Insect hormones and their receptors are a focus in pest control and research. Hence, Option B is correct.
Some of the insect hormones such as ecdysone (molting hormone), JH (juvenile hormone) and their analogs can be used for biological control of pests.
Option A: Hormone receptors are proteins that bind hormones and form hormone receptor complex to maintain cellular activities.
So Option A is incorrect.
Option B: Some of the peptide hormones used in pest control and research. So Option B is correct.
Option C: Peptide hormones interact with only cell surface whereas aminoacid derivatives and thyroid hormones directly interact with nucleus. so Option C is incorrect.

Answer:
Use 400 x in order to study the structure clearly.
Explanation:
Cell structures could be clearly identified when magnify the microscope about 400 x by using a compound microscope. Due to high magnification power of compound microscope, the individual is able to see different structures that are present in cells. while by using lower magnification, the individual is unable to see different structures clearly. So use high magnification in order to study the cell.
Chemical elements are important to living organisms because they make up the organic molecules that are found in all living things
The region which is directly medial to the hypochondriac regions of the body is the epigastric region. It is the upper central part of the abdomen, found in between the subcostal plane and the costal margins. This region is part of the nine regions found in the abdomen. The organs included in this region are the pancreas, liver and the stomach. Also, the adrenal gland, a part of the small intestine, the duodenum is also included. This region is not an organ or a muscle rather it is an area of activity wherein the diaphragm and the rectus abdominus would make an outward bulging of the abdominal wall especially the upper portion.
