Protein synthesis consumes four high-energy phosphate bonds per added amino acid. Transcription consumes two high energy phospha
SVEN [57.7K]

Answer:

30 protein molecules per mRNA molecule

Explanation:

In this problem, it is necessary to have into account that the transcriptional process requires six (6) phosphate bonds to synthesize one (1) codon (i.e, each three nucleotides), and also discards 95% more energy to make mRNA, it means 19 times this amount of energy >> 6 x 19 = 114 bonds. In consequence, transcription requires 120 phosphate bonds (6 + 114 = 120), while translation requires four (4) phosphate bonds per codon. From this deduction, it is possible to find the number of protein molecules synthesized with regard to the energy cost of the translation process and the transcriptional process >>> 120 bonds (transcription) /4 bonds (translation) = 30 protein molecules.

Select the correct answer.
Marizza181 [45]

Answer:

Option D, the "biological ladder"

Explanation:

The food chain is the network of organism in which all are dependent on each other for their food, energy source and survival.  

The circle of life depicts the time frame starting from origin of a life form till its death and the intermediate stages.

The tree of life basically determines which organism has evolved from which other organisms.  

The biological ladder represents the development of species from simple form to a much complex form.

Hence, option D is the right metaphor

31. The data in the accompanying graph show evidence of disease in the human body. D 38 - - E Body Temperature (°C) 377 А IDOT B
shepuryov [24]

Homeostasis keeps the organism in a dynamic equilibrium within the homeostatic range. <em>A </em><em>disruption i</em><em>n </em><em>dynamic equilibrium </em><em>is indicated by the </em><em>temperature </em><em>change between point C and D.</em> Option C is correct.

<h3>What is homeostasis?</h3>

Homeostasis is the organism's capacity to keep the body in constant internal equilibrium, even when the external environment is oscillating.

Homeostasis is critical to keep the correct internal functioning of the body.

Different functions -blood pressure, body temperature, respiratory rate, and blood glucose levels, among others- are kept in a<u><em> </em></u><u><em>restricted range</em></u><u><em> </em></u>around a reference point, even though external conditions may be changing.

When a sudden change occurs in the internal functioning that disturbs this equilibrium, the organism counters it back by negative or positive feedback.

<h3>Graph interpretation</h3>

In the exposed graph we can see,

  • The restricted range of homeostasis at a constant temperature around 37ºC.

  • Six reference points (A-F) withing 12 hours.

  • Dynamic equilibrium is kept in the range of homeostasis around 37ºC, excepting for point D that reaches 38ºC.  

The references point A, B, and C suggest that during the first 10 hours, approximately, the body was in equilibrium.

A change in the internal functioning broke the equilibrium, rising temperature to 38ºC, out of the homeostatic range.

The organism took the internal values to their original state, and at points E and F, the organism was in equilibrium again.
