The correct answer is D) production of a zygote with a complete set of chromosomes with genetic material from two parents

The nucleus of a cell is <em>haploid</em> if it has a <em>single </em>set of chromosomes, diploid if it has two sets of chromosomes etc.

Gametes are haploid cells in sexually reproducing organism. During fertilization (conception) in organisms that sexually reproduce, two gametes (haploid cells) fuse with one another which results in a production of a zygote with a complete set of chromosomes with genetic material from two parents. In this case, the zygote is going to be diploid.

The right answer is D.

A gamete is a generally haploid reproductive cell specialized in fertilization, or gamy (that is to say, able to fuse with another gamete, complementary type if necessary), in eukaryotes.

The process that carries out the fusion of two gametes is called fertilization or gamy, it is the complementary event of meiosis. Fertilization produces a new single cell, called a zygote, whose chromosome number has doubled to 2n.

Aleonysh [2.5K]

Answer:

La pata de un pato y la aleta de un pez son en ambos casos son elementos que les permiten tanto al pato como al pez moverse, además de sus funciones de estabilidad. La aleta de una ballena y el brazo del ser humano, sucede lo mismo que en el caso anterior. En el caso de la aleta de la ballena, es como la aleta del pez. En cuanto al brazo del ser humano permite realizar movimientos que contribuyen al desarrollo de sus funciones, como por ejemplo, agarrar distintos elementos. La pelvis reducida de los cetáceos no tiene actualmente ninguna función.

Explanation:

La pata de un pato es una extremidad que por su estructura le permita nadar perfectamente. En cuanto a la aleta de los peces y ballenas, es una parte de estos animales formada por tejido conjuntivo. Pueden tener distintos tamaños y su principal función no sólo es permitir el movimiento sino también la estabilidad. En cuanto a la pelvis reducida de los cetáceos era algo que tenía sentido en especies de antaño. Durante la evolución, su utilidad de fue perdiendo, como podría mencionarse el ejemplo en los humanos de las muelas de juicio.
