¿Qué importancia tiene el saber sobre las propiedades de la energía?
user100 [1]
En qué medida todos los objetos con los que interactuamos (comida, bebida, mesas, sillas, coches, ordenadores ...) están hechos de materia: es importante conocer las propiedades que encontramos en nuestra vida diaria para poder interactuar con ellos . es decir. por lo que no tratamos de beber sólidos, necesitamos conocer la propiedad del material "fase" como sólido líquido o gas y cómo diferenciarlos. Eso es solo un ejemplo muy simple. La gente siempre se quema, por ejemplo, cuando era evitable, porque no entendió alguna propiedad de la materia que se enseña en la escuela. Saber cómo surgen las diversas propiedades de la materia es importante porque no podemos predecir qué propiedades serán importantes en el futuro y así es como se puede anticipar de manera más confiable cómo se comportarán los objetos. De esa manera, estará mejor equipado para lidiar con asuntos que no haya encontrado anteriormente. Es por eso que se enseñan propiedades que es poco probable que encuentre en su vida diaria, al menos no directamente. Además, el hecho de que nunca se encuentre con una propiedad en particular no significa que no sea importante conocerla. Otras personas ... con las que interactúas, es decir. es posible que tenga que votar sobre algo que se base en una explicación basada. Además, yo diría que nuestras vidas son más ricas si sabemos lo que realmente está sucediendo. 21K vistas Ver votos positivos. -Simon bridge

Urgent please and thank you
BabaBlast [244]

Answer:

1. C

2. All cells of your body have the same DNA/genetic information but cell differentiation causes some genes to turn off and some to turn off. The activated genes are coded for which produce proteins and amino acids allowing cells to differentiate. E.g. Neurons and epithelial cell have same genetic information, however the genes coding for neurons in epithelial cells are turned off or deactivated which make them epithelial cells

How would I explain it?
Zina [86]

Answer:

What would explain the change in reaction rate —degradation of cellulose by the enzyme cellulase—after 75 minutes is the depletion of the substrate on which the enzyme must act.

Explanation:

A chemical enzymatic reaction, such as cellulase degradation of cellulose, occurs until the substrate is consumed.

The solution to which cellulase is added has the same concentration of cellulose, and what is done is to add enzyme. In the graph you can see that the reaction takes place over time, decreasing the amount of glucose obtained. From 75 minutes onwards the reaction rate decreases as well as the amount of glucose obtained from the reaction, which is due to the fact that the substrate —cellulose— is being depleted.

Hypothesis: If i add the egg to vinegar then the shell will dissolve within 24 hours
nadezda [96]

Answer :

Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell.  The calcium carbonate shell gets dissolve.

Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.

When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.

Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.
