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.
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.

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.
