To hypothesize: the successful evolutionary advantages of animal sacrificing themselves for their sibling in a competitive battle with a predator.
Introduction:
Behaviors that have an objective to cause harm or pain is known as aggression. This type of behavior occurs when individuals compete for the same

Explanation of Solution
Animal sacrificing themselves for their siblings in a competitive battle with a predator have an evolutionary advantages. Animal may die in a competitive battle but by protecting it sibling they increases the chance of transmitting their gene pool to the next generation. Due to this chance of extinction of animal species decreases.
Animal sacrificing themselves for their siblings in a competitive battle with a predator increases the chance of survival of species and helps in transmitting gene pool to the next generation.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes. Which of the following Plasmodium species is most likely responsible for her severe symptoms? A. Plasmodium vivax B. Plasmodium ovale C. Plasmodium malariae D.
