There are some possible answers which all mean the same thing:
- Produce fertile offspring
- Produce offspring
- Reproduce
→ Only individuals of a same species (sometimes genus) can reproduce because in order to reproduce animals need to have a similar genetic code, and there is now code more similar than the one of individuals of their own species.

Answer:
Influenza is caused by a lytic virus while Hepatitis C is caused by a non-lytic virus.
Explanation:
The lytic cycle for reproduction enables the virus to make several copies of itself and destroys the host cell in the process. Many bacteriophages (viruses that infect bacteria) adhere to the lytic cycle. During the lytic cycle, once the virus has attached itself to the host cell, it injects its DNA into it. The virus is thus able to use the host cell's machinery to synthesize proteins and replicate itself.

Bilirubin is a byproduct of red blood cell destruction and are conjugated in the liver and excreted in bile.
Population of older female elephants different from the younger female elephants is described below.
Explanation:
- THE OLDEST ELEPHANTS wandering Mozambique’s Gorongosa National Park bear the indelible markings of the civil war that gripped the country for 15 years: Many are tuskless. They’re the lone survivors of a conflict that killed about 90 percent of these beleaguered animals, slaughtered for ivory to finance weapons and for meat to feed the fighters.
-
Hunting gave elephants that didn’t grow tusks a biological advantage in Gorongosa. Recent figures suggest that about a third of younger females—the generation born after the war ended in 1992—never developed tusks. Normally, tusklessness would occur only in about 2 to 4 percent of female African elephants.
- New, as yet unpublished, research she’s compiled indicates that of the 200 known adult females, 51 percent of those that survived the war—animals 25 years or older—are tuskless. And 32 percent of the female elephants born since the war are tuskless.
- A male elephant’s tusks are bigger and heavier than those of a female of the same age, says Poole, who serves as scientific director of a nonprofit called ElephantVoices. “But once there’s been heavy poaching pressure on a population, then the poachers start to focus on the older females as well,” she explains. “Over time, with the older age population, you start to get this really higher proportion of tuskless females.”
- “The prevalence of tusklessness in Addo is truly remarkable and underscores the fact that high levels of poaching pressure can do more than just remove individuals from a population,” says Ryan Long, a behavioral ecologist at the University of Idaho and a National Geographic Explorer. The “consequences of such dramatic changes in elephant populations are only just beginning to be explored.”
Answer:
En el hemisferio sur el verano comienza en diciembre y finaliza en marzo, mientras que el invierno comienza en junio y finaliza en septiembre.
Perú se encuentra en el hemisferio sur, con lo cual el verano comienza el 21 de diciembre y finaliza el 21 de marzo, mientras que el invierno comienza el 21 de junio y termina el 21 de septiembre.
El afelio indica a la mayor distancia posible en la órbita de un planeta con respecto al Sol, mientras que el perihelio refiere a la menor distancia posible (es decir, el punto de mayor cercanía posible) entre la órbita de un planeta y el Sol. En la Tierra, el afelio se produce a comienzos de julio, donde nuestro planeta dista aproximadamente 152 millones de kilómetros con respecto del Sol, mientras que perihelio se produce a principios de enero, donde la Tierra dista aproximadamente 147 millones de kilómetros con respecto del Sol.
La caída de lluvia es un fenómeno independiente a la estación del año, es decir, la lluvia caída en enero o julio no modifica que en el hemisferio sur nos encontremos en verano e invierno, respectivamente. En algunas regiones las lluvias se concentran en un determinado período del año, lo cual es un fenómeno meteorológico que tampoco tiene incidencia sobre la estación del año.
