Answer: Option A) the Golgi bodies and their vesicles.
The most likely explanation for the bad taste of meat that has "freezer burn" from repeated freezing is the destruction of the Golgi bodies and their vesicles.
Explanation:
Since the Golgi bodies serves as sacs for synthesis, packaging and distribution of materials in the cell, the long sharp crystals of ice will spear through the cell membrane, and then through the Golgi bodies and their vesicles.
This would cause them to spill their contents into the cytoplasm alongside the forceful withdrawal of fluids from the vesicles of Golgi bodies for freezing.
Thus, destruction of Golgi bodies and their vesicles most likely explain the bad taste of meat
Answer:
a) Toxic (gases)
d) Bacterial
Explanation:
Septic tanks are underground structures usually built with concrete or plastic in which wastewater is treated. These tanks are generally used in rural areas and are located near bathrooms and laundry rooms.
If a septic tank is working correctly, it should produce any unpleasing smell. However, when an individual perceives a certain strong bad smell it could be due to the presence of gases (low levels of hydrogen sulfide and high levels of carbon dioxide, and methane) and anaerobic microorganisms such as sulfur bacteria which also produce methane and, therefore, strong smell.
It all depends of what kind of bad smell is the person perceiving. For example, the smell of "rotten egg" is usually due to microbial pollution and gases. Although these gases are not toxic in low levels, they could become highly toxic. It is extremely important to pay attention to smell and give the appropriate mainteinance.
A neuron enters hyperpolarization when there's an efflux of the potassium ions and the influx of chlorine ions. This moving out of positively charged cations and moving in of negatively charged anions makes the neuron enter a state of negative membrane potential. If a hyperpolarized neuron is stimulated by an oncomming action potential, it fails to get excited. This is because the neuron has its potassium ion channel inactivated by the negative potential. The potassium ion channel can only be activated when the potassium ions slowly leak inside to neuron to make it enter the state of resting membrane potential.
