its true please mark me as brainliest i need it.
Answer:
Passive transport.
Explanation:
The transport of molecules across the plasma membrane can occur by the two process- active transport and passive transport. No amount of energy is required during the active transport.
Passive transport includes the diffusion and osmosis. Both the diffusion and osmosis do not require energy and the molecules move down from the region of higher concentration towards the region of lower concentration. Small molecules, ions and proteins can go through the passive transport.
Thus, the correct answer is option (c).
Answer:
The energy used for muscular cont ration is ATP(adenosine triphosphate) This is the energy currency produced in the mitochondrial during cellular respiration.
During muscles contraction.The ATPs is broken down to ADP and Pi.
This is the breakdown of energy rich bonds binding phosphate ions with ATP.The breakdown of the bonds produced -32kJper the 3 bonds in ATP. Therefore as each bond is broken, energy is produced for muscle contraction
It is an exergonic reaction with production of heat.
Thus ATP is used for muscle contraction.ADP is the intermediate of ATP when one Phosphate is removed during the breakdown.
Thus the sequence is Adenosine triphosphate (3 phosphate) to Adenosine diphosphate(2 phosphate) to Adenosine monophosphate (1 phosphate)
Each bond breakin gives equal energy of -32kJpermol.

Explanation:
In observing, we have our 5 senses (smell, taste, touch, see, hear) meaning scientists uses their 5 senses to be able to have a prediction or a hypothesis about the problem.
