Are starch molecules or glucose molecules bigger?
Answer: Starch
Explanation:
Why is starch larger than glucose? Based on the experiment, starch molecules are bigger in comparison to glucose molecules because they could not leave the tubing. This is supported by the presence of color change in the tubing for the starch test.
Starch molecules are polysaccharides and big sugar molecules, whereas glucose is a monomeric carbohydrate. Thus, starch molecules are bigger than glucose molecules.
What are starch molecules?Starch is an insoluble carbohydrate that is tasteless and soft sugar with molecular formula, (C₆H₁₀O₅)ₙ. They are categorized as polysaccharides as they are made of more than two sugars linked through glycosidic bonds.
The starch is a complex sugar molecule made of many glucose monomeric units linked by α 1,4 linkages. It is present in food sources and is consumed for energy. On the other hand, glucose is a simple carbohydrate that is categorized as a monosaccharide due to single sugar.
As starch is a polysaccharide and has n number of carbons they have a large molecular weight and structures as compared to the glucose molecule with less molecular weight.
Therefore, starch is a bigger molecule.

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.

Al wonders if adding salt to water will affect how long it takes the water to
freeze. Al thinks that salt water will freeze more quickly than fresh water.
He decides to check his hypothesis by conducting an experiment. Al takes
two ice trays and fills one with distilled water and the other with distilled
water that has two tablespoons of salt added. He makes sure he puts
exactly the same amount of water in each ice tray. Al takes the trays and
puts them side by side in the freezer. Al checks the ice trays every 10
minutes to see if the water in each tray has begun to freeze. Al finds that
after 20 minutes the water in the ice tray without the salt has started to
form ice, while the ice tray with the salt water is still completely liquid.
Ku
The hypothesis is that salt water freezes faster than fresh water.
The dependent variable is time taken for ice to appear.
The independent variable is presence or absence of salt
The constants are the amount of water in each tray, freezing conditions and length of time of exposure to freezing condition.
The control group is the tray to which salt was not added
The experimental group is the tray to which salt was added
The presence of solutes in a solution causes the freezing point depression.
A solution is made up of a solute and a solvent. In the presence of a solute, the freezing point of a pure solvent is decreased. This is because freezing point is a colligative property.
Colligative properties depend on the amount of solute present.
Hence, the pure water freezes faster (ice begin to appear earlier) than the salt water.
The hypothesis put forward in this experiment was found to be invalid by the experiment.

Using d = m/V, what is the (V)olume of a solid that has a density is 14g/cm² and has a
mass of 7 grams.
Answer:
0.5cm²
Explanation:
the volume is found by dividing the mass over the density
v=m/d
=7g/14g/cm²
=0.5cm²
i hope this helps
Answer:
[tex]\boxed {\boxed {\sf 0.5 \ or \ \frac {1}{2} \ cm^3}}[/tex]
Explanation:
We are asked to find the volume of a solid given the density and mass. The formula for density is:
[tex]d= \frac {m}{v}[/tex]
We know the solid's density is 14 grams per cubic centimeter and the mass is 7 grams.
d= 14 g/cm³m= 7 gSubstitute the known values into the formula.
[tex]14 g/cm^3 = \frac{7 \ g}{v}[/tex]
We are solving for the volume of the solid, so we must isolate the variable v. First, cross multiply. Multiply the first numerator by the second denominator, then the first denominator and second numerator.
[tex]\frac {14 g/cm^3}{1} = \frac{7 \ g}{v}[/tex]
[tex]14 \ g/cm^3 * v= 7 \ g * 1[/tex]
[tex]14 \ g/cm^3 * v= 7 \ g[/tex]
Now the variable is being multiplied by 14 grams per cubic centimeters. The inverse operation of multiplication is division, so we divide both sides by 14 g/cm³.
[tex]\frac {14 \ g/cm^3 * v}{14 \ g/cm^3}= \frac {7 \ g }{14 \ g/cm^3}[/tex]
[tex]v= \frac {7 \ g }{14 \ g/cm^3}[/tex]
The units of grams cancel.
[tex]v= \frac {7 }{14 \ cm^3}[/tex]
[tex]v= \frac {1}{2} \ cm^3[/tex]
The volume of the solid is 1/2 or 0.5 cubic centimeters.
