The DNA is mostly because the hyperchromic effect is very . The fact that there is any hyperchromicity at all means that there may be a amount of intramolecular base-pairing. a. greatb. largec. double-strandedd. smalle. single-stranded

Option C,D and D.

1. C 2.D.3.D

Explanation:

DNA, deoxyribonucleid acid is the genetic material or component of living organisms . It has two two chains that coil around each other to form double helix structure. It is found in the nucleus because it is small and the cell itself is small.DNA have two base pairs and carries genetic information for growth, reproduction, functioning and development.

The DNA is double stranded, the hyperchromic(,its ability to absorb light)effect is small, and there are small amount of molecular base pairing. The hyperchromic effect of DNA is the ability of DNA to absorb light at night temperature. The double stranded DNA is heated at high temperature,and it unwind to single stranded DNA which have the ability to absorb light.

answer: blah

explanation:

bc blah

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
