Correct option is A)
There are electrical and concentration gradients in neurons that induce the sodium ions to enter the cell. The resting potential is maintained because the channels for sodium ions are closed. The membrane remains impermeable to sodium ions in the rest state. The membrane is more permeable to potassium passage. The potassium ions leak through the membrane at a greater rate than sodium enters. There is loss of positively charged ions from the inner part of the cell membrane. The inner part of the membrane carries a relatively more negative charge than the outer part of the cell membrane.
Thus, the correct answer is option A.
Answer:
Contusion
Explanation:
Contusion is as a result of bruises and it happens when an injured capillary or blood vessel leaks some amount of blood into the surrounding area. Contusions are a type of hematoma, which refers to any collection of blood and can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion is common in 20–30 percent of severe head injuries.
Answer: Structure of an Animal Cell
Explanation:
The first part of the cell theory states that all living things, whether small or big, simple or complex, irrespective of species or kingdoms, are made up of either one or more than one cells. Living things or organisms that are made up of one cell are called unicellular or single-celled organisms.
The population of fish would slowly begin to die out as the deeper the water the less dissolved gasses there are.
