If I'm not mistaken, I believe the baby has a heart beat.
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
It’s between d and c but d sounds better
Options were missing from the question so the options are:
A.From the ice cube to the glass.
B. From the lemonade to the glass.
C. From the lemonade to the ice cube.
D. From the ice cube to the lemonade.
Answer: Option C
Explanation:
The main principle of heat transfer is that heat always flows from the hotter body to the colder body.
Here, the hotter body is thermos in which the lemonade was kept and the colder body is cooler in which the ice was kept.
During the mixing of lemonade into ice, the heat will from the hotter body to the colder body which means from lemonade to the ice. This process of heat transfer is unidirectional( hot body to cold body).
Hence, the correct answer is option C.
