Facilitates the roots of plants going down towards gravity and the stems to rise up away from gravity. ... Thus, the difference is that geotropism is driven by gravity and phototropism is driven by light.
So basically water is a polar molicule. So when it comes to the structure, water is able to form many hydrogen bonds and the way the atoms are able to bond together adds to the water's special properties.
The energy released is used for assembly of actin filament with myosin head. when myosin is attached to ATP its heads cannot bind to actin and therefore muscle will remain in relaxed form. However during muscle contraction an enzyme referred to as ATPase hydrolyses ATP to ADP and organic phosphate in the process releasing energy. The energy released changes the position of head of myosin which facilatate its binding with actin. Myosin moves towards m-line dragging actin along with it reducing the length of sarcomere leading to muscle contraction.
ATP, NADPH, and oxygen are formed products of the light-dependent portion. The independent part would produce things like glucose or lowered amounts of energy and NADP, much lower.
Answer: Option B
Pigs wallow in the mud to cool themselves down.
Explanation: Pigs' skin contains lots of fats, and fats serves as thermal insulator during cold (low temperatures); unfortunately, this feature turns becomes a disadvantage during heat (high temperatures). Hence, pigs frequently wallows in the mud (or any nearby cool water place) - to reduce their body temperature.
