Answer:
d. Opening of voltage gated calcium channels in dentate gyrus axons, fusion of glutamate containing vesicles to the presynaptic membrane, opening of AMPA receptors in CA3 neuron dendrites, sodium influx into CA3 neurons.
Explanation:
From the little information given above in the excerpts, it could be seen that, the sequence of events that would occur when the mossy fiber is stimulated with an extremely strong stimulus is what was given above.
Answer:
8 min 20 seconds
Explanation:
Radiation from the sun travels as light through the vacuum of space. Therefore, it is travelling at the speed of light which is roughly 300,000 km/s. If we divide this speed by the average distance between the Sun and the Earth (150,000,000 km) we would get a total of 500 seconds. We can now turn this total time into minutes which would be roughly 8 min and 20 seconds. Therefore, it would take a total of 8 min 20 seconds for radiation from the Sun to reach Earth.
They are considered hypotheses for a few reasons : Evolution of organisms has been occurring for hundreds of thousands of years.Since no one has actually been around that long to observe exactly what happened, phylogenetic trees are based off of 'clues' we have such as the fossil record and mutations in mitochondrial DNA. Therefore the 'proof' we use to make phylogenetic trees is not necessarily solid 'proof' but is instead facts put together through strong correlations.
Answer:
The Product
Explanation:
In a chemical reaction the enzyme plays an important role in catalyzing the reaction.
The enzyme has an active site on its structure to which a substrate can come and bind. The active site has a specific shape to which the substrate of complementary shape can come and bind. once the substrate is bound to the active site of the enzyme the reaction takes place and a product is formed. Once the product is formed, product is released from the active site and enzyme remains unchanged at the end of the reaction.
therefore answer is product that is released from the active site
The monomers of nucleic acids are B. Nucleotides.
