Answer-The answer is B Thermal energy

Explanation- The energy associated with the random motion (kinetic energy) of molecules or atoms within a substance is thermal energy. This energy can usually be calculated from temperature measurements. As a sample gets hotter, its thermal energy increases.

I think B. thermal energy.
When we heat up a substance, we increase the motion or vibration of the particles.

Reika [66]

The option are not given and the options are:

Proteins are denatured by breaking covalent bonds.

Linear molecules like DNA are inherently stable.  

Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.

The statement is incorrect; it actually takes far more energy to denature proteins than it does to denature DNA.

Answer:

The correct answer is- Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.

Explanation:

Proteins become denatured when it looses its three-dimensional structure. Disulfide bond and hydrogen helps in stabilizing the three-dimensional structure of proteins and if these bonds break due to any factor protein lost its structure and function.

DNA is made up of a large amount of hydrogen bond because in AT base-pairing two hydrogen bonds are required and in GC base pairing three hydrogen bonds are required. Therefore it can be concluded that as more hydrogen bonds stabilizes DNA than protein its melting temperature is higher than protein.

You have a strand of DNA with the nucleotide sequence AGATCGATT. The complementary strand will have which of the following seque
enot [183]

Answer:

The answer is B

Explanation:

with complementary strands A goes with T

and G goes with C

   so         AGA TCG ATT

becomes TCT AGC TAA

you can see how you swap A's with T's and C's with G's. and vice versa.
