La hipótesis señalan las relaciones o vinculos existentes entre las variables y cuales de ellas se debe estudiar sugiriendo una explicación en ciertos hechos y establecer como se debe organizar el análisis de los datos. Las observaciones es el método para reunir información visual sobre lo que ocurre o como se comporta el objetivo
Answer:
The correct answer is - 0 m/s.
Explanation:
In this position-time graph or distance-time graph, there are three different part that shows three different velocities one in increasing as it moves from a lower position in relative to time and one is stationary and the third is decreasing.
'Straight lines' on a distance-time graph suggest that the movement of the object is constant. During 'Part B' of the journey the object travels 0m in 3s. It is stationary for 3 seconds so the velocity will be zero as well.
The correct answer is detailed structure inside the cell.
The main feature of compound light microscope is the light source which helps to see the objects more clearly. This microscope is usually used to see the detailed structure inside the cell. The cell organelles are clearly visible that are very minute in size and cannot be seen through naked eyes. This allows us to study the features of the cell more accurately and precisely.
Cocaine induces a sense of exhilaration by increasing the availability of dopamine and serotonin in synapses. Cocaine is among the powerful stimulants which increase the release of neurotransmitters such as nor-epinephrine, dopamine and serotonin, that affect CNS and PNS activity. Cocaine administration constricts blood vessels that are absorbing it, son snorting it is a slow way to deliver it to blood stream and eventually the brain.
