Darwin's theory of Natural Selection
Explanation:
the answer is C cardiac muscle I'm pretty sure this is the correct answer
Answer:
(d) Electrical-->Chemical-->Electrical
Explanation:
A nerve impulse is the transmission of an electrical change along the neuron's membrane from the point at which it is stimulated (synapse). The normal direction of impulse in the body is from the cell body to the axon. This nerve impulse, or action potential, is a sudden and rapid change in the transmembrane potential difference.
Normally, the membrane of the neuron is polarized at rest, which means that the ionic constitution of the medium internal to the membrane is different from the external medium, which generates different electrical charges in one medium and the other, so this difference, ie , the potential during rest is negative (-70 mV). The action potential thus consists of a rapid reduction of membrane negativity to 0mV and inversion of this potential to about + 30mV, followed by a rapid return to values slightly more negative than the resting potential of -70mV.
Nervous impulse or action potential, therefore, is a phenomenon of an electrochemical nature and occurs due to changes in the permeability of the neuron membrane. These permeability modifications allow ions to pass across the membrane. Since ions are electrically charged particles, changes also occur in the electric field generated by these charges.
Thus, we can say that the correct answer to this question is: Electrical -> Chemistry -> Electrical
Answer:
Explanation:
Think about what a school would have/use that has the most environmental impacts. I think of energy and waste from trash. To counteract these they could install a cleaner method of getting energy like solar panels and for the trash they could implement a recycling program
Answer:
Ambitious
If your body lacks enzymes that break down
carbohydrates, it would be unable to get sugar molecules for energy production.
If you lacked the enzyme to digest proteins, you may not absorb enough amino
acids.
The digestive system in our body changes
carbohydrates into glucose; also known as blood sugar to be use as an important
source of energy. Meanwhile, amino acids are organic compounds that combine to
form proteins, which are the building blocks of life.
