Ravi brushes his teeth 18 times a day. Each time, he uses exactly 83 strokes up and 83 strokes down. After he eats, he must brus
Bingel [31]

Based on the fact that Ravi has to brush a certain amount of times, he most likely suffers from obsessive-compulsive disorder.

<h3>What does obsessive-compulsive disorder lead to?</h3>

When a person has OCD, they will engage in repetitive actions because they believe that not doing so can lead to further problems.

Ravi therefore engages in the repetitive action of brushing a certain number of times, because if he doesn't do so, something bad might happen.

✔ WHAT NEW FEATURES HUMANITY PRESENTED? plissss
kiruha [24]

A los humanos se nos clasifica entre los hominoideos, donde se incluyen los llamados simios antropomorfos (de forma humana) como los chimpancés, los gorilas, los orangutanes y los gibones. De éstos, nuestros parientes más cercanos son los chimpancés, luego los gorilas, y mucho más alejados los orangutanes y gibones.

Pero a pesar de grandes semejanzas, los seres humanos tenemos características biológicas distintivas como el cerebro más grande y la postura erecta que nos permite caminar en dos extremidades; además, la cara plana debido a la reducción de los maxilares, el dedo pulgar oponible más largo (lo que permite mayores habilidades de manipulación como la escritura, el manejo de herramientas, etc.), reducción del vello y cambios en las glándulas de la piel, ovulación críptica (que pasa desapercibida), desarrollo lento, inteligencia (pensamiento abstracto, categorización y razonamiento) y habilidad para hablar más desarrolladas, así como el uso, control y modificación del entorno.

También se nos distingue de nuestros antepasados directos por diferencias no biológicas a las que podemos llamar culturales, y que son típicamente humanas, como la fabricación de herramientas, el lenguaje simbólico, el saber que nos vamos a morir algún día, una organización social basada en la división del trabajo, el desarrollo de una capacidad moral y el establecimiento de relaciones afectivas más profundas y variadas. La cultura es una característica que incluye también a las instituciones políticas y sociales, al arte, la ciencia y la literatura, y en general todas las creaciones de la mente humana

Understanding that although the shape of an object may change, the mass of the object stays the same is an example of
CaHeK987 [17]

Answer:

C. Conservation

Explanation:

Mass is defined as "the amount of matter held within a body and hence stays the same, irrespective of our location, since the amount of matter will stay fixed"

The mass is a property that never change no matter the place, ambiental conditions, temperature and other possible factors.

The only possibility in order to change the mass is with chemical reactions or desintegration processes but that's very improbable. So for this reason this is an example of conservation.
