The correct answer is: B) continuous transcription of the structural gene controlled by that regulator
A regulatory gene is gene that encodes for a protein, such as a repressor (or activators) that controls the transcription of another gene or group of genes.
The regulatory gene of a repressible operon encodes for the repressor that inhibits gene transcription. So, when that repressor isn’t active, transcription occurs continuously.
Answer: B soil is also called the SUBSOIL.
Soil horizon consists of layers of soil that differ physically. It contains 3 or 4 layers or horizon such as O horizon, A horizon, B horizon, C horizon and R horizon. B horizon is also referred as subsoil. It is yellowish to brown in color. It consists of mineral layers such as silicate clay, iron, aluminium, gypsum, silica, humus, etc. The roots of a plant penetrates through the subsoil.
number 8 is b because when you eat plants or animals, it get transfred to glucose which is then transfered to atp. Think about it this way, when you are sick, you dont just go outside in the sun to recharge and then you suddenly get better, and energy, you have to rest and eat certain foods that will restore your ATP levles.
