Choose the correct answer from the options given below :

Alcohol is a depressant, which means that even small amounts of alcohol slow down the actions of parts of the brain, so alcohol lengthens the time you take to respond to a stimulus.
Different people react differently to alcohol. In some people, it increase their feelings of aggression, and releases their inhibitions so that they are more likely to be violent or commit other crimes.
An alcoholic needs to drink quite large quantities of alcohol regularly. This causes many parts of the body to be damaged, because alcohol is poisonous to cells. Probably, there are many factors which decide whether or not a person becomes alcoholic. Over a long period of time, it can cause loss of memory and confusion. One way in which the damage is done is that alcohol in the body fluids draws water out of cells by osmosis.
Identify the measure which is not useful for prevention and control of alcohol abuse among adolescents.

Which one of the following plants is the source of cannabinoids commonly used in drug abuse?

Identify the incorrect statement about the human genome -

Population density at time t + 1 is typically expressed as:
\(N t+1=N t+(\{B+I\}-\{D+E\})\) where \(B+I\),

A charge of \( 20\mu C \) lies at the centre of a square. Work done in carrying a charge of \( 5\mu C \) from one corner of the square to the diagonally opposite corner is :

MONOHYBRID CROSS
The inheritance of flower color in the dog flower (Snapdragon or Antirrhinum sp.) can be understood by crossbreeding between true-breeding red-flowered (RR) and true-breeding white-flowered plants (rr). When they were crossed, F₁ (Rr) was pink. When F₁ was self-pollinated, the F₂ results were Red, Pink and White. Here the genotype ratios were exactly as expected, but the phenotype ratios have been changed. What happened was that R was not completely dominant over r and this made it possible to distinguish Rr as pink from RR (Red) and rr (White).
In the above passage, the inheritance is an example of:

If \(\int e^x\left(\frac{x-1}{(x+1)^3}\right) d x=\frac{A e^x}{(x+1)^B}+C\), where \(C\) is constant of integration, then which of the following are correct?

(B) \(A=1\)
(C) \(B=3\)
(D) \(B=2\)
