The correct answer is A. the change in pH affects the shape and function of the enzyme. It can only function properly in its optimal pH range.
Enzymes are protein molecules and they have a specific shape, which is altered by temperatures and pH that are not within the enzyme's range of operation. This is because the temperature and pH alter the enzyme's structure, which means the shape of its active site is changed and its substrate is not able to fit inside the active site of the enzyme molecule.
This Allows organisms such as bacteria to rapidly adjust their transcription patterns in response to environmental conditions. in addition regulatory sites on prokaryotic DNA are typically located close to transcription promoter sites - and this plays an important part in gene expression
I did this in my class a year ago and as far as i remember it was in the 1700 but i think 1767 to be exact
Flowering plants produce male and female cells. The male cells are called pollen and the female cells are called ova. When a flowering plant is fertilized, it produces offspring in the form of seeds. However, not all plants reproduce flowers. Simpler plants, like mosses, lack these specialized structures.
