanation:
Answer:
I believe the options are:
1) Present day species developed from earlier species
.
2) Some species die out when environmental changes occur
.
3) Complex organism develop from simple organisms over time
.
4) Change occurs according to the needs of an individual.
The answer is 4) Change occurs according to the needs of an individual.
Explanation:
Theory of Evolution:
- By definition, evolution is the process of change in an individual's/organism's characteristics over time. Evolution occurs through mutations in the genetic information or DNA of an individual.
- The theory of evolution states that all organisms change over time and are descendants of a single common ancestor. Species adapt to the changing environment by introducing variations in their DNA over millions of years. Harsh environment conditions eliminate organisms that cannot adapt to the changing environment and only the fittest survive. This is called natural selection.
- This process, occurring over millions of years, results in the formation of an entirely new species.
- The theory of evolution is contrary to the concept of Lamarckism or inheritance of acquired characters which states that characters that an organism acquires during its lifetime can be passed on to its offspring.
Answer: A short incubation time runs the risk of a false negative on the VP test, since not enough time may have elapsed to produce an adequate amount of acetoin to give a positive result. The pH change associated with mixed acid fermentation occurs fairly quickly and is less likely to be affected by shorter incubation.
b) The VP test would benefit most from a longer incubation time because it takes a while for the 2,3-butanodiol to be produced.
Explanation:
A punnet square is a chart to help figure out the possible genotypes of two organisms' offspring.
