i belive A, i cold be wrong tho, pls tell me if im right if you fully find out
ght. Explanation:
Answer is: beryllium-10.
The diagram shows that atom has 4 protons, 5 neutrons and 2 valence electrons.
Atomic number is the number of protons, which is characteristic of a chemical element, beryllium (Be) is an element with atomic number 4.
Two valence electrons means that atom is from 2. group of periodic table, only beryllium is from that group; sodium (1. group), boron (13. group) and carbon (14. group).
Beryllium-10 has 6 neutrons, so it is isotope (different number of neutrons or mass number).
Answer:
the correct option is : If body fluids are too acidic, carbonic acid is excreted through the respiratory system in the form of carbon dioxide and water.
Explanation:
Metabolic acidosis is compensated by two systems, the renal and respiratory systems.
In the case of the respiratory system, the mechanism it uses to compensate for this phenomenon is to release the carbonic acid molecule dissociated into its components, that is, in the form of water and carbon dioxide.
The greater the acidosis, the more hyperventilation the person will have, and this is because they seek to eliminate carbonic acid more efficiently and quickly, along with renal excision.
The metabolic acidosis generated by carbonic acid is lethal, since the proteins in our body are denatured and the homeostasis of all systems is corrupted.
