Letter A Animals are eukaryotes
Answer: Parasitism, Predator-Prey, Competition
Explanation:
The symbiotic relationship is the relationship in which two distinct species are associated with each other. In the symbiotic relation the species may get harm or benefit of association. Parasitism can be defined as the symbiotic relationship in which one species get harmed and other one receives the benefit. For example, malarial parasite plasmodium derives the nourishment from the host body (human). Predator-prey relationship is also harmful as the predator kills the prey to obtain it as food. Competition is harmful in the sense two or more organisms of the same or different species compete for the same resource, the most dominant receives the resource the inferior organism is either killed or harmed in the fight for resources.
Each organelle, in a cell, works with all of the other organelles to maintain balance, or homeostasis. The organelles have specific functions such as the mitochondria, which create energy, and the ribosome, which translates RNA into proteins. Because these cells work together, the body is able to maintain homeostasis.
The two main variables in an experiment are the independent and dependent variable.
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.
A dependent variable is the variable being tested and measured in a scientific experiment.
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.
For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source) would be the dependent variable.
When results are plotted in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis.
