Glycogen.
Glycogen is a multibranched polysaccharide that serves as a form of
energy storage in animals. They're stored inside the liver and muscles.
I think the answers are 1) Hox genes
2)B But I'm not sure
Answer:
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium.
Explanation:
The correct answer is A. When free hydrogen ions and free hydroxyl ions are removed from solutions of acids and bases, the acidic and basic properties disappear.
The strength of the acid or base depends upon its degree of ionization. Since different acids and different bases dissociate or ionize to different extent in water so their degree of ionization is also different. Strong acids and strong bases ionize in water completely while the weaker acids or bases ionize partially. Ionization of the weak acids in water are in equilibrium. The degree of ionization is the ratio of the number of ionized molecules to the number of molecules which are dissolved in water. In case of acids the ionized molecules are hydrogen ions and in case of bases hydroxyl ions.
The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.
