Do a cross graph with B and W
Answer:
The correct answer is chemical energy from broken bonds is transformed into mechanical energy.
Explanation:
Muscle contraction need energy in form of ATP.ATP contain 2 high energized phosphoanhydride bonds.
The hydrolysis of phosphoanhydride bonds releases chemical energy which is transformed into mechanical energy for helping the muscles to move.
<span>Phospholipids are the most abundant lipid in the plasma membrane. Phospholipids are amphipathic molecules, containing hydrophobic and hydrophilic regions. The fluid mosaic model states that a membrane is a fluid structure with a mosaic of various proteins embedded in it.</span>
The answer is (D.) 225, 000, 000 km
AU means astronomical unit. It is used by the astronomers to measure large distances in the Solar System. 1 AU is the average distance from Sun to Earth which is 149, 598, 000 km.
So to get the km value of 1.5 AU.
1.5 x 149, 598, 000 = 224, 397, 000
Round off to 225, 000, 000
The answer is B. Natural Selection
