All organisms on earth share certain characteristics, but an actual definition of life is not simple. Why?

Biology
1 answer:
algol133 years ago
8 0

Answer:

An <em>organism </em>is any individual living thing but the definition of life is not simple because humans determine what meets the criteria of living and nonliving. However, this does not mean that humans are perfect when it comes to categorization. Viruses fall into a middle area between being classified as living or nonliving since viruses have some, but not all, of the characteristics required to be classified as living.

Según la clasificación de ecosistemas, indica si los siguientes ejemplos de ecosistemas son correctos: Una piscina es un ecosist
Hatshy [7]

Answer and Explanation:

  • <em>Una piscina es un ecosistema acuático y seminatural: FALSO. </em>La piscina corresponde a un ecosistema acuático, siempre y cuando existan seres vivos habitando en ese medio e interactuando entre ellos y con los factores físicos como temperatura del agua, pH, etc. No corresponde a un medio seminatural porque su origen es totalmente artificial, es decir, hecho por el hombre.
  • <em>La pradera es un ecosistema terrestre y natural : VERDADERO. </em>Es terrestre por encontrarse en un espacio continental no inundable, y natural por no ser intervenido por el hombre.
  • <em>Un bosque nativo es un ecosistema terrestre y natural: VERDADERO. </em>Un bosque no es inundable, por lo que se considera netamente terrestre y mientras no sea intervenido por la acción humana es un ecosistema natural.<em> </em>
  • <em>Un arroyo es un ecosistema dulceacuícola y natural: VERDADERO. </em>Entre las posibles ubicaciones de un ecosistema acuático, se hayan aquellos que se encuentran en un medio de agua dulce, tales como arroyos, lagos, ríos, entre otros. Al no ser alterado por el hombre, se lo considera también un ecosistema de origen natural.    <em> </em>
  • <em>El mar es un ecosistema marino y artificial: FALSO. </em>El mar sí es un ecosistema acuático marino. Sin embargo no es un ecosistema alterado o creado por el hombre en forma artificial, sino que tiene un origen plenamente natural.
  • <em>Las ciudades son ecosistemas terrestres y seminatural: FALSO. </em>Pueden ser consideradas terrestres por estar ubicadas en el continente, pero son de origen artificial por ser creadas por el hombre.
  • <em>Las represas son ecositemas seminatural y acuático: VERDADERO. </em>Las represas son creadas en un medio natural que ha sido parcialmente modificado por el hombre, lo que las convierte en seminaturales. Corresponden a ecosistemas acuáticos de agua dulce.

Please help, This is a science sheet for get my grade up.
finlep [7]

Answer:

Well The answer you choose was wrong I think because every living being that has cells need a Nulceus in their cells or the cells won’t work. Fungi have cells and Protista also have a nucleus since it has a cell or cells.

The answer here I would think would be (c) ”many could be found in fresh water”. Fungi don’t usually appear near seas or fresh sources which in this case is a pond and protistia do.
