Answer:

Plants absorb nitrogen from: the soil ( second choice)

Sphinxa [80]3 years ago

<u>ANSWER:</u>

Plants absorb nitrogen from the soil.

<u>EXPLANATION:</u>

  • Nitrogen is absorbed by the roots of the plants in the form of amino acids, nitrate or nitrite ions.  
  • The nitrogen absorbed from the soil by roots is then transported to the various parts of the plants. Plants do not get nitrogen they need directly from the air.
  • This is because the organic nitrogen that is available in the atmosphere is not usable for plants. Plants need non-organic nitrogen which is obtained by changing organic nitrogen into non-organic forms by the bacteria in the soil.

tino4ka555 [31]

La respuesta correcta para esta pregunta abierta es la siguiente.

Los tres avances científicos más importantes, a través de la historia para la humanidad son los siguientes.

1.- El descubrimiento de la penicilina.

El científico Inglés Alexander Fleming fue el descubridor de la penicilina en septiembre de 1928. Este descubrimiento revolucionó la historia de la humanidad.. Antes, millones de personas morían debido a las infecciones en el cuerpo humano. La penicilina resultó ser el antibiótico más efectivo descubierto hasta el día de hoy y ha salvado millones de vidas humanas desde su descubrimiento.

2.- El descubrimiento de la electricidad.

¿Te puedes imaginar un día de tu vida sin luz?

Bueno, pues así vivió la gente toda la vida hasta el siglo XVIII, cuando comenzó a entenderse y desarrollar mejores maneras de producir electricidad. Prácticamente todos los aparatos electrodomésticos, de laboratorio, hospitales, en oficinas, escuelas y demás, funcionan con electricidad. Sin ella, nuestra vida no habría producido los avances que conocemos el día de hoy.

3.- El internet.

La revolución de este siglo.

El internet nos mantiene conectados todo el tiempo a cualquier parte del mundo. Con el internet podemos hacer miles de cosas desde nuestras computadoras y teléfonos celulares, que hasta hace 15 años eran inimaginable.

A systematic process is usually intimately connected with the decisive study. In common, the purpose of a systematic process is viewed as a mechanism of control directed at decreasing the number and austerity of errors, omissions, and failures due to both human or technological functions associated.

Gold has a specific heat of 0.129 J/(g×°C). How many joules of heat energy are required to raise the temperature of 15 grams of
Elodia [21]

Answer:

\boxed {\boxed {\sf 121.905 \ J  }}

Explanation:

We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;

q= mc \Delta T

The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.

  • ΔT= final temperature - initial temperature
  • ΔT= 85 °C- 22°C = 63°C

Now we know all the values:

m= 15 \ g \ \\c= 0.129 \ J / (g* \textdegree C) \\\Delta T= 63 \ \textdegree C

Substitue the values into the formula.

q= (15 \ g)( 0.129 \ J / (g* \textdegree C)) ( 63 \ \textdegree C)

Multiply the first numbers together. The grams will cancel.

q= (1.935 \ J/ \textdegree C) ( 63 \ \textdegree C)

Multiply again, this time the degrees Celsius cancels.

q= 121.905 \ J

<u>121.905 Joules</u> are required.

trapecia [35]

Answer:

Los gases que tienen huellas de carbono son dióxido de carbono, monóxido de carbono y gases de metano, etc.

Explicación:

Los gases contaminados que contienen huellas de carbono son dióxido de carbono, monóxido de carbono y metano, etc. Estos gases tienen un efecto negativo sobre el medio ambiente porque son responsables del calentamiento global de la atmósfera y disminuyen la calidad del aire que produce muchas enfermedades nocivas. Las principales causas de la emisión de gases contaminados son las actividades humanas como la quema de combustibles fósiles y el humo que producen las industrias, etc.
