The light reactions use the reactant water from the equation and release the product oxygen.
Answer:
Energy
Explanation:
An energy pyramid shows the amount of energy available at each feeding level in an ecosystem.
Osmosis. This<span> is the procedure in which water absorption through semi permeable membranes happens at high concentration levels. Semi permeable membranes pertain to tissues found in the plant roots; from there, water will be transported to an area with much lower concentration levels</span>
Answer:
The correct answer will be option-D.
Explanation:
Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.
Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.
This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.
Thus, option-D is the correct answer.
1- they can be used as domestic fuel for cooking instead of kerosene or firewood that contribute to pollution
2-they can also used to generate electricity in rural areas as these areas has not enough resources of electricity
