The carbon cycle ensures that carbon is not lost. which is another important benefit of the carbon cycle? a-the carbon cycle regulate earth's temperature. b- the carbon cycle ensures that living things have a continual source of hydrogen. c- the carbon cycle transport nutrients in bodies of water. d- the carbon cycle ensures that there is a continual supply of water.

The right option is; B- The carbon cycle ensures that living things have a continual source of hydrogen.

The carbon cycle is a process that describes how carbon compounds moves between living organisms and their environment.  Carbon is an important element and the fundamental building block of all living organisms. The carbon cycle ensures continual availability of other elements and compounds such as hydrogen and oxygen. Carbon is mainly available in the atmosphere as carbon dioxide, and also less available as important gases, such as methane (hydrocarbon). In living organisms, all hydrogen apart from the one present in water is in form of hydrocarbons.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:

the index of refraction of the second medium is higher. i just took the test trust me !
