A phospholipid is the macromolecule that forms the phospolipid bilayer of the cell membrane. A phospholipid is contained of two fatty acids. They form a bilayer that is hydrophobic on one side and hydrophillic on the other.
Answer:Without leaves green plants could not live.
Explanation:because from leaves a plant take breath or do respiration. In leaves of plants there are small pores or stomata from where they breathe. So if we can't breathe we can't live.so,Without leaves green plants could not live.
<h2>The Cardiac cycle</h2>
Explanation:
Correct order is: 3,5,6,4,2,1,8,7
The cycle of events that happen in a single heart beat is called Cardiac cycle. Basically, it refers to repeated pattern of contraction and relaxation of the heart.The contraction of heart is called systole and the relaxation of heart is called diastole. The cardiac cycle includes systole and diastole of atria as well as systole and diastole of the ventricles. When heart rate is about 75 beats per minute, a cardiac cycle takes 0.8 seconds.
The order of events is cardiac cycle is :
- beginning of atrial systole
- completion of ventricular filling.
- beginning of ventricular systole.
- closure of AV valve.
- isovolumic contraction.
- opening of semilunar valve.
- ventricular ejection.
- ventricular relaxation.
Answer:
Both aristotle and ptolemy models stated that the planets rotate on their axis. Both models stated that the planets and objects in the solar system have small orbits called epicycles. The both persons are stated that the sun is the center of the system around which objects have elliptical orbits.
