Answer:
It is essential for living organisms to maintain a non-equilibrium state in the concentrations of oxygen and carbon dioxide to facilitate gas exchange. If equilibrium is reached, both respiration and photosynthesis would cease.
Explanation:
- Gases flow from areas of higher concentration to lower concentration along their gradients.
- If organisms achieve equilibrium in carbon dioxide and oxygen levels, gas exchange into and out of cells would stop.
- Equilibrium signifies that gas concentrations equalize on both sides, halting any movement.
- Should gas exchange come to a standstill, respiration and photosynthesis in plants, as well as respiration in animals, would completely halt.
Response:
Este es un ejemplo de dominancia incompleta. Se trata de un fenómeno genético que se manifiesta cuando un gen dominante no logra expresar su totalidad en el alelo recesivo en un alelo heterocigoto dominante.
Por ende, ambos rasgos se muestran, dando lugar a una fusión de los dos alelos para los colores (blanco y rojo). El alelo rojo dominante muestra dominio parcial sobre el alelo blanco recesivo, produciendo así el alelo completamente rosado.
Según la ley mendeliana, las dos flores rojas son heterocigóticas. Por lo tanto, las flores rojas dominantes heterocigóticas deben ser R. El alelo blanco es recesivo (rr) y es enmascarado por el R rojo,
Sin embargo, al cruzar los dos alelos heterocigotos rojos:
Los fenotipos derivan en forma de
RR, (1) rojo Rr Rr (2) rosa rr (1) Blanco.
Esto ocurre porque el alelo rojo dominante no era total / completamente dominante sobre el alelo recesivo blanco en ninguno de los casos, resultando en un alelo rosa (el tercer fenotipo)
Biomes located in temperate zones have undergone the most significant alterations due to human actions. Biomes can be described as communities or assemblages of organisms that are grouped based on shared environmental characteristics. There are five major categories of biomes: aquatic, desert, forest, grassland, and tundra.
Mary initially saw a doctor who wasn't trained in drawing blood or taking x-rays. She subsequently visited a different place that specializes in those procedures.
<span>The result hinges on the type of non-random mating involved. In the case of positive assortative mating, it typically raises the frequencies of homozygous genotypes, as it occurs when individuals pair with similar individuals. Conversely, if the non-random mating is negative assortative, the outcome mirrors that of positive assortative mating, resulting in a decrease in the frequencies of homozygous genotypes.</span>
