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.

Sodium has the atomic number 11. How many electrons are in a sodium ion, which has the symbol Na=?
AlladinOne [14]
Atomic number is the number of protons of an atom. And, given that the atoms are electrically neutral and the charge of one proton is equal to the charge of one electron, the number of electrons is equal to the number of protons. So the neutral atom of sodium has 11 protons and 11 electrons. But, the sodium ion (Na+) has one positive charge, that means that it has lost one negative charge or one electron. Then, the sodium ion (Na+) has 11 - 1 = 10 electrons. <span>Then, the answer is that there are 10 electrons in a sodium ion. 

hope this helps :3</span>

In the hershey-chase experiment, bacterial cultures infected with a virus were agitated in a kitchen blender to _____.
Phantasy [73]

The Hershey and Chase experiments showed that the inherited genetic material was DNA (deoxyribonucleic acids). In this experiment, the scientists labelled the DNA molecule with a radioactive isotope of phosphorus.

Centrifugation causes the separation of different components according to their size. So, by blending, they centrifugated the mixture of virus and the bacteria, which separated the viral protein capsule and the bacteria. Later, they found that the virus infected bacteria contains the DNA of bacteria, not the protein.

Hence, bacterial cultures infected with a virus were agitated in a kitchen blender to separate the protein coat of virus from the bacteria.
