Weakly basic drugs behaves different from acidic drugs which is discussed below.
<h3><u>Explanation</u>:</h3>
Weakly basic drugs are those drugs which have an amine group associated with them. They are able to gain a proton to be come positively charged.
So drugs like quinine, ephedrine and aminopyrine which are basic got completely ionised in stomach.
The stomach can absorb those compounds which are lipid soluble. The acidic drugs like alcohols, Salicylic acid, aspirin, thiopental, secobarbital and antipyrine etc which are acidic gets absorbed by means of <em>diffusion</em> through the membrane.
But the basic drugs have charges on them which makes them lipophobic. So they cannot get absorbed through stomach. However weakly basic drugs sometimes get absorbed depending on their ionisation extent.
The rest goes to small intestine which has basic environment and there they gets absorbed via diffusion or facilitated diffusion.
Explanation:
They put five crickets in each of three identical containers. They s ... to 15°C, one to 20°C, and one to 25°C. Then they count the number of cricket chirps in each container
The sea level would rise by some 50 meters.
Explanation:
If the earth's temperature increases by 3 degrees the north and south pole would experience the ice melt at high speed.
The life will get difficult on the plains.
The extinction of some species will happen.
The sea level would rise by 50 meters. The increased sea level will cause depletion of habitat from plants and animals.
The floods will occur, land erosion, soil for agriculture land will get contaminated with the salt.
Answer:
Metal
Explanation:
In chemistry, an alkali is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element. An alkali also can be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0.
