Is there more for the question? Just because it has the prices there is still nothing about the amount.
Answer:
Steroid; is a component of eukaryotic membranes.
Explanation:
Cholesterol is one of the most important chemical synthesized by all the animals. The chemical formula of cholesterol is C27H46O. The cholesterol in solid state was first given by C27H46O.
Cholesterol is present in the plasma membrane and maintain its membrane fluidity. Cholesterol is an important structure of the plasma membrane and acts as a pre cursor for various hormone. The cholesterol is a type of sterol and a lipid.
Thus, the correct answer is option (1).
Normal polarity
Explanation:
Earth's magnetic field used to be twice as strong 1.5 billion years ago as it is today and Earth's temperature other than what the geologists see from the 'normal' pattern. It has been noticed that some volcanic rocks were magnetized in opposite direction to the direction of the local Earth's field. It is clear that the Earth has experienced the normal polarity 1.5 years ago but at that time, the Earth's polarity was poorly understood.
D) orbit the nucleus like the planets orbit the sun.
this idea was first proposed in the rutherford model:)
