Which type of RNA functions as a carrier of the genetic code?
gayaneshka [121]

All forms of RNA are intermediate molecules that are fabricated within DNA to perform cellular functions.

mRNA - messenger RNA carries selected portions of DNA used to fabricate polypeptides used to fabricate amino acids for protein.

tRNA - transfer RNA is comprised of select genetic code and transfers amino acids to ribosomes for assembly

rRNA - ribosomal RNA is comprised of select genetic code and makes the ribosomes

RNA is highly mutatable, highly reactive, non-reproductive, and highly specialized metabolically, and consequently totally unsuitable for consideration of any pre-DNA senario being posited for the origin of life.

vovangra [49]

Answer: c. The Earth’s surface is responsible for a small fraction of heat radiation to space.

Explanation:

In later ages the large amount of sun's energy is reflected back by the terrestrial surface back to the space. But now due to the abundance of large concentration of greenhouse gases in the atmosphere is responsible for the absorption of thermal energy from sunlight by these gases causing the atmosphere to be hot. This is the reason of global warming. Now only small fraction of heat is radiated back to the space.

Please help me with my question I will like and mark as brainliest ​
Ilia_Sergeevich [38]

Answer:

During exercise your cells need energy to function. in order to do so they harness it through ATP. In order to get ATP the cells convert it to ADP usually through aerobic respiration. Aerobic respiration requires oxygen to function and the cells will use up all their oxygen stores for it. Cells will get more oxygen when the exercise has been completed through the pulmonary system delivering oxygenated blood to the cells and taking away the used CO2 rich blood.
