4. Question
Which of the following reasons associated with the Flash Droughts?
1. Long-term monsoon breaks
2. low precipitation
3. abnormally low temperatures
Which of the statements given above is/are correct?CorrectAns;- a) Only 1 and 2
Explanation;-
• The 3rd is incorrect it is abnormally high temperatures.
• Recently More flash droughts in India by end of centuryAbout Flash Droughts
• Flash drought refers to relatively short periods of warm surface temperature and anomalously low and rapid decreasing soil moisture (SM).
• Based on the physical mechanisms associated with flash droughts, we classify these events into two categories: heat wave and precipitation (P) deficit flash droughts.
• A drought is caused by drier than normal conditions that can eventually lead to water supply problems.
• Really hot temperatures can make a drought worse by evaporating moisture from the soil.
• A drought is a prolonged period with less-than-average amounts of rain or snow in a particular region.
• Long-term monsoon breaks prolonged dry spells during the season are leading to a unique phenomenon called flash droughts in India, affecting kharif crops and groundwater depletion, according to a new study by researchers at the Indian Institute of Technology (IIT)-Gandhinagar.
• Flash drought intensifies rapidly due to changes in precipitation, temperature, wind, and radiation.
• These changes in the weather increase evapotranspiration and lower soil moisture.IncorrectAns;- a) Only 1 and 2

5. Question
Which of the following statements are correct regarding the general difference between plant and animal cells ?
1. Plant cells have cellulose cell walls whilst animal cells do not.
2. Plant cells do not have plasma membrane unlike animal cells which do.
3. Mature plant cell has one large vacuole whilst an animal cell has many small vacuoles.Select the correct answer using the code given below :
CorrectAns;- c) 1 and 3 only
Explanation;-
• Both animal and plant cells have mitochondria, but only plant cells have chloroplasts.• Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast.
• Once the sugar is made, it is then broken down by the mitochondria to make energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
• Both plant and animal cells have vacuoles. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles.3 is correct.
• The Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall. 1 is correct.
• The Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not. 2 is incorrect.
