The right coding strand for this will be:

Primary productivity does not depends on :

Failure of chromatids to segregate during cell division cycle results in :

Read the following paragraph and answer the given questions.
Bio-fertilisers are organisms that enrich the nutrient quality of the soil like cyanobacteria, while there are organisms that help to control plant diseases and pests. The very familiar beetle, the ladybird and dragonflies are useful to get rid of aphids and mosquitoes, respectively. An example of microbial biocontrol agents that can be introduced to control butterfly caterpillars is certain bacteria, which are available in sachets in the form of dry spores. These spores are mixed with water and sprayed onto vulnerable plants. Trichoderma species that are very common in the root ecosystem, are very effective biocontrol agents of several plant pathogens.Baculoviruses attack insects and other arthropods. Usage of these viruses is desirable when an ecological sensitive area is being treated.
Which one of the following is used to control caterpillars of butterflies?

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.
Alcohol lengthens the time one takes to respond to a stimulus. This occurs due to

Read the following passage carefully and answer the given questions.
Productivity in the Ecosystem
The flow of energy through a terrestrial ecosystem starts with the harnessing of sunlight by autotrophs. The radiant energy is converted by photosynthesis to organic compounds is known as productivity. The productivity is expressed in units of energy per unit of area per unit time. The amount of organic matter present at any given time is biomass. The productivity of any ecosystem is affected by many parameters like weather conditions, nutrient availability etc. The productivity of any ecosystem does vary seasonally and yearly.
The unit for expressing productivity is -

If the matrix A = \(\left[\begin{array}{cc}\cos \theta & \sin \theta \\ -\sin \theta & \cos \theta\end{array}\right]\), then \(A ^2\) is equal to:

A. \(\vec{a}\) and \(-\vec{a}\) are always collinear.
B. Two collinear vectors are always equal in magnitude.
C. Two vectors having the same magnitude are equal.
D. Two collinear vectors having the same magnitude are equal.
E. If \(\hat{p}\) is a unit vector along line \(l\) then the projection of vector \(\vec{a}\) on line \(l\) is given by \(\vec{a} \cdot \hat{p}\)
Choose the correct answer from the options given below:

The above reaction is an example of

Two point charges \( q_1 = 36 \text{ }\mu\text{C} \) and \( q_2 = -9 \text{ }\mu\text{C} \) are placed at a distance of 30 cm. The distance from \( q_1 \) where the net electric field is zero, will be :
