A thoracic aortic aneurysm refers to a weakened section located in the upper part of the aorta, the primary artery responsible for supplying blood to the entire body.
When the temperature decreases, it indicates negative feedback, whereas an increase signifies positive feedback.
Answer: Amylase
Explanation: it’s an enzyme found in saliva that facilitates the breakdown of starches, such as those present in pasta, aiding in food digestion.
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)
