Andre45 [30]

Answer:

La reproducción sexual consisten en la unión de dos gametos uno femenino y otro masculino, para formar un nuevo individuo con características provenientes de ambos progenitores. Los gametos son células especializadas que se forman por un proceso meiótico y tienen en su núcleo la mitad de la información genética de un organismo, por lo que reciben el nombre de células haploides de manera que cuando se une sus cromosomas se forman células diploides característico de la especie. La característica más importante de este tipo de reproducción es la variación genética que implica que los descendientes tengan características de sus dos progenitores, por lo que son diferentes a ellos. El proceso en el que se une las células sexuales se le conoce como fecundación. En los animales esta pude ser interna o externa.

Explanation:

Los gametos (óvulos y espermatozoides) son células germinales especializadas que se desarrollan a partir de un proceso llamado gametogénesis (espermatogénesis en machos y ovogénesis en hembras). El proceso de gametogénesis implica un tipo de división celular llamado 'meiosis' donde la cantidad de cromosomas se reduce a la mitad. En humanos, el número cromosómico diploide (2n) de 46 cromosomas se reduce a un número haploide (n) de 23 cromosomas. La fecundación es el proceso por el cual los gametos se fusionan durante la reproducción sexual para producir un cigoto diploide. En la reproducción sexual, el aumento de la variación genética en la progenie es un resultado de tres procesos diferentes: la unión aleatoria entre gametos durante la fecundación, la distribución independiente de los cromosomas durante la gametogénesis y el entrecruzamiento (recombinación o crossing over) entre cromátidas de cromosomas homólogos durante la meiosis. Finalmente, en animales, la fecundación puede ser interna, la cual se produce mediante la unión de los gametos dentro del cuerpo de la hembra (por ejemplo, gallina, leona, cebra, etc.), o fecundación externa, donde la fusión de gametos se produce en el ambiente externo (por ejemplo en peces, sapos, ranas, etc.).

Describe the relationship between the wavelength and frequency of electromagnetic waves
larisa [96]

Answer:

Frequency is inversely proportional to wavelength.

Explanation:

frequency is the number of oscillations in a unit of time.

Wavelength is the length between one oscillation and the next oscillation.

take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)

Now get two pins and pin them at a certain distance apart.

take the first spring and attach its two terminals to the pins.

Repeat the above procedure, but double (increase the distance x2) the distance between two pins.

Now you have to measure how many coils are there within 5cm of the two springs.

you'll observe that the second spring has half the coils of the first spring within 5cm.

In here no. of coils is the frequency

5cm length is time.

distance between coil is the wavelength.
