Answer:
it is poisonous or harmful to the human body
Answer:
cell growth and manipulation
Explanation:
The nucleus of the cell controls cell growth and manipulation. This involves regulating gene expression, initiating cellular reproduction, and storing genetic material necessary for all of these tasks. In order for a nucleus to carry out important reproductive roles and other cell activities, it needs proteins and ribosomes.
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.
Answer: Option D.
The atoms and molecules of the liquid water are moving, and the atoms and molecules of the
table are not moving.
Explanation:
The atoms and molecules of the liquid water are moving, and the atoms and molecules of the table are not moving and this is because the atoms and molecules of liquid water are closely packed together and they collide to each other often, thereby moving in random motion in all directions.
The molecules of solid cannot move because they are closely packed together and there is a very strong of attraction which make them to only vibrate and not move and this make solid to have definite shape.
