Answer:

The idea that chromosomes orient themselves randomly during metaphase I is Independent Assortment. This leads to more combinations of genes.

Explanation:

During metaphase I, the pair of chromosomes align in the plate of the cell. In this step, the independent assortment takes place.

The independent assortment is the distribution of different genes into two gametes, is independent, because the distribution of the different genes, does not influence the distribution of the other genes. The independent assortment leads to new combinations of genes from the parental and maternal side, resulting in offsprings that do not look exactly like their parents.

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).

Naily [24]
In order to solve this problem we use these formula:
<span>p2 + 2pq + q2 = 1p + q = 1p = % dominant allele in the population
q = % recessive allele in the population
p2 = % homozygous dominant individuals
q2 = % homozygous recessive individuals
2pq = % heterozygous individualsFrom the given, we haveq2 = 21%Simply taking the square root,q = 4.58%</span>
