Answer:
Explanation:
After the gated channels close, which is as a result of depolarization of voltage, the positive charge that has been increased in the cell will make the potassium channels to open and this will gush out of the cell through its electrochemical gradients. When potassium ion move out of the cell, the membrane potential begin to get to resting potential.
The heat messes with the pili muscle.
Answer:
A. Wires
Explanation:
Electrical conductivity is basically how much electrical current a type of material can carry through it, so in other words it is the rate electric current can pass through it.
As you know, electrical devices rely on electricity (it's in the name) for it to function. Wires are often used in electrical equipment. Wires help connect devices to power sources. They need to be good electrical conductors in order to deliver electricity to the devices and powering it on.
Answer:
Up
Explanation:
The force is the biggest (8N) so that's why it will move up
Answer:
Option 1, a charged end and a noncharged end
Explanation:
Complete question
If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____
- a charged end and a noncharged end
- three fatty acid molecules, all pointing in different directions
- two fatty acid molecules pointing in different directions
- both a saturated fatty acid and an unsaturated fatty acid
- two charged ends
Solution
The structure of phospholipids consists of the following groups and molecules –
a) A glycerol molecule
b) Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature
c) Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.
When the phospholipids are placed in water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.
Hence, option 1 is correct
