Negative feedback helps maintain a set point or ___ in biological systems.

Describe a real-life example of negative feedback in the human body and explain its significance.

Explain the difference between positive feedback and negative feedback in biological systems. Why is negative feedback important for maintaining homeostasis?

Why is feedback regulation important in biological systems?

The periodic symbol "C" stands for the element​ (a)   . Its atomic number on the periodic table is​ (b)   , due to the fact that it has​ (c)   protons and​ (d)   electrons. The most common isotope of Carbon is Carbon-12 (a mass number of 12), which means it most often has​ (e)   neutrons in its atomic nucleus.

When two identical atoms, such as two oxygen atoms, bond, the resulting bond is​ (a)  

If an atom of oxygen gains two electrons, how many protons and electrons does it now have? What is its ionic charge? Atomic Mass?
