Motion of Particles in Solids
Solids have a definite volume and shape because particles in a solid vibrate around fixed locations. Strong attractions between the particles in a solid restrict their motion, keeping them in place.

What is poisonous enough to kill 100,000 turkeys? That’s the question asked by scientists who studied a mass die-off of turkeys
Eduardwww [97]

Answer: The best way for farmers to prevent fungi from growing is to make sure there is not enough  moisture for fungi to survive and grow

Explanation: Fungi require moisture or water for a wide number of reasons. One of the best guesses I can give as a reason to why they might need it is to help them in the process of digestion. Fungi use digestive enzymes which are specially shaped proteins that break down macromolecules like glucose or cellulose and a number of other biological molecules, and they do this through one of two processes, dehydration synthesis, or hydrolysis. Hydrolysis in particular is the one that requires water. It uses pieces of water to break a bond between complex sugars and carbohydrates among other molecules, to separate them into smaller and easier to absorb monomers which are the subunits that make up the molecule. It breaks apart the water and uses the pieces to fill in the gaps of the pieces the monomers used to share.

If thymidine dimers created by UV irradiation persist until DNA replication, DNA polymerase is likely to make a mistake reading
marishachu [46]

Answer:

Thymidine dimers is likely to be repair as soon as it is originated but if left unrepaired then it causes  frame shift mutations.

Explanation:

In case of Bacterium if UV irradiation induces covalent linkage of two thymidine present adjacently to each other or on a single strand to make thymidine dimers.

These either excised via DNA repair enzyme like Endonuclease V and the proof reading activity of DNA polymerase I enzyme help in incorporation of nucleotide by taking the unmutated original strand as a template.

These dimers if not excised before second round of replication than the sequence of newly synthesized strand will be altered. As DNA polymerase III enzyme read thymidine dimers as single thymidine nucleotide and incorporate only 1 adenine in the newly synthesizing complementary strand which results in frame shift mutations

It is the mutation in which reading frame of codons is shifted or altered due to deletion or addition of a single nucleotide.

Which two adaptations of herbivorous enables them to digest cellulose​
Anestetic [448]

Answer:

Cellulose Digestion in Herbivores

By means of the symbiotic gut bacteria, cellulose can be digested by herbivores with the help of monogastric digestion. Herbivores are less efficient than ruminants in the case of extracting energy from the digestion of cellulose. Here, cellulose is digested by microbial fermentation.
