Explanation:
In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.
The answer is: " 32,768 " .

Explanation:
__________________________________________________________
→ 2ⁿ = ? ; {that is: "2" , raised to the "n th" power, equals {<u>what value</u>} ?
___________________________________________
→ Note that "n" is the haploid number, which is:
"15" (value given within this very question).
__________________________________________________
→ So we plug in "15" for "n" ; to obtain the "final value" —
which is the answer.
__________________________________________________
→ As such: " 2¹⁵ = 32,768 " . (using scientific calculator online).
___________________________________________________
→ The answer is: " 32,768 " .

Answer:
NADPH is formed on the stromal side of the thylakoid membrane, so it is released into the stroma. In a process called non-cyclic photophosphorylation (the "standard" form of the light-dependent reactions), electrons are removed from the water and passed through PSII and PSI before ending up in NADPH.
Answer:
La respuesta correcta es opción C. "Contar con organelos membranosos como los cloroplastos".
Explanation:
Una de las características que diferencia a las células procariontes de las eucariontes, es que las células eucariontes tienen organelos membranosos como los cloroplastos. Las células eucariontes son más complejas que las celulas procariontes, y tienen organelos rodeados por membranas donde efectúan sus distintas funciones celulares. Las células procariontes no tienen organelos y realizan la mayoría de sus funciones directamente en el citoplasma.
