Conversion of spermatids to spermatozoa involves cell division.<br> a. True<br> b. False
FrozenT [24]

Answer:

The correct answer will be option-False.

Explanation:

Spermatogenesis or formation of sperm cells in humans takes place in two stages: cellular division called "spermatocytogenesis" and metamorphic changes in spermatids to spermatozoa called "Spermiogenesis".

The mitotic and meiotic cellular division produces round spermatids which undergo much physical change during the process called Spermiogenesis.  During Spermiogenesis spermatids modify themselves for fertilization like acrosome cap formation, tail development and nuclear condensation.

Thus, option-false is the correct answer.

This is still a reliable source because it clearly cites scientific research. Sometimes sources flatly contradict a given statement, study or an existing fact.

Redacta un escrito dónde expliques como está formado(un ecosistema), menciona ejemplos y como sigue una estabilidad por el equil
IceJOKER [234]

Answer:

Un ecosistema esta formado por facotres abioticos y bioticos.

Los factores bioticos son aquellos que presentan signos vitales, es decir que cumplen con la vida, metabolismo, respiracion, entre otras funciones vivas.

Los factores abietos son aquellos que no tienen vida pero con los que los factores bioticos intercambian energia, un ejemplo de esto son las rocas, los vientos, los sedimentos, la tierra fertil.

Los factores bioticos serian los organismos vivos como los animales, que al funcionar como sistemas abiertos de intercambio de energia constante mantienen un equilibrio fisico biologico con los factores bioticos.

Explanation:

Los ecosistemas cumplen con una cadena que no debe romperse ni faltar ningun eslabon, si esta continuidad se interrumpe con la extincion de una especie como animal o vegetal el ecosistema variará, y cambiara toda su conformacion.

Es un conjunto de factores bioticos y abioticos en armonia que se complementan e intercambian energia entre si de manera ordenada en eslabones, si uno de estos eslabones se rompe, se extingue, o se modifica por intervencion del hombre u otros factores TODO el escosistema se verá modificado o afectado.
