Your answer is D. Muscles contract and thus pull on bones to cause movement.

Your guess is correct it is D. I know because I like to read about the human body, it's very interesting to me how it works. Here's some advice, never second guess yourself, because it happened to me before. :) Hope I helped!

Which electrons have the most energy in an atom?
Ket [755]
The correct option is THE ELECTRON IN THE OUTERMOST ELECTRON SHELL.
Different levels of energy exist in the atom of an element and these levels are filled with electrons. The electrons in the innermost shell has the lowest energy level while the electrons in the outermost shell has the highest energy level. For an electron to increase its energy level, it has to move to an higher shell; and to decrease its energy level it has to move to a lower shell.

Answer:

1. You will be unable to smell

3. Your olfactory receptor cells will no longer be able to respond  to molecules trapped in the mucus.

Explanation:

The Olfactory receptors are the receptors present in the olfactory neurons which detect different odorants or smell.

The olfactory receptors are embedded in the epithelium or mucous lining of the nose in which one extension of the cell body reaches the epithelium surface and branches into cilia like structures which sense the odour.

If the axons of the olfactory cells are broken then the cells will not be able to respond to the molecules trapped in the mucus and thus no detection of odour. The signal will not be generated in response and thus will not be sent to the brain. Thus, the person will not be able to smell.

Thus, Options-1 and 3 are correct.

UNO [17]

Answer:

1000 mM

Explanation:

Using V = -60 mV㏒₁₀[K/K'] where V = membrane potential = -60 mV, K = intracellular concentration = unknown and K' = extracellular concentration = 100 mM

So, V = -60 mV㏒₁₀[K/K']

-60  mV = -60 mV㏒₁₀[K/K']

dividing both sides by -60mV, we have

-60  mV/-60 mV = ㏒₁₀[K/K']

㏒₁₀[K/K'] = 1

taking antilogarithm of both sides, we have

[K/K']  = 10¹

multiplying both sides by K', we have

K = 10K'

K = 10 × 100 mM

K = 1000 mM

So, the intracellular Cl- concentration is 1000 mM
