Answer:
Let's pick six liquids randomly, i.e. honey, corn syrup, whole milk, water, vegetable oil, rubbing alcohol, and put them in a beaker. The higher density liquid will take the bottom position whereas lower density liquids will be on above of high density liquids. 
We know that honey has density (g/cm3) of 1.42, dish soap has 1.06, corn syrup has 1.33, milk has 1.03, water has 1.00 (standard), and vegetable oil and 0.92. Therefore, honey will be at the bottom most position (rank #1). Above which would be corn syrup (rank #2), dish soap (rank #3), milk (rank #4), water  (rank #5) and vegetable oil (rank #6). 
The results might be surprising for some students who think that water has highest density.
 
        
             
        
        
        
Answer:
Option (3).
Explanation:
Teratogens may be defined as the chemicals that can cause birth defects in the fetus. Substances like alcohol, lead and nicotine acts as the main agents of tertaogens.
Shamona is drinking water that contains high level of lead. The element lead is harmful for the fetus. Even the small concentration of lead is enough to cause birth defects. The lead exposure can cause the abnormal development of brain and damages the brain of fetus. The fetus has low birth weight also.
Thus, the correct answer is option (3).

Answer:
The term secretion refers to the cell that releases a substance into the extracellular space.
Explanation:
When a cell or organ or gland produce and secretes substance in to extracellular space,this biochemical process is called as secretion.
The secretory products may be hormone, enzymes etc.
This process facilitates the movement of material from one place to another place.
For example, Pituitary gland produce and release prolactin hormone that induces breast cells to produce lactation during sucking process done by baby.
Pituitary gland also secrete different hormones that acts on different glands like adrenal, testes, ovary, thyroid gland etc that in turn produce different hormones like adrenaline,testosterone,estrogen,progesterone, TSH,T3, hormone etc.
