Answer:
n is an even number if and only if it's divisible by 2.
Explanation:
Biconditional statement is a type of statement which is only written when the both segments of the sentence are true. For writing biconditional statement, ''if and only if'' words should be used. For example, the two sides of the triangle are same if and only if both have same length. The biconditional statement considered as true if both the segments are true in nature. Symbolically, it is denoted by double arrows between two symbols.
<span>In transcription, the enzyme that makes the RNA transcript must bind to the promoter region of the DNA before it starts making an RNA transcript. RNA nucleotides will be covalently linked together as the RNA transcript is made. The RNA transcript (also known as pre-mRNA) will be completed when the RNA polymerase reaches the terminator region. After the RNA transcript is released from the RNA polymerase, it will undergo several steps of processing, one of which involves the removal of introns</span>
The giant axon of a squid, shows that hyperpolarizing stimulus is followed by transient inward capacitive current and lasting outward capacitive current.
Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization. It inhibits action potentials by increasing the stimulus required to move the membrane potential to the action potential threshold.
Hyperpolarization can be caused, for instance, by opening channels that allow positive ions to move out of the cell (or negative ions to move in).
The hyperpolarization-activated current is an inward current activated by hyperpolarization from the resting potential and is an important modulator of action potential firing frequency in many excitable cells.

Answer:
Yes.
Explanation:
If the graph line comes lowers from 1999 to 2013 so it means that steps taken by the EPA and the factories were effective in reducing air pollution. The steps taken by the EPA and the factories were effective in reducing air pollution occurs from two pollutants i. e nitrogen oxides (NOx) and sulfur dioxide (SO2) if they install chimneys which collect these gases and reduce pollution. if the factories uses coal having less concentration of sulphur so less air pollution occurs.
The nine major animal phyla in the context of animal phylogeny are Phylum Porifera, Phylum Cnidaria,Phylum Platyhelminthes, Phylum Echinodermata, Phylum Mollusca,Phylum Nematoda,Phylum Arthropoda, Phylum Annelida and Phylum Chordata
<h3>What is animal phylogeny?</h3>
The animal phylogeny is defined as the division of the animal kingdom according to groups which are due to the type of tissue and their various body symmetry.
The type of tissue and body symmetry of the various animals of the nine major animal phyla include the following:
