A food chain can usually sustain no more than six energy transfers before all the energy is used up. And so less energy is transferred at each level of the food chain so the biomass gets smaller.
Answer:
The answer of ist question FADH2,NADH 2nd question O2 3rd question NAD+,FAD,H2O,ATP.
Explanation:
Ist answer
During electron transport chain electrons are donated by reduced coenzymes such as NADH and FADH2.
2nd answer
During electron transport chain oxygen or O2 act as terminal electron acceptor which accepts and then undergo reduction to generate H2O.
3rd answer
The final products of electron transport chain and oxidative phosphorylation are NAD+, FAD,H2O and ATP.
Answer:
The function of the central nervous system is to control all function of the body and mind and to integrate all sensory information received and and respond accordingly.
The central nervous system is made up of the brain and the spinal cord and its neurons.
The resting state of a neuron is -70 mV (mV=millivolt) - which means that the inside of the neuron is 70 mV less than the outside of the neuron, therefore, at rest, there are relatively more sodium ions outside the neuron (which are negatively charged) and more potassium ions inside that neuron (Positive charge)
Active transport requires energy, whereas passive doesn't.
Both Endocytosis and Exocytosis are transports that require energy from the cell in order to transport particles. Therefore, they're forms of active transport.
