Select the correct answer. An object is acted upon by a force of 22 newtons to the right and a force of 13 newtons to the left.
lana [24]

Answer:The net force is the sum of all the forces acted upon an object. The direction of force depends on which side you are taking as a positive and negative force. If the force of 22 newtons is positive and the force of 13 newtons is negative, they are actng on the object on different directions, thus in order to get the net force, we just sum them up.

newtons

The net force is +9 Newtons.

The phenomenon of single or double fertilization is unique to the seed plants
Ksju [112]

Answer:

Double fertilization

Explanation:

The phenomenon of double fertilization is unique to flowering plants (i.e., angiosperms). Each pollen grain produces two male gametes (sperm cells), one of which fertilizes the egg to form the zygote, whereas the other sperm fuses with polar nuclei in the female gametophyte in order to form a triploid cell (3n) called endosperm. Subsequently, this endosperm will support embryonic growth by supplying storage nutrients and by serving as a mechanical barrier during seed development and germination.

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.
