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.
Answer:facilitated diffusion
Explanation: facilitated diffusion us the carrier-mediated Transport of large molecules across the cell membrane using Transport proteins found in the cell membrane.such molecules include glucose,amino acids and ions.the passage across the membrane is from higher concentration to lower concentration
Identify the process by which natural selection acts on Change in Population the surviving insects reproduce. The frequency of resistant insects in the population increases.
- Pesticides are any poisonous substances that are employed to kill animals, fungi, or plants and cause financial loss to crops or ornamental plants or pose a risk to domestic animals' or humans' health.
- A pesticide is used on an insect population. Some insects possess a trait that renders them pesticide resistant. These flies remain. Without the gene, insects perish.
- Insects that are still alive reproduce. Insects that are resistant are becoming more prevalent. Ecological Change Insecticide is used on a population of them.
- Choosing Pressure Some insects have a trait that renders them pesticide resistant. These bugs are persistent. Without the gene, insects perish.

Answer:
a mutation that blocks the GTPase activity of Ras
Explanation:
A G protein in inactive state is GDP bound but as soon as a guanine exchange factor (GEF) exchanges it with GTP it gets activated which means that in GTP bound state it is active. G - protein has endogenous GTPase activity. Upon interaction of GAP, the GTPase activity of this protein is exhibited. When GAP is present, hydrolysis of GTP into GDP occurs which leads to inactivation of G protein. A mutation which will block GTPase activity of Ras will therefore result in constitutive active signaling even in the absence of ligand binding to it's receptor. In such scenario, GTP will not be hydrolyzed into GDP so signaling will be up-regulated.
The answer that you would like to put is:
The force between charges decreases as the distance between them increases. Like charges repel each other. Oppostite charges attract each other
