Answer: C

Explanation:

Hi, the answer to this problem is C.

This is because it is asking for the complementary strand.

Basically, the nucleotide A goes with T, and C goes with G, and both vise versa.

Since this is DNA, A goes with T.

So you would match it up. For the first one, we have C. That means for the first letter of the correct answer, it should be G. Do this until you get through the whole sequence, and eventually, you will get the answer C.

Hope this helps!

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).
