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
I think it’s A, begins to change :))
Depending on the model,same gas mileage,no,precisely
Answer:
B) temporal summation
Explanation:
When two EPSPs occur at the same synapse, the process called temporal summation occurs.
Temporal summation is the process of combining the postsynaptic potentials of different neurons as they are added in sequence.
When occurring in rapid succession, the final potential becomes a cohesive sum of the postsynaptic potentials. Therefore, temporal summation can be defined as the sum that creates postsynaptic potentials at different times.
