Answer:
Drogas.
Explanation:
Las drogas son sustancias que tienen un efecto modificatorio sobre el estado normal de la psique. Por tanto, estas sustancias influyen en el comportamiento o la experiencia del usuario, pudiendo tener un efecto alucinógeno, pero también sedantes o una mixtura entre ambos.
El término se usa generalmente para indicar sustancias que tienen un efecto muy fuerte (por ejemplo, heroína, cannabis, mescalina, alcohol). Aunque los estimulantes cotidianos como el café y el chocolate también pueden tener un efecto en la psique, generalmente no se clasifican como sustancias psicoactivas debido a su efecto relativamente leve.
Los medicamentos que tienen un efecto sobre la psique se denominan psicofármacos. No obstante, los medicamentos que no se clasifican principalmente como psicofármacos, como los antihistamínicos, los agentes anti-mareo y los betabloqueantes, pueden también tener un efecto psicotrópico.
Answer - It defines how much a cell can do metabolic exchange and chemical substance exchange.
Reasoning - A Cell that is large has the ability of inadequate to provide the cell its nutrients and metabolic needs for the exchange in chemical substances.
Whereas a small cell does not take up space and can exchange quicker with chemical substance and nutrients because of its size to the surface area.
Answer:
Force of gravity!
Explanation:
The reason I say this is because a "dependant varible" is a variable that is being measured in a science experiment. Even though potential energy could be the answer it isn't because in this experiment the kinetic and potential energy are being measured. Depending on the height of the ball on the ramp the force of gravity will depict whether it goes faster and longer.
Hope This Helps :)
<u>Answer</u>:
An observation that would allow for identification of the cell as an animal cell rather than a plant cell would be "the centrioles migrating".
<u>Explanation</u>:
Centrioles start moving towards the opposite ends of the cell, whereas the microtubules starts moving from the centrioles and gets attached to the centromeres of chromosomes. The microtubules that have been projecting from the centrioles on opposite poles of the cell are connected to individual centromere and further form into spindle fibers. After the accumulation of chromatin into chromosomes in prophase, resulting in the breaking down of the nuclear envelope, or membrane. In case of animal cells, the centrioles present at the nucleus starts to separate and go to the opposite poles of the cell. As the centrioles transfer, a spindle is seen to be formed between them.
