Ok, particle is not a very nice word, no real sense of size associated with it
it can be a group of molecules like a speck of sand
referring to the molecules themselves
or refering to the atoms that make up the molecule
now in terms of phase change,
if we consider a speck- a group of molecules- then solids will expand when heated, however this definition falls flat in terms of phase change
ok, how about molecules, as molecules undergo phase change, the molecules in relation to each other will move apart from one another. Solid- molecules are bonded, Liquids- molecules are close and flow around each other, Gas- molecules are a significant distance from one another. But the increase in size when you heat up a molecule, i would have to say yes. adding heat increases energy which increases molecular vibration which would probably increase the overall average size to some unnoticeable degree.
now standalone atoms are just atoms, if you want to consider the electron cloud as size, then heating it up would negligibly cause the outer move outward. but it really depends on the scale of the question
Answer:
The vector, that is , the bacterium is encoded by the antibiotic resistance gene.
Explanation:
A recombinant organism is the organism that its genetic makeup has been altered, this means , the organism contains different combination of alleles, that can't be found in either of the parents. This is usually done by deliberately introducing new genetic materials or elements.
The offspring produced by these altered organisms also possess the new genetic material that was initially introduced to the altered organisms.
Bacteria have been the most desired organism for this act, because they are easy to grow and nurture.
The answer is Devonian.
Devonian is also known as the age of fishes.Devonian is named after the word Devon, a country somewhere south western England. This age of fishes began the domination of the fishes.
Bacteria and archaea are the domains that only include prokaryotes :)
Answer:
B
Explanation:
It occurs when water dissolved with salts seeps into the cracks of a rock. When the water slowly evaporates it leaves behind crystals of salts. When the rock is heated, the salts also expand and create pressure within the cracks, widening them and causing the rock to split.
