Ugo [173]

Answer:

C

Explanation:

A) By far the most groundwater is used for livestock.

B) By far the most groundwater is used by farming households.

C) By far the most groundwater is used for irrigating crops.

D) By far the most groundwater is used for public supply in farming communities.​

Out of these options, I believe that the answer is C because Farmers required a lot of water for irrigation, though it depends on the time period whether it's modern day or 1700s, etc. in order to officially tell.

Hope this helps Merry Christmas

Levart [38]

Answer:

Célula procariota y procariotas.

Explicación:

La célula procariota es un tipo de célula que apareció por primera vez en la Tierra hace unos mil millones de años. Estos tipos de células están presentes en los procariotas, lo que significa que estos organismos no tienen un núcleo verdadero o una membrana nuclear alrededor del núcleo y otros orgánulos de la célula. El ADN del organismo procariótico se encuentra en una parte central de la célula que se conoce como nucleoide. La pared celular de un procariota actúa como una capa adicional de protección, ayuda a mantener la forma y estructura celular y previene la deshidratación.
