Because neurones will not function properly neither will neuroreceptors if a person lacks neurotransmitters, these two parts (transmiters and receptors) all work together and depend on eachother.
Neurones are resposible for transmitting informations trought the body, and if neurotransmitters are no-existent, information may not be able to get to some body parts since neurotransmitters transmit the information.
Hope it helped,
Happy homework/ study/ exam!
If there is limited of food then they will compete but if there is an equal amount of food they won’t compete. So the answer is true.
The hypothalamus in the brain contributes to the body's maintenance of a steady internal physiological state, called homeostasis.
I believe that the correct match will be;
Prominences- A
Sunspots - B
Solar flares - C
Convection -D
Prominence is a large, bright feature extending outward from the Sun's surface. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's hot outer atmosphere, called the corona.
Sunspots are darker, cooler areas on the surface of the sun in a region called the protosphere. Solar flares are large eruptions of electromagnetic radiation from the sun lasting from minutes to hours.
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.
