I'm pretty sure that this is the correct answer "The enzymes in the second test tube must have denatured at 1000C, since most enzymes degrade at such high temperatures." that is if you're using Plato, in which case this would be one of your answer choices.
The correct option is (a) 2 → 4 → 1 → 3
A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.
<h3>
What is genetic variation in population?</h3>
- The presence of various alleles, or different gene versions, within a population indicates genetic variety.
- If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
- Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.

Answer:
50%
Explanation:
La información que tenemos es:
Un hombre homocigoto (ee) que carece la posibilidad de enrollar su lengua.
Una mujer heterocigota (Ee). Al tener dos copias distintas de este gen, la mujer puede enrollar su lengua ya que este es un gen dominante (E) sobre el gen recesivo (e) que impide este movimiento.
Si hacemos un Cuadro de Punnett veremos que la capacidad de enrollar la lengua en los descendientes de esta pareja tiene una probabilidad fenotípica del 50% ya que hay un 50% de probabilidades de que su descendencia tenga un genotipo Ee y otro 50% de que sea ee, lo cual se expresa en una probabilidad fenotípica, es decir lo que se puede apreciar visiblemente como resultado de la interacción del genotipo y el ambiente, de con un 50% de poder enrollar la lengua.

Answer:
d. Epithelial tissues are nourished by blood vessels in adjacent tissues, thus diffusion is limited to thin tissues.
Explanation:
Epithelial tissues have tightly packed cells and have no space for blood vessels to be present between adjacent epithelial cells. The cells of the epithelial tissues get nutrients from the blood vessels of neighboring connective tissues.
Since the exchange of nutrients between the cells of the epithelial and connective tissues occurs through diffusion, epithelial tissues are only one to few cells layers thick to allow nutrient supply to all of its cells.
