The answer is; hydrophilic heads; hydrophobic tails
The hydrophilic heads of a phospholipid are composed of a phosphate and glycerol molecule. Since the phosphate has a charge, the head are able to interact with water molecules through hydrogen bonds (Remember water is a polar molecule). The hydrophobic tails are composed of hydrocarbon chains that are uncharged hence do not interact with water. When phospholipids are immersed in water, they form a bilipid layer - with the hydrophobic tails clumped up together in the center and the hydrophilic heads on the outside.
Answer:
I am 100% sure that this answer is gonna be Gravity because the distance and mass are the two things that can differ the "force" of one thing...Gravity.
Explanation:
Answer:
Yes. So are earthquakes and volcanoes.
Explanation:
It's quite difficult to give you the ansver without any diagram attached. But I think I can help you. I suppose the first, the second and the third atom all are <span>carbon, Then fourth should be sulphur and the last one - nidrogen
The actual look of this task should be like that : </span><span>atom 1,2,3,4-sp2
atom 5-sp3. I hope it will help you in some measure, but next time check it carefully.</span>
When sarcomeres shorten, the muscle fiber SHORTENS.
Mechanism :
Sacromeres are used to construct the myofibrils, which are a part of the skeletal muscles of animals. They use the sliding filament model to carry out the muscle contraction and relaxation.
To create movement, The cross-bridge between actin and the myosin heads causes the sacromere to shorten. Muscle fibers contract as a result of this shortening of the sacromere, which has the overall effect of shortening the fibers.
