I was interested in science when I first saw a diagram of Solar system in my sister's geography book. At that time I was in Senior Kindergarten and she was in 6th grade. At first, I was just interested in space, universe and black holes stuff, but then as I started learning more, I realised how amazing other branches of science are too. They are so systematic. What encourages me to learn more are the gaps in science, its mysteries, I wish to uncover them one day, and for that I am preparing myself. When I am in a science class, I try to imagine where can I apply this knowledge in my day to day life, and my teachers are fascinated when I ask them if this principle is responsible for this phenomena. I love it very much. I like Physics the most, but other branches are great too.

One way of producing drinking water from seawater is by reverse osmosis.
Reverse osmosis is a type of filtration. Seawater is pushed through a semi-permeable membrane. Pressure is applied to the seawater. Semi-permeable
means salt is trapped on one side of the membrane, but water can pass through.
The trapped salts form a ‘seawater concentrate’ on one side of the membrane.
Where do the trapped salts go?

If oxygen causes fire to burn, why didn't the world explode when fire burns at a particular place...since oxygen is everywhere...? Explain...​

Answers

Answer:

Oxygen does not burn. It is not flammable, but it is an oxidizer.

Explanation

I think you are misunderstanding what is meant by "fire burns up air". Fire does use oxygen when it burns. But it also produces carbon dioxide. An oxygen molecule has two oxygen atoms in it. Fires use this to produce carbon dioxide by adding a single carbon atom from the fire’s fuel (wood, for instance).

Under certain conditions, the substance mercury(II) oxide can be broken down to form mercury and oxygen. If 24.1 grams of mercury(II) oxide react to form 22.3 grams of mercury, how many grams of oxygen must simultaneously be formed? Grams oxygen

Answers

Answer:

1.76 g

Explanation:

2HgO(s) ==> 2Hg(l) + O2(g)

Number of moles of Hg = 22.3 g/ 201g/mol

= 0.11 moles

From the reaction equation;

2 moles of Hg is formed alongside 1 mole of oxygen

Hence;

0.11 moles of Hg forms 0.11 moles × 1/2

= 0.055 moles of oxygen

Mass of oxygen formed = 0.055 moles of oxygen × 32g/mol = 1.76 g

El genotipo es el conjunto de información genética en un organismo, y se encuentra codificado en el ADN en su secuencia de bases. Dicha información se expresa mediante síntesis de proteínas.

1.  Los genes son unidades de herencia​ pues almacenan la información genética. El conjunto de genes de una especie se denomina genoma. Cada gen ocupa en el cromosoma una determinada posición, denominada locus. Para cada locus hay dos tipos o formas de genes, llamados alelos. Los mismos pueden ser iguales (siendo el organismo homocigota para ese locus) o distintos (heterocigota). Entonces, la respuesta es "b: Verdadero"

2. Los alelos dominantes, se representan con letras mayúsculas mientras que los alelos recesivos se representan con letras minúsculas. Ejemplo, el alelo que codifica para el color de ojos marrones puede ser dominante (se puede representar con la letra A, por ejemplo), mientras que el alelo que codifica para ojos verdes puede ser recesivo (a). Un individuo cuyo genotipo es Aa, tendrá ojos marrones ya que el alelo dominante enmascara los efectos del alelo recesivo. Un individuo AA también tendrá ojos marrones pues es el único alelo presente. Sin embargo, un individuo aa tendrá ojos verdes ya que tiene ambos alelos recesivos que se expresan. Entonces, la respuesta es "a: Falso"

3. Un cuadro de Punnett es un diagrama utilizado para determinar la probabilidad de obtener descendencia con un determinado fenotipo (características visibles) y genotipo (conjunto de genes). Permite utilizar genotipos maternos y paternos con sus alelos dominantes y recesivos , para cruzarlos y realizar el análisis. Entonces, la respuesta es "b: Verdadero"

4. Mendel realizó un experimento para estudiar los genes de la planta de guisantes. Cruzó una plantas de dos variedades distintas (gigantes y enanas), espolvoreando el polen de una sobre el pistilo de otra. Observó que en la primera generación de descendencia, habían todas plantas gigantes y no de tamaño "intermedio" Luego de esto, entendió que había una característica dominante para el tamaño gigante de una planta, y una recesivo para el tamaño enano. Pero previamente a todo esto, no conocía la dominancia ni el genotipo de los progenitores. Entonces, la respuesta es "a: Falso"

