Answer:
The net money the farmer will get
= Rs. 39,500
Explanation:
The farmer bought 5 kg seeds of rice at Rs. 100 per kg.
Cost price = 5 × 100 = Rs. 500
And he plants them and harvests 1000 kg of rice grains for sale, which he sells for Rs. 40 per kg
Selling price = 1000 × 40 = Rs. 40,000
The farmer's net profit
= (Selling Price) - (Cost Price) = 40,000 - 500 = Rs. 39,500
Hope this Helps!!!
A, D, and F because if biotic once it dies it doesnt lose the biotic factor.
Plants make their food in their leaves. And need sun for this process, so smaller and fewer leaves means less sun for photosynthesis, and it also means less food to nourish the plant.
Answer:
Please find the detailed explanation of this statement below
Explanation:
Firstly, a repressed gene is a gene whose expression has been inhibited or repressed. The lac operon in E.coli bacteria is a regulatory unit containing structural genes, a single promoter and operator regions. The promoter is the region where the transcription enzyme (RNA polymerase) binds to in order to transcribe the genes in the lac operon. The structural genes in the lac operon can only be expressed in the presence of lactose sugar.
However, in the absence of lactose, LAC REPRESSOR, which is a transcription factor (protein), prevents the binding of RNA polymerase to the PROMOTER region by binding to the OPERATOR region of the lac operon. This inhibits the expression of the lactose genes in the operon.
Note that, the structural genes in the lac operon (lacZ, lacY, lacA) code for proteins that help break down lactose sugar for energy in the E.coli bacteria. Therefore, a bacteria cell with a repressed lac operon will be unable to degrade lactose sugar.
