**Step-by-Step Solution:** 1. **Soaking the Seeds:** The student soaked seeds of green gram, wheat, maize, peas, and tamarind in water overnight. This process allows the seeds to absorb water, which can lead to swelling and changes in their structure. 2. **Observation of Changes:** After soaking, the student observes that the seeds have swollen. This swelling occurs due to osmosis, where water moves into the seeds, causing them to expand. 3. **Attempt to Split the Seeds:** The next morning, the student tries to split the seeds into two nearly equal halves. ...

First read a passage and then answer the questions following that passage. Soil scientists have shown that the soil teems with millions of living things, many of them useful, others harmful. The living things which are useful include earthworms and various kinds of bacteria. Earthworms loosen the soil and so enable air and water to enter it. Bacteria, which are microscopic living things break down dead plants and animals and make humus, or take nitrogen from the air and change it into substances that plants use. The living things that do harm include other bacteria and fungi which cause diseases. Other harmful things are pests such as wire worms which feed on the roots of grass and other plants. While the farmer can usually keep weeds in check by careful cultivation, this alone may not protect his crops from insects, pests and diseases. Nowadays, however, he is much better able to control these enemies. He may plant. specially resistant types of seeds or he may keep the pests and diseases in check with chemicals. With better seeds farmers have been able to increase their crop yield . They can grow crops that ripen more quickly and have a stronger resistance to disease, frost or drought. The farmers today can also select seeds

After winning the challenge fair and square, and winning a Snorlax, Max finally reaches Viridian City. As he enters viridian city, he notices that there is a Pokémon trainer in front of the gym. I will only let you pass if you beat me in my favourite game, he says. This is a game played with a sequence of tiles, each labelled with two numbers. You start at the first the in the sequence and choose one number from each tile that you stop at, according to the following rules: • At tile i, if you pick up the smaller number, you move on to the next tile, i+1, in the sequence. • At tile i, if you pick up the larger number, you skip the next tile and move to tile i+2 in the sequence. The game ends when your next move takes you beyond the end of the sequence. Your score is the sum of all the numbers you have picked up. For example, suppose you have a sequence of four tiles as follows: Then the maximum score you can achieve is 3, by choosing the numbers that are circled. Now, you are given the following tiles. What is the maximum score you can make to ensure you beat the security guard?
