C) <em>The frequency of heterozygotes is given by (p + q)/N, where N is the number of individuals in the population.</em>
The correct answer is A. Lac repressor.
Lac repressor prevents lac gene which are found in the DNA of Escherichia Coli from being expressed for many times.
Lac repressor is termed as DNA which binds proteins. It allows the expression of genes from coding which are made for proteins to be involved in metabolism of lactose which is in bacteria.
When there is no lactose which is available in the cell, then the genes are being repressed. Lactose are being converted to allolactose if they are available.
The rose population would decrease because the bees would need more food.

The sun would stay the same because it is an abiotic factor in an ecosystem. your welcome fam
