Answer:
2 ormore tissues working together can do a lot more. An organis structure made of 2 or more tissues that work together. The heart is made up of 4 types of tissues. The 4 different tissue types work together in the heart as they do in the other organs.
Answer:
The resting membrane potential is created and maintained due to the difference in the total charge or ions present outside and inside of the cell. The resting membrane potential depolarize if sodium come in and and potassium leaves the cell.
Explanation:
The resting membrane is maintained and created by the distribution of potassium and sodium ions. The membrane potential of a resting cell is -70mV (negative) because more sodium ions is present outside the cell than the potassium ions present inside the cell.
When the sodium ions enter inside the cell and potassium ions move outside the cell, the inside of the cell becomes more positive as compared to the outside and the membrane potential changes from -70 mV to +30 mV. The cells will depolarize due to the accumulation of sodium ions inside the cell.
>:( I had a long explanation for this & the wifi spazzed out & now it's gone.
It's B, because homeostasis is the maintaining of stable internal conditions within an organism. If a contractile vacuole expels water, it's so the cell/protist can still function without being overrun with water & thus "drown," not being able to function.
I was going to have such a more thorough explanation than this. Ugh.
Hope this helps, though!
Answer:
one motor neuron
Explanation:
Although a single motor neuron can innervate several muscle fibers, each muscle fiber is innervated by only one motor neuron
