Answer:
genetics i.e the law of heredity
Answer:Mendel proposed three laws: Law of Dominance. The Law of Segregation. Law of independent assortment.
Explanation:Gregor Johann Mendel was a scientist who is recognized as the Father and Founder of genetics. Mendel conducted many experiments on the pea plant (Pisum sativum) between 1856 and 1863. He studied the results of the experiments and deducted many observations. Thus, laws of inheritance or Mendel’s laws of inheritance came into existence. Before learning about Mendel’s laws of inheritance, it is important to understand what the experiments performed by Mendel were.

Calcium Carbonate decomposes at 1200°C to form carbon dioxide and
calcium oxide. If 25 L of carbon dioxide are collected at 1200°C, what will
the volume of this gas be after it cools to 25°C?
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]V_1 = 25 \ L[/tex][tex]T_1 = (1200+ 273 )K[/tex][tex]= 1473 \ K[/tex]
[tex]T_2 = (25+ 273)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]

When we look at heat transfer problems that include phase transitions, there can bemanynec-essary steps. Consider a material of massmthat undergoes two phase transitions: from solid toliquid and then from liquid to gas. It starts at an initial temperature ofT0(well below the meltingtemperature ofTm) and it heated until it is a gas at a temperature ofTf(well above the boilingtemperature ofTv). How many different steps (simple temperature changes or phase transitions)of heat transfer would you need for this problem
Answer:
There would be 3 temperature changes and 2 phase transitions
Explanation:
The temperature of the material would first increase from T0 to Tm (its melting point)- This is one temperature change.
It would the change from solid to liquid at its melting point Tm.- This is one phase transition.
Its temperature would then increase from its melting point Tm to its boiling point Tv -This is another temperature change.
It would then change from liquid to gas at its boiling point Tv - This is another phase transition.
Finally, its temperature would then increase from its boiling point to T(f) - This is the third temperature change.
So, there would be 3 temperature changes and 2 phase transitions

This gland of the endocrine and digestive systems produces insulin to help control the body's sugar levels and enzymes which aid in digestion.
Answer:
Pancreas.
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.

La capacidad calorífica del aluminio es de 0.9 J/g C. Determine la energía necesaria calentar un bloque de aluminio de 850 g de 22.8 grados a 94.6 grados Celcius.
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:
c= 0.9 [tex]\frac{J}{g*C}[/tex]m= 850 gΔT= Tfinal - Tinicial= 94.6 C - 22.8 C= 71.8 CReemplazando:
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.

Mass=
g give your answer to two significant figures.
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) =

What determines crystal size in minerals formed by lava or magma?
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.
