3. The sperm is produced inside the scrotum and stored in the e<span>pididymis. During ejaculation, the sperm flows through the Vas deferens and the ejaculatory duct before reaching the urethra. The urethra is the tube inside the penis that ends in the preputial orifice or the hole at the tip of the penis where the sperm flows out.</span>

Answer:
Independent Variable - Soil, Dependent Variable - Height, Control Variable - Sun and Water
Explanation:
First we should define what the variables in the experiment are.
Independent variable is the aspect of the experiment that has a different value for each subject in order to find out how it affects the dependent variables.
Dependent variable is the variable that is kept under observation and recorded by the experimenters in order to track the changes and define its relationship with the other variables/parameters.
Control variable is the variable that is kept constant intentionally by the experimenters to be able to define the relationship between the other variables more clearly and easily.
In the example given in the question, there are one of each variable mentioned above which are, according to the definitions;
- Independent Variable - The Soil
- Dependent Variable - The Height Of The Plant
- Control Variable - The Amount of Water and Sun Exposure

Answer:
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.
There are two main types of circulatory systems: 1. open circulatory systems and closed circulatory systems. Open circulatory systems are systems where internal organs and body tissues are surrounded by circulatory fluid. This fluid is called hemolymph, and it's pretty much like blood, except that it doesn't contain oxygen transporting cells.
2. The closed circulatory system of some mollusks and all vertebrates and higher invertebrates is a much more efficient system. Here blood is pumped through a closed system of arteries, veins, and capillaries. Capillaries surround the organs, making sure that all cells have an equal opportunity for nourishment and removal of their waste products. However, even closed circulatory systems differ as we move further up the evolutionary tree.
The answer is hydrogen bonds
