The answer is 'negative charge and contains less sodium than outside of the cell'. This is called the resting potential. After depolarization, the ion channels open up and the intracellular sodium ions are pumped out of the neurons hence making the inside of the neurons electronegative compared to the extracellular matrix. The membrane potential is usually -70mV.
Answer:
The correct answer is
d. heating evaporative cooling and mineral transport
Explanation:
Plants transpire to expel excess heat energy by a process known as evaporative cooling. As the water involved in transpiration evaporates, heat energy is transferred from the plant system into the surrounding environment cooling down the plant.
During transpiration, the stomata of the plant are open allowing the outward flow of the evaporated water and also the open stomata enable the plant to absorb carbon dioxide (CO2) from the atmosphere. The carbon dioxide is required in photosynthesis for the formation glucose while producing oxygen as well.
The water also transports nutrients dissolved in it as it is being transported to the leafs for evaporation. These nutrients are thus delivered tm all parts of the plant.
To find the answer, take 55 and divide it by 1.85 to get the thickness of one card. In this case the answer would be 29.72973 cm. each.
1. Rainbow (white light is split into its subsequent wavelengths)
2. Light enters through the cornea, is adjusted by the lens, the cones and rods of the retina are responsible for the perception of color and shadows, which are sent through the optic nerve to the occipital lobe of the brain.
3. Sound waves are intercepted by the pinna, travels through the auditory canal, reverberates on the eardrum, the vibrations travel through the ossicles of ear (hammer, anvil and stirrup), continuing to the cochlea and are sent through the auditory nerve to the brain.
4. A medium
5. Vibrations
6. All
7. Faster
8.Their kinetic energy increases
9. Conduction, convection and radiation
10. The heating of metals in the mantle, creates a current which slowly moves the plates above it.
