(I wrote to you more than three types)
There are seven known types of human coronavirus. Four common types (KHUI, OC43, NL63,229E) cause mild to moderate respiratory infection, such as the common cold. There are two types, severe acute respiratory syndrome (SARS-COV) and Middle East respiratory virus syndrome (MERS-COV), that can cause acute respiratory infections. Type VII (nCOV-2019) is the newly discovered novel coronavirus in China.
Answer:
D) Folded mountain with jagged, rough edges
Explanation:
The incident which happened some fifty million years ago was the collision of the Indian plates and the Eurasian plates thus giving rise to the folded mountains that are characteristic of the Himalayas. Subduction was not possible when these two plates collided because they had the same density.
So, the force with which the two plates collided resulted in the formation of folded mountains that rose upward. The peaks of these mountains were jagged, rough, and uneven.
Answer:
c) adrenocorticotropic hormone (ACTH).
Explanation:
A tropic hormone is defined as the hormone which is secreted from one gland and acts on another gland. ACTH is released by anterior portion of our pituitary gland during the condition of biological stress. After it is released, it acts on adrenal gland so that adrenal gland could secrete another hormone named as cortisol (steroid hormone). In response to stress, cortisol increases blood sugar level, elevates brain's use of glucose etc. so as to counter stressful situation.
Apart from this cortisol also helps in regulating our metabolism, reduces inflammation and controls salt and water balance.
