Answer:
La diversidad de un ecosistema depende de dos factores, el número de especies presente y el equilibrio demográfico entre ellas. ... Por otra parte, entre dos ecosistemas que tienen el mismo número de especies, consideraremos más diverso al que presenta menos diferencias en el número de individuos de unas y otras especies.

Answer:
a. to treat a disease characterized by a gene that is not expressed.
Explanation:
The RNA interference (RNAi) technique is widely used in molecular biology to inhibit target gene expression at the post-transcriptional level. The RNAi technology uses small interfering RNAs (siRNAs) consisting of 18-22 nucleotides that bind to complementary acid nucleics (i.e., DNA and RNA), thereby inhibiting target gene expression. Recently, it has interestingly been discovered that small RNA sequences targeting promoter regions can also be used to activate the expression of endogenous target genes through a mechanism called RNA activation (RNAa).
Answer:
A quantitative trait is a measurable phenotype that depends on the cumulative actions of many genes and the environment.
Explanation:
These traits can vary among individuals, over a range, to produce a continuous distribution of phenotypes. Examples include height, weight and blood pressure.
Answer:
Transporte activo, El Transporte pasivo es una gran estrategia para el movimiento de que la célula debe hacer es quedarse allí y dejar que las Moléculas se difundan a su interior. Por ejemplo, supongamos que tenemos una alta concentración de iones y sodio en el espacio extracelular(gracias al gran esfuerzo de la bomba sodio-potasio).
The use of synthetic fertilizer instead of organic fertilizer has the advantage of producing more crops in a shorter period of time. The organic fertilizer is slow.
<h3>What is fertilizer?</h3>
Fertilizers are used for crops to feed the large and growing population of the world. It allows for more output in less time. As a result, the soil becomes sterile if it is spread with fertiliser for a long period of time. The soil can't hold the nutrients and minerals because of it. While organic fertilizer takes more time to produce but is good for soil health, the earthworm and other animals can live if the chemical fertilizers are less used and make the soil more fertile.
Hence, the only advantage of using synthetic chemical fertilizer is that it can increase production in less time for some years, but after that, the soil will become sterile.
