The resistance potential of membrane of cell is altered by voltage gated Ion channels opening
Explanation:
The trans-membrane proteins that form the Ion channels in a cell membrane is referred to as voltage gated Ion channels. When there is a change in the potential of the cell membrane this channel is formed. It alters the resistance potential of membrane and alter the shapes of the proteins and controls there opening and closing.
Trans-membrane protein channels allow the ions to enter the membrane through diffusing process. This voltage-gated channel is specific to molecules of ions. The opening of the channel is induced by change of concentration in the membrane
Answer:
<u>C</u>
Explanation:
Kinetic Energy formula :
<u>K.E. = 1/2mv²</u>
<u />
=============================================================
Given :
⇒ mass = 0.17 kg (needed)
⇒ distance = 20 m (not needed)
⇒ velocity = 22 m/s (needed)
============================================================
Solving :
⇒ K.E. = 1/2 × 0.17 × (22)²
⇒ K.E. = 11 × 0.17 × 22
⇒ K.E. = 1.87 × 22
⇒ K.E. = 41.14 ≈ <u>41 J</u>
The circle of illumination just touches (but does not illuminate) the antarctic circle on or about June 21. The Earth is tilted, and this tilt leads to the southern and the northern part of the Earth having the day length variation. June, 20-22, is considered the summer solstice, where the length of the day in the northern hemisphere is longest whereas in the southern hemisphere it is the shortest. During this period, the circle of illumination or the rays from the Sun, barely touch the Antarctic circle. This causes darkness and night in Antarctica.
