When the lac operon controls the expression of proteins in the E.coli cell that can break down lactose into two sugars, glucose and galactose. When lactose is present, it binds to the repressor that typically sits on the lac operon, changing the repressor's conformation such that it can no longer bind to the lac operon. Because of this, RNA polymerase can now transcribe the gene into mRNA, <span>which in turn is translated into the proteins that can break down lactose.</span>
Herbivores is the answer. A heterophic organism that feeds on other organisms in a food chain. Herbivores that feed on green plants and detritivores that feed on decaying matter are primary consumers.
The answer is A, true.
Fungal cells have cell walls which are made out of chitin, unlike plant cells, their cell walls are made up of cellulose.
Other reasons that why fungi are not classified as plants include that because they have no chloroplast, instead they feed on dead organic matters. Another reason is that they store carbohydrates in form of glycogen, instead of plants which store carbohydrates as starch instead.
Answer:
B
Explanation:
They are the closest related.
Terminal velocity is described as a velocity attained when an object which falls freely experiences 0 net force owing to gravitational force which is balanced by the resistance of the air. Hence, there is no acceleration thus, the velocity is constant. In order to attain terminal velocity by the skydiver, the weight of the skydiver must be equal to the resistance of the air hence we have the equation below;
50 kg*9.8 m/s²= 490 Newton.
Summarily, the force or magnitude of the air resistance is 490 Newton
