The wax glands in honey bee are present ..............

  1. On the ventral side of the last segment.

  2. On the ventral side of last four abdominal segments.

  3. On the dorso-lateral side of first two abdominal segments.

  4. On the lateral side of last two abdominal segments.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Four sets of wax glands, situated inside the last four ventral segments of the abdomen, produce wax for comb construction. Wax bees build cells from wax, repair old cells, and store nectar and pollen brought in by other workers. Early in the worker bee's career, she will exude wax from the space between several of her abdominal segments.

  1. D only

  2. A & D

  3. A,B & C

  4. A,B,C & D
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Answer is option (D) 

Parietal cells (also known as oxyntic cells) are the epithelial cells that secrete hydrochloric acid (HCl) and intrinsic factor. 
Peptic cells are also known as zymogen cells releases pepsinogen and chymosin. It means all cells given in the option belongs to stomach epithelium and the part of tubular gland.

Which of the following gland is partly exocrine and partly exocrine?

  1. Pituitary

  2. Thyroid

  3. Pancreas

  4. Hypothalamus
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Pancreas acts both as endocrine (ductless) and exocrine (with duct) gland. It works as exocrine gland as it excretes enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food and helps in digestion. It works as endocrine gland as it secretes the hormones insulin and glucagon to control blood sugar levels throughout the day. 
Hence option C is correct.

Acini cells are

  1. Endocrine

  2. Exocrine

  3. Both endocrine and exocrine

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

There are two types of cells in the pancreas, the acinar cells and the islet of Langerhans. The acinar cells are lobed cells. These cells are responsible for the exocrine function of the pancreas. They secrete the pancreatic enzymes and forms the pancreatic juice which is involved in the process of digestion.

Thus, the correct answer is option B.
