The atmosphere has five different layers that are determined by the changes in temperature that happen with increasing altitude. Living at the surface of the Earth, we are usually only aware of the events happening in the lowest layer, the troposphere, where all weather occurs.

Explanation:
The rocket is 19.5 m above the ground when h=19h=19:

amp;
amp;Substitute h=19.
amp;Subtract 19.5 on both sides.
amp;Solve for t using the Quadratic Formula.
amp;Simplify.
amp;Subtract.
amp;Evaluate the root.
amp;Find the two solutions.
The rocket will then be at least 19.5 m above the ground for the interval 0.75≤t≤3.25
0.75≤t≤3.25
The only thing here that is capable of causing allergies is an<em><u> allergen</u></em>. Hence the name, it stimulates an immune response to a harmless antigen.
An antihistamine is a substance the prevents the swelling of certain areas of the body due to an increase in histamine production in that area.
An antibody is a type of white blood cell that fights disease.
Bacteria are microscopic organisms that are capable of doing a variety of different things, none of which are pertinent to your question.
I hope I helped!
If you'd like me to elaborate on my response, then just leave a comment down below and I'll gladly do so. :)

Explanation:
The sequence of the nucleotides along the backbone encodes genetic information. The four roles DNA plays are replication, encoding information, mutation/recombination and gene expression.
Basically, this might sound as simple as it can be but new species is a whole set of a new classification of an animal or insect like you have never seen it before type thing. And an Old one is probably something that has been around for many years.
( I'm sorry if this doesn't answer your question if not I would like to help you just have to be a bit more specific. And if I did help that's Great :)
