gladu [14]

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.

List the three laws of Newton in your words. Give an example of each.
OLga [1]

1. For every action there is an equal and opposite reaction

2. Force = mass times acceleration

3. An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted on by another force.

3. One example is a rock rolling down a hill. You could use a stick or your foot to stop it, but otherwise it would keep rolling

2. An example for law No.2 is pushing a shopping cart. If you push an empty shopping cart, it will go faster than a full shopping cart because the full shopping cart has more mass.

1. One example is a cup on a table. The cup exerts a force down on the table due to gravity, the table exerts an equal and opposite force on the cup to stop it falling through the table

Birds have been observed puffing
Vlad1618 [11]
It's an important part of the bird's ability to maintain its body temperature. 
Air is a poor conductor of heat, so the air trapped among the feathers
prevents the loss of heat in cold atmosphere, and prevents overheating
in hot atmosphere.  Much like our wearing several layers of clothing.
