Given a population that contains genetic variation, what is the correct sequence of the following events under the influence of
GuDViN [60]

Answer:

2. A change occurs in the environment.

4. Poorly adapted individuals have decreased survivorship.

1. Well-adapted individuals leave more offspring than do poorly adapted individuals.

3. Genetic frequencies within the population change.

Explanation:

The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.

Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.

Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.

Hence, the sequence of events is 2, 4, 1 and 3.

IrinaVladis [17]

Answer:

a) Las raíces superficiales y extensas

c) El cuerpo carnoso de las plantas

d) Las hojas modificadas en forma de espina

Explanation:

En biología, una adaptación refiere al proceso de cambio evolutivo mediante el cual los organismos de una especie/taxón hacen frente a determinadas condiciones ambientales. Las plantas han desarrollado diferentes adaptaciones en ambientes desérticos a fin de evitar al máximo la pérdida de agua, el factor más limitante en este tipo de ambientes. Las plantas capaces de soportar largos periodos de sequías se denominan xerófitas. En primer lugar, además de servir como una buena defensa contra herbívoros, las hojas en forma de espina le permiten a una planta almacenar agua durante los períodos de precipitaciones. En segundo lugar, las raíces de plantas desérticas pueden disponerse superficialmente con el objetivo de absorber la mayor cantidad de agua posible. En tercer lugar, las plantas suculentas o crasas son aquellas que tienen tejidos carnosos los cuales pueden almacenar agua en sus hojas, tallos o raíces. Durante los periodos de lluvia leve, las suculentas almacenan grandes cantidades de agua para sobrevivir durante la temporada seca (incluso existen especies vegetales que sobreviven solamente durante la temporada húmeda y producen semillas que toleran la temporada seca).
