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
One negative side effect of with anaerobic synthesis of energy is that a by product of glycolysis is lactic acid
lactic acid cause muscle fatigue and post exercise muscle soreness. when you exercise the body uses oxygen to break down glucose for energy. when one do intensive exercise, oxygen may not be enough therefore lactic acid is produced.
Answer: One thing that is NOT true that concerns conifers is <u>they have motile sperm. </u>
Explanation:
Conifers are a seed plant. They are usually trees that bear cones and they have vascular tissues. They are classified as gymnosperms. The living confers are all woody plants.
The trees that are conifers are;
- Junipers
- Cedars
- Cypresses
- Firs
- Kauris
- Redwoods
- Spruces
- Yews
The colors of these conifers vary and include colors such as rainbow, bronze, yellow, blue, and red.
