Answer:
The correct answer is option b, that is, enteroendocrine cells.
Explanation:
The specialized cells of the pancreas and the gastrointestinal tract exhibiting endocrine function are termed as enteroendocrine cells. These cells generate gastrointestinal peptides or hormones in response to a distinct kind of stimuli and discharge them into the bloodstream for the systemic effect. These are the most varied endocrine cells found within the body.
The intestinal enteroendocrine cells produce somatostatin, cholecystokinin, motilin, enteroglucagon, and neurotensin hormones. The G cells present within the intestine produce gastrin. In the gastric glands, the gastric enteroendocrine cells are present, which produce histamine, and others like cholecystokinin, alpha and gamma-endorphin, somatostatin, and others.
In the islets of Langerhans, the pancreatic enteroendocrine cells are present, which produce hormones like ghrelin, amylin, somatostatin, and pancreatic polypeptide.
Answer:
The result of loss of topsoil are loss in fertility of soil, loss of water, crop production and hardened soil surface. Therefore, the correct answer to the above question is option A, B, C and D.
Explanation:
When there is a loss of top layer of soil from the earth by any means, natural or artificial, it is known as soil erosion. The soil from one place gets detached and is transported to another area. Planting more and more trees is the one of the way to stop soil erosion as the roots of the plants hold the soil.
When the soil from area is removed there is a loss of production in crop due to various reasons. The most fertile part of the soil occurs in the uppermost part. Therefore, its removal has negative impact.
You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there. Neutron numbers are able to change the mass of atoms, because they weigh about as much as a proton and electron together.
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.
option D is incorrect.

Answer:
Losses due to microbial contamination of hatching eggs in the poultry industry can run into millions of Euros. Fumigation with formaldehyde gas is an effective way of disinfection before and during incubation as well as near hatching. In addition, formaldehyde is also hazardous to human health.
