The correct answer is (C) biomass at each trophic level
Pyramid of energy is a graphic representation of amount of energy trapped per unit time and area in different trophic levels of a food chain with producers forming the base and top carnivores the tip. As the biomass of producers are always greater than the carnivores, the pyramid of energy can't be inverted.
Answer:
of diffusion
Explanation:
Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.
<span> The Hardy- Weinberg theory states that frequencis of alleles and genotypes will remain constant from generations to generationss without the evolutionary influences. From your choices, the three supports the Hardy- Weinberg equilibrim but letter C does not. There must be no new allele to be produced fro the mutation of the pea plant.</span>
Answer:
Friction
Explanation:
Because the cow is walking
Answer:
Gamma-aminobutyric acid (GABA)
Explanation:
Epileptic seizures are induced by a preponderance of electrical activity within the network of neurons in the brain. Synapsis is the meeting point between the axon of one neuron and the dendrite of another neuron. Electrical signals don't cross through the synapsis, instead, they are conveyed in a chemical form by neurotransmitters.
The neurotransmitters convey messages across the synapsis in a chemical form until they find to the receptor of the dendrite of the receiving neuron. Neurotransmitters can either be excitatory or inhibitory in function i.e. the receiving neuron can either be stimulated to action or inhibited from action. The main excitatory and inhibitory neurotransmitters in the brain are Glutamate and Gamma-aminobutyric acid (GABA) respectively.
There must be a balance between excitation and inhibition of neurons, in order to ascertain the optimal functioning of the brain. Too much Glutamate or too little of GABA can make neurons hyperexcitable and hyperexcitability of neurons makes the brain susceptible to seizures.