5. Una mutación es una alteración azarosa o por acción de un mutágeno en el ADN, ya sea en su secuencia de bases o en su organización. Esto hace que se produzca una variación en las características del organismo, que puede o no transmitirse a una descendencia. Una mutación genética hereditaria ocurre en las gametas femeninas (óvulo) y/o masculinas (espermatozoide). Cuando ocurre la fertilización, se crea un cigoto que dará lugar a un nuevo organismo que portará la mutación. Entonces, la respuesta es "b: Verdadero"

1. Cruce entre Aa x Aa

siendo A: verde, a: rojo

Cada genotipo, en este caso ambos Aa, representa los genes de un organismo. Sin embargo, en el cuadro de Punnett, se utilizan las gametas producidas por los mismos organismos. Cada gameta solo posee un alelo de cada gen, ya que son haploides. Entonces los organismos con genotipo Aa, pueden producir gametas A o a. (Ver archivo adjunto)

Como se puede ver en el cuadro, hay un 25% de probabilidades de obtener descendencia con genotipo AA (verde), 25% para aa (rojo) y 50% para Aa (verde). Lo mismo se puede expresar como 2:1:1 (de un total de 4, 2 son Aa, 1 es AA y 1 es aa). Recordando que el alelo A es dominante sobre a, la frecuencia fenotípica será de 75% verde y 25% rojo, lo que se puede expresar como 3:1 (de un total de 4, 3 son verdes y 1 es rojo).

Para concluir, recordemos que los genes codifican para las características visibles (fenotipo), y el conjunto de genes forma el genotipo. Para cada gen, hay dos alelos que ocupan un determinado locus o posición en el cromosoma y los mismos pueden ser dominantes o recesivos. Para estudiar esto, se pueden utilizar cuadros de Punnett en donde se cruzan organismos maternos y paternos, conociendo sus genes para así determinar el posible genotipo y fenotipo de la descendencia que puedan tener. Aunque hay que considerar que puede ocurrir una mutación en sus gametas, que se herede y afecte los genes y las características visibles.

How can the percentage of air be determined

Answers

Answer:

The composition of air can be determined by an experiment which includes passing a known volume of air, measured at a known temperature and pressure, over sufficient amount heated copper granules/powder, and measuring the volume gas remaining after the gas cools down to the temperature at which the first measurement was taken

Oxygen reacts with copper according to the following chemical reaction

2Cu (s) + O₂ (g) → 2CuO (s)

Cupper does not react with the other constituents of air

Whereby the initial volume of air was 100 cm³, we have;

Percentage of oxygen in air = 100 - The final volume reading of the container initially holding the air

When done using am appropriate experimental setup, the percentage of gases remaining equals 79% to 80%, therefore, the percentage composition of oxygen in air is between 20 and 21 percent

When a single salt crystal is added to a cool liquid, large crystals form. Which statement about the original cool liquid is correct?

A) The liquid is a heterogeneous mixture because the crystals can be easily separated from the liquid

B) The liquid is a pure substance because it was made up of a single compound

C) The liquid is a pure substance because it was uniform before the crystal was added

D) The liquid is a homogenous mixture because the substance that formed the large crystals was uniformly dissolved

Answers

The liquid is a homogeneous mixture because the substance that formed the large crystals was uniformly dissolved.

A solution is composed of a solute and a solvent. A solution is a typical example of a homogeneous mixture.

We define a solution as any combination of solute and solvent. A solution can be regarded as a homogeneous mixture since the solute is uniformly distributed throughout the solution. The solute and solvent constitutes one phase.

When a salt crystal is added to the solution, crystallization is induced and large crystals of solute form.

https://brainly.com/question/9970247

A salt crystal is a cubic form of sodium chloride that is closely bounded together by the reaction of sodium and chlorine ions during electrovalent bonding.

Taking a look at a heterogeneous mixture;

It refers to the mixtures that are not thoroughly mixed and uniform in composition.

On the other hand, homogeneous mixtures are formed when a substance i.e. solute (here, it is the salt crystal) is being added to a cool liquid(solvent) is thoroughly mixed.

From the given information, we are being told that when this single salt crystal is added to the cool liquid, large crystals are formed.

This implies that the formation of large crystals is brought about by the action of crystaliization rendering the liquid to be a homogeneous mixture.

We can therefore conclude that the correct statement about the original cool liquid is in Option D.
