The difference between a tornado watch and a tornado warning is a tornado watch means that there was a tornado spotted in an area/town nearby. And a tornado warning means that there is a tornado heading towards your town/area or that there already is a tornado in your town/area. Hope this helped!

Answer:
Option A
Explanation:
As per the first equation of equilibrium of Hardy Weinberg, the sum of frequencies of alleles at the locus is equal to unity.
Thus,
If "p" represents the frequency of dominant allele, "q" represents the frequency of recessive allele and at equilibrium
Let us assume that value of q is given in question which is equal to 
On substituting the given values in above equation we get -
Hence, option A is correct
Answer:
Neurons are made up of three major parts: a cell body, or soma The part of the neuron that contains the nucleus of the cell and that keeps the cell alive., which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.
Answer:
Coordinates biofilm formation via chemical signaling among cells. (Ans B)
Explanation:
Quorum sensing in bacteria uses to regulate certain expressions such as phenotype which in turn, coordinate their behavior. Some common phenotype examples are biofilm formation, motility, and virulence factor expression.
Some bacteria have the ability to use quorum sensing to regulate nitrogen fixation, bioluminescence, and sporulation. Quorum sensing regulates genes involved in biofilm development, it helps to promote biofilm dispersion and upregulates the synthesis of surfactant molecules. Quorum sensing and biofilm development are known as social bacterial behaviors.
