Vaccination involves showing the immune system something which looks very similar to a particular virus or bacteria, which helps the immune system be stronger when it is fighting against the real infection.
Explanation: "it is what it is".
The two basic reaction types are synthesis and decomposition. ... Decomposition reactions are the opposite of synthesis reactions because they take apart larger molecules and/or compounds. The generic equation for a synthesis reaction is A + B à AB, where A and B are the pieces that make up the compound/molecule AB.
A. objects made of crystals minerals water and air
Process of elimination-
there isn’t organic matter in rocks so D is out
they are made of minerals so B is out
some types of rock (pumice) have air bubbles in them so A is more likely than C
<h2>Answer is option "B"</h2>
Explanation:
- Fossils are formed by unusal ways of minerals,energy and other substances. the sap solidifies and frames the semiprecious material called golden. In certain bits of golden the buried survives from living beings can be found. Volcanic ejections can shape fossils when creatures get caught in the hot debris streams. Right now, the fossil is a hole looking like an animal.
- Truth be told coal is the fossil record of entire timberlands; in any case, singular plant structures normally don't make due as the plant materials are compacted to short of what one-hundredth of their unique size. the hard part of plants are remain the fossil.
- So as to get fossilized, creatures must kick the bucket in a watery situation and become covered in the mud and residue.
- hence, the right answer is option B "Plant lived near the poles,but landmasses have drifted to current locations".
