The ovary is the expanded inferior part of the carpel. It contains the ovules waiting to be fertilized by pollen.
<span>The function of an ovary is to hold egg cells in a flower to use when beginning the reproductive cycle.</span>
Energy doesn't mean it's necessarily available to do work. energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. (etc.)
Although not specified, I am assuming that you want to identify the different variables and groups of this case. To answer this, the different typical factors that make up an experimental set up include: 1) dependent and 2) independent variables; 3) controlled variables; as well as the 4) control and 5) experimental group.
The dependent variable in this case is: the size of the population. While the independent variable is: the habitat space. Controlled variables in this experiment include: type and amount of food, cleanliness of the aquarium, and water temperature. The experimental group are simply the fish being observed. There are no controlled groups in this case depending on your definition. Controlled groups are usually the reference point or standard in experimental setups but this experiment wants to look at the differences of the goldfish with each other and not necessarily to a one particular goldfish and hence no controlled group.
The dependent variable is called as such because it is the one that changes depending on the factors given and is usually the one being observed. The independent variable is named as such because it remains the same throughout the experiment.
The best choice is Vascular and Dermal
