Answer:

F2:

-75% plantas con flores púrpuras

- 25% plantas con flores blancas

Explanation:

La F1 de un cruzamiento entre líneas puras para un rasgo dominante monogénico (en este caso, color de la flor) es siempre igual al fenotipo para el carácter dominante (en este caso, plantas con flores púrpuras). En este ejemplo, el alelo dominante que codifica para el color púrpura enmascara la expresión del alelo recesivo (flores blancas) en plantas F1 heterocigotas. Por otra parte, el cruzamiento entre plantas F1 con genotipo heterocigoto producirá una F2 con una proporción fenotípica 3:1 (es decir, 3 plantas con fenotipo dominante por cada planta con fenotipo recesivo), lo cual es igual a un 75% de plantas con fenotipo dominante (tres plantas: una con genotipo homocigota dominante y 2 con genotipo heterocigoto) y un 25% de plantas con fenotipo recesivo (una planta con genotipo homocigota recesivo). Esto sucede porque los alelos dominante y recesivo responsables del color de la flor segregan independientemente durante la formación de los gametos en plantas F1 heterocigotas.

The nursing instructor informs the students that which anatomical structure controls the elimination of urine from the body?
Tomtit [17]

The Urinary bladder controls the elimination of urine from the body.

  • The lower abdomen contains this triangle-shaped, hollow organ. Ligaments that are connected to the pelvic bones and other organs hold it in place.
  • When storing pee, the bladder's walls relax and expand; when emptying urine through the urethra, they contract and flatten.
  • The typical healthy adult bladder has a two to five-hour storage capacity of up to two cups of urine.

Three parts of bladder allow urine to be discharged:

  • A pair of sphincter muscles. By tightly shutting around the bladder opening like a rubber band, these circular muscles assist prevent urine leakage.
  • In the bladder's nerves. When it's time to urinate or empty the bladder, the nerves let the person know.
  • Urethra. Urine can travel through this tube and leave the body. Urine leaks from the bladder as a result of the brain's tightening signal to the bladder muscles.

11. Why<br> are<br> organisms with more similar amino acid sequences more closely related?
jok3333 [9.3K]

Answer and Explanation:

Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
