Answer: What are the numbers of valence electrons for each atom?
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The cations and anions combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral ionic compound.
The oxidation states are known by their ability to gain or lose electrons which is decided by the number of valence electrons.
The answer should be C. I remember learning about this a few years back. I hope it’s right !
The larynx (plural larynges), colloquially known as the voice box, is an organ in our neck involved in protection of the trachea and sound production. The larynx houses the vocal cords, and is situated just below where the tract of the pharynx splits into the trachea and the esophagus.
I believe the first box would be motor because it describes the automatic reflex. The second box would be brain to spinal cord, because in order for the reaction to happen the brain must first send a signal to the spinal cord for there to be a response from the spinal cord to the muscles.
Answer: A summary on Lac Operon
The lac operon in E. coli contains genes that code for enzymes necessary for the breakdown of lactose. It is expressed only in the absence of glucose is but when lactose is present . It has two regulators turn the operon "on" and "off" in response to the corresponding lactose and glucose levels: they are the lac repressor and catabolite activator protein (CAP).
