Answer:

I believe it is 3. All of these.

Explanation:

Not all organisms hold their genetic code (DNA) inside a nucleus. In fact, some organisms don't have a nucleus at all but I'm pretty sure that these three do. I would select all of these.

Hope that helps and have a nice day.

Answer:

When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

Answer:

Spring

Explanation:

Spring is a place where water moving underground finds an opening to the land surface and emerges, sometimes as just a trickle, maybe only after a rain, and sometimes in a continuous flow. ... Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human interference.

This is a Charles' Law problem: V1/T1 = V2/T2. As the temperature of a fixed mass of gas decreases at a constant pressure, the volume of the gas should also decrease proportionally.

To use Charles' Law, the temperature must be in Kelvin (x °C = x + 273.15 K). We want to solve Charles' Law for V2, which we can obtain by rearranging the equation into V2 = V1T2/T1. Given V1 = 25 L, T1 = 1200 °C (1473.15 K), and T2 = 25 °C (298.15 K):

V2 = (25 L)(298.15 K)/(1473.15 K) = 5.1 L.  

The volume of this gas will be "5.1 L".

Given:

             [tex]= 1473 \ K[/tex]

             [tex]= 298 \ K[/tex]

As we know,

→ [tex]\frac{V_1}{V_2} = \frac{T_1}{T_2}[/tex]

By substituting the values, we get

→ [tex]\frac{25 \ L}{V_2} = \frac{1473 \ K}{293 \ K}[/tex]

→    [tex]V_2 = \frac{25\times 298}{1473} \ L[/tex]

→         [tex]= 5.1 \ L[/tex]

Explanation:

Living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.

An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.

Pancreas is one of the glands of the endocrine and digestive systems that produces insulin to help control the body's sugar levels and enzymes which aid in digestion.

Answer:

La energía necesaria para calentar el bloque de aluminio es 54927 J.

Explanation:

Se denomina calorimetría a la medición y el cálculo de las cantidades de calor que intercambia un cuerpo o un sistema.

De esta manera, entre el calor y la temperatura existe una relación de proporcionalidad directa (Dos magnitudes son directamente proporcionales cuando existe una constante de manera que cuando una de las magnitudes aumenta, la otra también; y lo mismo ocurre cuando alguna de las dos disminuye.). La constante de proporcionalidad depende de la sustancia que constituye el cuerpo como de su masa, y resulta el producto del calor específico por la masa del cuerpo. Entonces, la ecuación que permite calcular intercambios de calor es:

Q=c*m*ΔT

Donde Q es el calor intercambiado por un cuerpo de masa m, constituido por una sustancia de calor específico c y donde ΔT es la variación de temperatura.

En este caso:

Reemplazando:

Q= 0.9 [tex]\frac{J}{g*C}[/tex]*850 g* 71.8  C

y resolviendo se obtiene:

Q= 54927 J

La energía necesaria para calentar el bloque de aluminio es 54927 J.

Explanation:

Weak acids dissociate only slightly in an aqueous solution. The majority of molecules remain undissociated.

You know the number of moles of Mg that react: 6 moles.

You don't know (yet) how many moles of Mg₃N₂ are produced when 6 moles of Mg react.

The coefficients of each substance in the chemical equation tells us the molar ratio between the substances. The coefficient of Mg is 3, and the coefficient of Mg₃N₂ is 1 (coefficients of 1 are implied and omitted). So, for every 3 moles of Mg that react, 1 mole of Mg₃N₂ is produced.

We can use the proportion set up in the image to calculate the number of moles of Mg₃N₂ produced. In the first fraction, the green-boxed numerator should be our known number of moles of Mg, that is, 6 moles Mg. In the second fraction, we insert our molar ratio. Since we want the product of these two fractions to have the units "moles Mg₃N₂," the numerator in the second fraction should be 1 mole Mg₃N₂ and the denominator should be 3 moles Mg.

Our setup should look like this:

[tex]\frac{\textrm{6 moles Mg}}{1} \times \frac{\textrm{1 mole }\mathrm{Mg_3N_2}}{{\textrm{3 moles Mg}}} = \textrm{2 moles }\mathrm{Mg_3N_2}.[/tex]

Indeed, 2 moles of Mg₃N₂ are produced.

Answer:

2 moles of Mg₃N₂ are produced.

Answer:

60g

Explanation:

The molar mass of a substance (Atom or molecule) is defined as the mass in grams that 1 mole of substance (6x10²³ particles of this substance) weighs. Using the periodic table of elements we can know the molar mass of each atom.

For example, the molar mass of Calcium is 40.078g / mol.

That means the mass of 1.5 moles of calcium atoms must be:

1.5 moles * (40.078g / mol) =
