Which macromolecule provides the blueprint for living things, by storing and transmitting genetic information?

1 answer:

6 0

The nucleic acids (specifically DNA and RNA) are the macromolecule that provides the blueprint for living things by storing and transmitting genetic information.

This is because the genetic information in our bodies is stored in our DNA (deoxyribonucleic acid) undergoes the processes of transcription (where it is transformed into mRNA) and translation (where the mRNA is translated into a polypeptide or protein). These two processes allow the information encoded in our genes to be expressed throughout our bodies through the usage of another macromolecule, the proteins.

Hope this helps!

Explanation:

During a study of lichens and air quality in part of China, scientists measure the thickness of lichens and estimate how many rocks and trees are covered with lichens in one town. The scientists are following the scientific cycle of observing while using a systematic process, establishing facts, explaining facts, and then returning to the systematic process to collect more facts.

Answer:

1. TEF

2.RMR

3.TEA

Explanation:

The major components that contribute to the body daily expenditure are as follows

1. TEF(Thermal effect of feeding)

2.RMR( Resting metabolic rate )

3.TEA(Thermal effect of activity)

Generally resting metabolic rate consume 60 to 75% of energy for maintenance thwe body temperature.

When body is doing this some physical work then it is called activity related expenditure.
