I believe it is A because the plant is offering protection while the bacteria is converting it in to nitrogen that the plant can use!
Orbital shell notation of fluorine is 2. 7 while that of oxygen s 2. 6. This means that these elements (that follow each other in the periodic table) will have high electronegativity in molecules due to their high atomic number (which causes them to strongly attract electron orbital shell closer to their nucleus). NB: Atomic number of a peroid increased from left to right of the periodic table.
Therefore, in the first molecule, the negative dipole would most likely be located between the F atoms In the second molecule the negative molecule would be most likely located in the between the O and F atoms.
Answer: b suspension
a suspension is a heterogeneous mixture that contains solid particles sufficiently large for sedimentation . The particles may be
visible to the naked eye, usually must be larger than one micrometer , and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not settled out. A suspension is a heterogeneous mixture in which the solute particles do not dissolve , but get suspended throughout the bulk of the solvent , left floating around freely in the medium. [1] The internal phase (solid) is dispersed throughout the external phase (fluid) through mechanical agitation , with the use of certain excipients or suspending agents.
An example of a suspension would be sand in water. The suspended particles are visible under a
microscope and will settle over time if left undisturbed. This distinguishes a suspension from a colloid , in which the suspended particles are smaller and do not settle.
Colloids and suspensions are different from
solution , in which the dissolved substance (solute) does not exist as a solid, and solvent and solute are homogeneously mixed.
The most appropriate SI unit used to measure the length of a book would be Centimeters.
The most appropriate SI unit to use for the volume of a book is centimeters cubed
