Answer:

You did not put the answer options, but I can help you by stating that the scale of agriculture today is large-scale agriculture and it can be defined by a term that presents large farms with extremely high productivity.

Explanation:

The scales of agriculture are measured through the agricultural productivity achieved through work in the agricultural sector. Small-scale agriculture is one where productivity is low, the farmer does not produce as many products and most of them are harvested for family consumption, becoming a type of subsistence agriculture.

Large-scale farming is what we can see today, they are characterized by very large farms that promote high productivity, producing thousands of products in the shortest possible time.

Answer:

transcription initiation

Explanation:

Transcription is a process by which genetic information from DNA is used to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently utilized to synthesize a protein by a process called translation. Transcription in prokaryotes has three steps:

1-Initiation: the RNA polymerase is a multisubunit enzyme (holoenzyme) composed of two α, one β, one β’ and one ω and σ subunits (α2ββ’ωσ). This holoenzyme binds to the promoter region of the template DNA strand.

2-Elongation. The sigma σ factor of the holoenzyme is released and the complex and the core enzyme (α2 ββω) moves along the template strand, thereby producing an mRNA sequence

3-Termination. This step can be Rho-dependent, where a protein named "Rho" recognizes the termination site and stop transcription, and Rho-independent (transcription continues until the termination sequence is reached).

In consequence, Rifamycin is likely to block the initiation of transcription because the core RNA enzyme needs to bind the sigma factor (σ) for initiation of transcription in bacteria.

Lead emission since early 1980s have DECREASE DUE TO LEAD FREE GASOLINE. 
Lead is a natural occurring element that is found in small quantity in rocks and soils. Lead emission is an important environmental health issue because a very small quantity of lead can cause adverse effects on the nervous system of unborn babies and young children. Because of this, the government took all necessary measures to ensure that its emission was drastically reduced.
