Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement
Explanation:
Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.
For instance:
- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.
- 95% formamide at room temperature would completely denature the double stranded DNA.
Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise

Explanation:
Answer:
<em>Staphylococcus</em> is a gram negative bacteria that belongs under family Staphylococcaceae.The name is given as their body shape is spherical(Cocci).
Explanation:
The important characters of Staphylococcus are-
- <em>Staphylococcus </em>are facultative anaerobic organism.
- They are spherical in shape.
- As they are gram positive bacteria, thus the cell wall is prominant and easily stained with crystal violet and they are grown in bile salts.
- They are capable of producing coagulase enzyme that cause blood clot.
- These bacteria divides along two axes and thus form clump of bacteria.
Difference between <em>S. aureus</em> and <em>S.epidermis-</em>
- <em>S. aureus</em> is round in shape where as<em> S.epidermis</em> is spherical in shape.
- <em>S. aureus</em> is a opportunistic pathogen that cause different diseases like skin infection where as<em> S.epidermis</em> is non pathogenic bacteria.
- <em>S. epidermis</em> form white raised cohesive colony with 1-2 mm in diameter whereas, <em>S.aureus</em> form golden yellow color colony.
- <em>S.aureus</em> causes hemolysis when it is grown in agar plate whereas <em>S.epidermis</em> is not hemolyse in blood agar plate.
Answer:
A GMO Genetically Modified Product though similar to cloning is quite different. Cloning is the process of using egg cells from an individual to produce a new organism. When the baby is born, it is genetically identical to the parent, an exact copy. This process occurs in a lab. Genetic Engineering, which is used to make GMOs, uses technology to alter or change an organism's genes. New genetic information can be added to or removed from an existing set of DNA.
<em>So I would say that some of the differences between GMOs and cloning include that:</em>
Cloning strives to create exact copies of an organism's parent while GMOs remove and add different genes to form desired offsprings like making a product last longer or making the product grow larger faster.
Hopefully, this helped you! Have a nice day :)
