each cell in the human body contains thousands of different enzymes responsible for regulating reactions within the cell. which statement explains why a single enzyme is unable to regulate a variety of reactions?
a. the binding of a product and an enzyme is specific.
b. the binding of a substrate and an enzyme is specific.
c. the enzyme is consumed by the products of the reactions. d. the enzyme is consumed by the substrates of the reactions
Answer:
A
Explanation:
Edge 2021
A single enzyme cannot regulate a variety of reactions because of the binding specificity of the substrate and enzyme. option C is correct.
Key-lock Theory:
It states that the enzyme and substrate are as lock and key. As there is only one specific key of a lock. Same there is only a single substrate (Key) for the Enzyme (Lock).
This specificity is because of the specific structure of the enzyme that allow only a specific substrate to bind.
Therefore, a single enzyme cannot regulate a variety of reactions because of the binding specificity of the substrate and enzyme.

Explain Darwin’s theory of evolution
Answer:
Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

Genetic engineering techniques can be used when analyzing and manipulating DNA and RNA. Scientists used gel electrophoresis to study transcription of gene L and discovered that mRNA strands of three different lengths are consistently produced. What explanations best accounts for this experimental result?
Answer:
the precursor messenger RNA (pre-mRNA) of the L gene underwent alternative splicing, thereby producing three different mRNAs that have different lengths
Explanation:
In eukaryotic organisms, transcription produces a precursor mRNA (pre-mRNA), which is a non-processed RNA sequence that contains both non-coding regions (i.e., introns) and coding regions (i.e., exons). Subsequently, this pre-mRNA is converted into a mature messenger RNA (mRNA) by a process known as 'alternative splicing', where introns are removed and exons and exons spliced together to form a contiguous coding sequence. During alternative splicing, differential combinations of exons can be produced from the same gene, producing different mRNAs with different lengths.
The experimental results with the gel electrophoresis of the transcription of mRNA are due to the alternative splicing.
What is alternative splicing?The genes are the codes that are enabled the formation of the DNA and RNA by expression. The transcription is the process of formation of mRNA from DNA template.
The mature mRNA is formed by the alternative splicing of the introns and the joining of exons for the functionalization. The process of alternative splicing results in the formation of the mRNA of multiple length.
The gel electrophoresis bands resulted have multiple length of mRNA. The results are the explanation for role of gene L in alternative splicing of mRNA.

On your Spring Break in Mexico, you take a break to count the starfish in a tidal pool. You notice that there is a rare recessive trait that causes the starfish to have 6 legs instead of 5. Of the 27 starfish you can find, only 1 has 6 legs. What are the allele frequencies for this population
Answer:
0.04 for 6 legs starfish and 0.96 for 5 legs starfish.
Explanation:
The allele frequency for the 6 legs starfish is 0.04 whereas, the allele frequency for the 5 legs starfish is 0.96 because there is only one 6 legs starfish in the given population as compared to 5 legs starfish. The low population of 6 legs starfish is due to the presence of recessive allele while on the other hand, higher population of 5 legs starfish is due to the presence of dominant allele. The allele frequencies for both population is done by dividing the allele of interest by total number of alleles present in the population.

While having dinner, your little sister says she learned about energy and matter at school today and that the food you are eating and the energy you receive from it have been consumed and used previously. Your family is surprised by this and since you are the older sibling, they have asked you to explain whether your little sister is correct or not.
5-8 Complete sentences
Answer:
She is correct
Explanation:
The reason why she is correct because everything had come from something. For example, if a farmer is eating an apple, takes the seeds out, and plants them, the apple you are eating right now came from the farmer's apple. This means that it had been used previously. An example of it being consumed previously is if an animal had eaten an apple, put its feces on the ground, and left, the seeds from the apple will eventually grow. This could have been how your apple has grown. This could be an example of most foods we eat.
