A stimulus causes sodium channels to open, allowing sodium ions to enter the neuron.


The neuron becomes more positive.


Potassium  channels open, allowing potassium ions to exit the cell.


Sodium channels close and the cell gradually returns to resting levels.

Okay well the signal or the movement coming through the neuron(and its axon)  is about the ions. The ion is a charged like particle, such as Na+ (If you remember that). Na+ is a sodium ion. So most of those ions I was talking about before just simply flow in or out of the cell. I hope this helps! <3

question 4: an atom with 7 protons, 6 neutrons, and 7 electrons, has an atomic mass of blank amu. (Enter a whole number) ​
Ivanshal [37]
Answer : An atom with 7 protons, 6 neutrons,
and 7 electrons has an atomic mass of 13 amu.
Explanation:
As we are give that,
Number of protons
7
Number of electrons =7
Number of neutrons =6
As we know that,
Atomic number =Number of protons = Number
of electrons =7
Atomic mass = Number of neutrons + Atomic
number
Atomic mass = 6 + 7 = 13 amu
Therefore, the atomic mass is, 13 amu

A field of corn contains a certain amount of food energy. Compare the following situations and then answer the questions. Use th
trasher [3.6K]

Before assessing the two given cases, an assumption needs to be made about the digestion of the two types of food items, corn and beef. Let us assume that both get digested by expending same amount of energy by the human body. Let the amount of energy at producer level be an arbitrary X.

Case 1: Corn to human:

Since corn is at the producer level, it will have X amount of energy. The transfer of energy from corn to human will take place with a loss of 90% energy at the producer level. Hence the humans will receive 10% of X amount of energy.

Case 2: Corn to cow to human:

Since corn has X amount of energy, only 10% will pass to the next level, i.e. cow. So cow has 10% of X. Cow transfers only 10% of the energy that it has. Hence humans receive only 10% of 10% of X amount of energy.

It can be seen that humans receive more energy in case 1 than case 2. Hence we can say that it is more efficient for humans to feed on corn.
