Posted by Anchal Leel 5 years, 5 months ago

? Pranali.A.P ? 5 years, 5 months ago

Since image distance is 40 cm from the mirror, object is at the same position and thus at 40 cm from the mirror. When the object is moved 20 cm towards the mirror, then it is at Focus of the mirror (since 2F = 40) . In this case the image is formed at infinity.

ANSWER

name the gland which is endocrine as well as exocrine .

Posted by Lucifer ? Morningstar? 5 years, 5 months ago

CBSE > Class 10 > Science

5 answers

Gaurav Seth 5 years, 5 months ago

Ans: pancreas

Explanation:

The pancreas is a glandular organ in the upper abdomen, but really it serves as two glands in one: a digestive exocrine gland and a hormone-producing endocrine gland.
Functioning as an exocrine gland, the pancreas release enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food.
Functioning as an endocrine gland, the pancreas secretes the hormones insulin and glucagon that control blood sugar levels.
Both of these diverse functions are vital to the body’s survival. Adrenal, Thyroid, and Pituitary glands are endocrine glands that only secrete hormones.

Yogita Ingle 5 years, 5 months ago

Alveoli are covered with blood capillaries so that the exchange of gases can take place between the membranes of the alveoli and the surrounding capillaries. The blood capillaries covering alveoli have a low oxygen and high carbon dioxide concentrations. This allows oxygen to diffuse into the blood and carbon dioxide to diffuse out of the blood.
