What are abiotic factors? 
The definition of abiotic Is a non living part of the ecosystem that make up our environment   for example Water and light!All of these factors work together to make up what we have today!
 Why are they important?
They are important because with out these we would not be living because for example water is a abiotic factor and we can't live with out water!
Hope this helps!

The sickness can originate from her predecessors, it's as of now in her qualities. Expires don't have anything to do with races. 
Race and wellbeing allude to the connection between singular wellbeing and one's race and ethnicity. Contrasts in wellbeing status, wellbeing results, future, and numerous different markers of wellbeing in various racial and ethnic gatherings is all around recorded, alluded to as wellbeing abberations. The race is an intricate idea, and the two noteworthy contending speculations of race utilize organic definitions and social development to characterize the racial distinction.
        
             
        
        
        
If the researchers replaced the bacterial proton pump with a proton pump that was activated only by atp then less ATP would be produced when the light is on because no proton gradient would be available to produce ATP.
<h3>What is 
proton gradient ?</h3>
Two quinol (4H+4e) oxidations at the Qo site result in the formation of one quinol (2H+2e) at the Qi site, creating a proton gradient (in total six protons are translocated: two protons reduce quinone to quinol and four protons are released from two ubiquinol molecules).
For the ETC to continue functioning, the energy trapped in the electrochemical gradient of protons across the inner mitochondrial membrane must also be released in some manner. ATP is created using the energy in the proton electrochemical gradient.
Chemiosmotic coupling is the process by which ATP synthesis is coupled to the electrochemical gradient of H+ across the inner mitochondrial membrane.
Peter Mitchell, who in 1961 made the initial suggestion, was given the Nobel Prize for his efforts in 1978.

The given question is incomplete as it does not have the options which are:
a) Sensory receptor
b) Sensory neuron
c) Motor neuron
d) Effector
e) Integration center
Answer:
The correct answer is option-Effector
Explanation:
A reflex arc is the mechanism of the neurons which controls the reflex action or involuntary responses or the instantaneous responses of the organisms.
The reflex arc involves the sensory receptors, sensory neurons (transmit signals from sense organ to spinal cord), motor neurons (transmit signals from spinal cord to muscle), Integration centre in the spinal cord and effector.
An effector represents the gland or the muscle which receives the transmitted signal from the motor neuron and responds by showing movements.
Thus, option-Effector is the correct answer.
