<span>Let's consider a scenario in which the resting membrane potential changes from −70 mV to +70 mV, but the concentrations of all ions in the intracellular and extracellular fluids are unchanged. Predict how this change in membrane potential affects the movement of Na+. The electrical gradient for Na+ would tend to move Na+ Outside the cell (extracellular) while the chemical gradient for Na+ would tend to move Na+ Inside the cell (intracellular).
The electrical gradient is defined as the + goes to the - and the - goes to the +
Na + has a positive charge, but there's more positive charge inside the cell than outside (due to potassium), therefore, Na+ goes extracellular (out)
The concentration gradient considers that the ion will go from the most concentrated to at least concentrated by passive diffusion so no trans-membrane proteins in the game attention.Na + is very concentrated in extracellular and few intracellular, therefore, it tends to go intracellular (in).</span>
Answer:
The observation is an evidence of static electricity.
Explanation:
Static electricity refers to the stationary electric charge that is produced by friction. In other words, this kind of electricity is created when objects (2 objects for example) that are not good conductors of electricity are rubbed together.
During the rubbing process, electrons from the objects come in contact leading to the creation of a stationary electric charge. A good example of static electricity is when you are combing your hair and you see a spark in the mirror.

Answer:
Cellulose is considered as complex carbohydrates
Explanation:
It is beacause usually it is found outside of the plant and it is so hard and rigid so it is hard to digest. They are usually used in making colths.
Adaptation is a phenomenon that is about adjusting certain features to environmental conditions. Ie. birds are adapted to flight as they possess wings, very efficient lungs etc. or tropical plants are adapted to high temperature and humidity as they modified their photosynthesis process. but if some creature is adapted to the specific habitat or conditions, it is hard for it to manage in another habitat/different conditions. ie. birds are fast in the air but on the ground they are quite weak and prone to predators' attacks.
