The answer is B. hope you get it
False, the description is incorrect.
The only right answer is oil or lipid or fats. These lipid macromolecules are the only substance needed in order for these vitamins A, D E and K to be absorbed by the cell and be used in many cellular activities.
Answer:
This question lacks options, options are: Mr. M's cells are depolarizing too easily. Blocking Nat channels will make it harder for them to depolarize, bringing their sensitivity back to normal O Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Kt channels can stay open and his cells can repolarize properly. Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Na /K+ ATPase can move Kt out of the cell effectively O Blocking Na* channels cannot help- it will only make his cells fire less, and he already has a weak heartbeat. Mr. M's cells are not repolarizing properly. Blocking Nat channels will help them repolarize normally, bringing their resting potential back to normal.
The correct answer is ''Mr. M's cells are depolarizing too easily. Blocking Na+ channels will make it harder for them to depolarize, bringing their sensitivity back to normal.''
Explanation:
Calcium administration is an emerging treatment modality aimed at restoring the transmembrane electrical gradient of cardiac myocytes. It probably achieves this goal by reducing the resting membrane potential of cells. Calcium antagonizes the effect of hyperkalemia on cardiac conduction, that is, it antagonizes the effects of K on the heart. Its onset of action is immediate, in a few minutes. Calcium gluconate antagonizes the excitability of the cardiac membrane, that is, it decreases the excitability of the membrane and it does not affect serum levels, it is generally accepted that calcium should be administered when there are ECG changes associated with hyperkalemia.
Answer:
External Acoustic Meatus occurs in the temporal bone
Explanation:
External Acoustic Meatus is also known as external auditory canal. This canal is circular in structure and contains cartilage, bones, ceruminous gland.
External Acoustic Meatus is located on the temporal bone. This bone is located on the the lateral side and the base of the skull. Four parts of temporal bone are mastoid, squamous, tympanic and petrous.
Cancer cells are less likely than normal cells to undergo _apoptosis______, or programmed cell death.
Apoptosis is synonymous to programmed cell death
Explanation:
Programed cells death of the cell is required to maintain proper tissue homeostasis. Examples of when apoptosis is necessary are when a cell may have errors in its DNA replication process. Apoptosis ensures the cell does not continue dividing and generating cells with the error. Other forms of damage to a cell that is hard to repair also require that the cell undergo apoptosis.
In cancer cells, apoptosis pathway faulted and even when cells are required to undergo programmed cell death, such as in the case when lethal mutations occur, the cell continues to divide creating many cells that have the defect. This is what creates cancer tumors,
