Which of the following is a tool that measures an individual's impact on the environment? a. food production b. global hectare c. ecological footprint d. biocapacity

C. Ecological footprint

Explanation:

The ecological footprint can be define as the total amount of biological productive area required by the human beings so as to produce goods and service and to lead a healthy lifestyle. It also measures the amount of wastes generated after the use of natural resources and the impact of the human society on the surrounding environment in order to generate goods and availing services.

On the basis of the above explanation, ecological footprint is a tool that measures an individual's impact on the environment.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
