Answer:When two true breeding plants breed they produce an F1 generation. The genotype for the true breeding parents would be TT and tt. Each of the offspring in the F1 generation would have the genotype of Tt and would have the phenotype of being tall, since tall is dominant. Next, we breed the plants of the F1 generation to produce the F2 generation. We know that the phenotype of the parents are both Tt. From this you can create a punnet square:
T t
T TT Tt
t Tt tt
Explanation:TT is expressed as tall
Tt is expressed as tall
tt is expressed as short
The punnet square shows you that 75% would be tall and 25% would be short.
The 200 short plants in the questions would be 25% of 800. Take the 200 away from 800 and you get approximately 600 that would be tall.
Answer:
una alimentación saludable y la práctica de ejercicios físicos contribuyen al normal funcionamiento de la tiroides y mejoran el estado de ánimo
Explanation:
La tiroides es una glándula cuya función es secretar hormonas tiroideas tales como tiroxina y triyodetironina, las cuales están implicadas en el crecimiento y el control del metabolismo. Es bien conocido que problemas de salud tales como hipotiroidismo (hormonas tiroideas a concentraciones muy bajas) o hipertiroidismo (hormonas tiroideas a concentraciones excesivamente altas) afectan el estado de ánimo, y llevan a cuadros de estrés emocional como ansiedad y depresión. Una alimentación balanceada basada en alimentos ricos en yodo (pescados del mar, huevos, camarones) y zinc (maní, carne, semillas de calabaza, almendras), como así también el ejercicio físico regular, pueden producir el restablecimiento de los niveles normales de tiroxina y triyodotironina en personas con hipotiroidismo, lo cual ha sido asociado con una mejora inmediata en el estado de ánimo.

Answer.
ADH is released from the hypothalamus in response to high tissue osmolarity. In response to ADH, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into the capillaries.
Explanation
. This option is the mechanisms of regulation of osmoregulatory balance in urine production by the kidney
ADH responds to high solute potential of the blood(high osmolarity) by stimulating the opening of transmembrane proteins AQUAPORINS in the walls of the distal and collecting tubules
This promotes influx of Solutes from the passing tubules into the peritubular capillaries.Water follows by osmosis(reabsorption),untill the osmolarity of these fluids drops.
As this occurs the hypothalamus stopped the production of ADH, the aquaporins closes up,solute influx into peritubular capillaries stoped and therefore water influx
This is negative feedback Mechanism.it is an example of homeostatic process of maintaining water balance of the body during urine formation .
