Por que las hojas de la lechuga se ponen turgentes al dejarla en agua y luego al preparar la ensalda se arruga
Answer: Las células de la lechuga son hipertónicas al agua fresca (el agua entra en las células y se hinchan) pero hipotónicas a una solución salina (el agua sale de la célula y se arruga)
Explanation:
La lechuga (Lactuca sativa) es una planta de la familia Asteraceae, que se cultiva sobre todo como verdura de hoja para su consumo, aunque también se utilizan las semillas y el tallo. La lechuga se utiliza especialmente para las ensaladas, aunque también se ve en otros tipos de comida, como sopas o sándwiches.
Cuando la hoja de lechuga se deja en agua, dicha agua entra en las células mediante ósmosis, el cual es es un mecanismo de difusión pasiva en donde el agua se transporta a través de una membrana semipermeable yendo desde la región de mayor concentración al de menor concentración. Cuando se coloca una célula vegetal (en este caso de lechuga pero puede ser de cualquier vegetal) en una solución hipotónica, el agua se desplazará hacia las células vegetales y éstas se hincharán. Esto se debe a que una solución hipotónica es una solución que tiene una menor concentración de solutos en comparación con otra solución en el interior de la célula.
En el caso en el que se prepara una ensalada, las hojas de lechuga se arrugan porque al agregar sal, el medio se convierte en hipertónico y a través de ósmosis, el agua saldrá del interior de la célula y por ello, se arrugan. Hipertónico significa que el entorno exterior a la célula tiene una mayor concentración de solutos que la propia célula. Además, las células de la lechuga están cubiertas por una capa impermeable y esto evita que el agua salga de la célula al medio exterior y que la sal entre desde ese medio.
Entonces, las células de la lechuga son hipertónicas al agua fresca pero hipotónicas a una solución salina (agua con sal).

For decades, scientists relied on the fossil record and comparative anatomy to assemble evolutionary lineages. Which statement describes a limitation of these methods? (1 point) They are no longer relevant because the fossil record is complete. They can show false relationships between organisms that are not reflected in the DNA. They are not reliable evidence of how the body structures of organisms evolved. They cannot be used to determine when species evolved.
Answer: They can show false relationships between organisms that are not reflected in the DNA
Explanation:
Okay so there is a thing called "convergent evolution" which basically means that different species coming from different evolutionary lines evolve the same traits. It's really easy to mistake convergent evolution for evolutionary similarities. From the fossil record, it's easy to see the bones of one animal and to see that they are similar to another but that doesn't prove that they are related because it's often due to convergent evolution.
They can offer false relationships between organisms that are not reflected in the DNA. Also, they don't prove they are related due to convergent evolution.
What is DNA?
There is a thing called "convergent evolution" which essentially suggests that additional species coming from different evolutionary strings become the same traits.
It's really easy to misunderstand convergent evolution for evolutionary parallels.
From the fossil record, it's easy to catch the bones of one animal and to see that they are equal to another but that doesn't confirm that they are connected because it's often due to concurrent evolution.

Use a Punnett Square of a Bb x Bb cross. B is the factor for brown eyes and bis factor for blue eyes. What color eyes do the parents have:
Answer:
The parents would have brown eyes.
Explanation:
Given Bb x Bb, this tells you that both parents have brown eyes and are carriers for a reccessive trait (blue eyes). Remember that the uppercase letters are considered dominant and the lower case letters are considered recessive. In order for the blue eye allele to show, you would need to have the genotype: bb.
