The service box is an area on the court that 1 point the person serving must stand in. the ball must land in to be a playable serve. the person returning the serve must be standing in before a server can serve
Answers
Answer:
Both players on the serving doubles team have the opportunity to serve and score points until they commit a fault *(except for the first service sequence of each new game).
The first serve of each side-out is made from the right-hand court.
If a point is scored, the server switches sides and the server initiates the next serve from the left-hand court.
As subsequent points are scored, the server continues switching back and forth until a fault is committed and the first server loses the serve.
When the first server loses the serve the partner then serves from their correct side of the court (except for the first service sequence of the game*).
The second server continues serving until his team commits a fault and loses the serve to the opposing team.
Once the service goes to the opposition (at side out), the first serve is from the right-hand court and both players on that team have the opportunity to serve and score points until their team commits two faults.
In singles the server serves from the right-hand court when his or her score is even and from the left when the score is odd.

In North America, the eastern spotted skunk mates
in late winter, and the western spotted skunk mates
in late summer. Even though their geographic
ranges overlap, the species do not mate with each
other. What most likely prevents these two species
from interbreeding?
A. habitat isolation
B. gametic isolation
C. geographic isolation
D. reproductive isolation
Answers
Reproductive isolation is a mechanism through which species do not get to interbreed. Option D. reproductive isolation
What is reproductive isolation?This is a mechanism through which different species or populations do get to mate and produce fertile offspring. This mechanism allows the accumulation of genetic differences and favors speciation.
There are different barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers prevent mating between two or more species. There are two types of barriers,
prezygotic ⇒ that avoids fertilization between individuals of different species, postzygotic ⇒ that impedes the zygote to develope and reach the adult stage.Pre-copulatory o pre-ziygotic:
• Ecological or by habitat isolation;
• Seasonal or temporal;
• Séxual o ethologic;
• Mechanic;
• Gametes incompatibility.
Postzygotic mechanisms or barriers include
• Hybrid inviability,
• Hybrid sterility,
• Cytoplasmic interactions.
In the exposed example occurs a seasonal difference between the mating period of the eastern spotted skunk and the western spotted skunk.
Probably, if both of them would mate during the same season and in the same area, they could reproduce.
However, since their mating season differs, individuals from each species do not get to cross and hence, produce fertile offspring.
Option D. reproductive isolation is what most likely prevents these two species from interbreeding

Answers
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.).

Answers
Both prokaryotic and eukaryotic cells use RNA polymerase to turn certain genes on or off. The correct option is A.
What is RNA polymerase?RNA polymerase, or more specifically DNA-directed/dependent RNA polymerase, is a molecular biology enzyme that synthesizes RNA from a DNA template.
The RNA polymerase enzyme is a large complex composed of many subunits. The prokaryotic RNA polymerase has four subunits that can transcribing all types of RNA.
These enzymes in eukaryotes have eight or more subunits that aid in the attachment and processing of DNA during transcription.
RNA polymerase (abbreviated RNAP or RNApol), or more specifically DNA-directed/dependent RNA polymerase (DdRP), is a molecular biology enzyme that synthesizes RNA from a DNA template.
RNA polymerase is used by both prokaryotic and eukaryotic cells to turn genes on and off.
