Explanation:

A limited factor that causes adaptation is the loss of habitat,food,or new species.

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.).

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.

Explanation:

Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant  produced. This is common in premature infants.

Explanation:

Respiratory distress syndrome (RDS) is a well-known breathing disorder that is common in premature infants. It happens when there is a lack of surfactant produced in the baby's lungs which is quite bad because surfactant enables babies to breathe when they are born by keeping the lungs expanded.

It is common in premature infants because the lungs only begin to produce surfactant in the third trimester so babies that are born prematurely did not get to produce sufficient quantities. If not treated immediately, brain damage could follow.

Answer:

b

Explanation:

Natural selection will  only lead to evolution if it allows for an organism to process traits, compete for resources and produce offspring. The correct option is d.

Natural selection is indeed an evolutionary mechanism. Lifeforms which are better adapted to their surroundings are much more likely to flourish and pass on the genetic traits that helped them thrive. Species change and diverge as a result of this process.

Natural selection, Darwin proposed, is a framework for evolution in which genetic variants that help support life, reproduce and survive as well as become more prevalent in a population over time.

Natural selection will occur if three conditions are met, according to Darwin's theory. These conditions, which are outlined as,

These are the conditions that are said to be both necessary and sufficient for natural selection.

Natural selection will only result in evolution if an organism is able to process traits, compete for resources, and produce offspring.

Thus, the correct option is d.
