    Variation in sexual reproduction: The event of crossing over occurs during meiosis, which alters the genetic character of the organism. ​After meiosis, the gametes are produced which fuse together to form zygotes. This crossing over leads to variation and the changes in genetic character helps the organism survive in adverse conditions. Therefore, using sexual reproduction the simpler organisms can survive and adapt easily ti the adverse environment.

    Three different nuclear RNA polymerases are found in eukaryotic cells. RNA polymerase I: It is in charge of generating the majority of ribosomal RNA (rRNA) transcripts. RNA polymerase II: It is responsible for converting protein-coding genes into messenger RNA (mRNA). RNA polymerase III: It is responsible for converting rRNA genes into tiny RNAs such as transfer RNA (tRNA) and 5S rRNA.

    Toppr Hershey and Chase performed a series of experiments to prove that the DNA is the genetic material. They took bacteriophages that contained the radioactive sulphur and radioactive phosphorous.  The bacteriophages were then made to infect the bacterial cells and these cells were then studied. The cells that were infected with the radioactive sulphur had protein with radioactive sulphur and not the genetic material. The bacterial cells that were infected with the radioactive phosphorus and phosphorous in the cells. This lead Hershey and Chase to conclude that DNA is the genetic material.

    The sino-atrial (SA) node is a specialized bundle of neurons located in the upper part of the right atrium of the heart. The cardiac impulse originating from the SA node triggers a sequence of electrical events in the heart, thereby controlling the sequence of muscle contraction that pumps blood out of the heart. Since the SA node initiates and maintains the rhythmicity of the heart, it is known as the natural pacemaker of the human body.

    Sewage mainly includes human excreta and contains large amounts of organic waste and pathogenic microbes. Thus it is necessary that waste should be made less polluted before discharging into water bodies. The process of sewage treatment is explained in the following steps: a) Primary treatment - In this treatment, filtration and sedimentation process is applied to remove large and small particles. Filtration process removes the floating debris by passing it through mesh wire screens. Then sedimentation removes the soil and small pebbles. The sediment is known as primary sludge and the supernatant is known as primary effluent. The effluent then enters the secondary treatment. b) Secondary treatment - In this treatment, large aeration tanks containing primary effluent are constantly agitated with a continuous supply of air. Thus aerobic microbes grow vigorously consuming a major part of the organic effluent reducing biological oxygen demand (BOD) of the effluent. The sewage is then passed into the settling tank where bacterial flocs settle and now it is known as activated sludge. Some of the activated sludge is again passed into aeration tank to serve as inoculum while rest of it enters into large tanks called anaerobic sludge digesters. Here anaerobic bacteria grow to produce a mixture of gases such as methane, hydrogen sulphide and carbon dioxide to form biogas. This effluent can then be released into natural water bodies
