yall what do ya think shaped ya feelings bout science classes?
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.

b Verdadero

mayúscula representa el alelo recesivo y la letra minuscula representa al alelo dominante.

3. Usualmente los cruces se presentan en un cuadro de Punnett, y ayuda a determinar la probat
de un genotipo y fenotipo en particular
a Falso

conociendo la dominancia y el genotipo de un progenitor
Falso

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.

When a leaf of fresh sage or mint is rubbed ,the fragrance is
immediately obvious. Write a theoretical explanation for this observation
Answer: Volatile compounds present in the fresh sage leaf or mint leaf evaporate on rubbing.
Explanation:
When fresh sage or mint is rubbed on the skin or any other surface the volatile chemicals associated with the integral structure of the plant part get evaporated in the surrounding air and the vapors can be detected by the olfactory receptors present in the nose. These receptors take the smell or fragrance stimulus and generate impulses or signals which goes to brain and brain interprets the smell or fragrance.
