I am testing the effect of the amount of water on corn plant growth. Group 1 has sunlight, a pot, soil, and water every day. Group 2 has sunlight, the same pot, the same soil, and water only once in the week. After one week, I measure the plant height of both groups. What is a control variable? O Plant height O Amount of water One week Sunlight

Homeostasis

Homeostasis is a self-regulatory process through which different biological systems maintain constant internal environmental conditions to compensate for environmental changes. In human physiology, it is a process of self-regulating internal, chemical, and physical conditions at an optimal level for survival. The stability through homeostasis can be attained through dynamic equilibrium, in which there is a continuous change until it reaches its systemic conditions.
