Complete the paragraph by choosing the appropriate words given in the brackets : (genetically, recombination, gamete, crossing over, haploid, diploid, Meiosis-II, Meiosis-I, zygote)

………… is just like mitosis. In this stage, the two haploid daughter cells formed in ………… undergo division by separation of recombined sister chromatids and four haploid daughter cells are formed. Process of ………… production and spore formation occurs by meiosis. In this type of cell division, four haploid (n) daughter cells are formed from one ………… cell. During this cell division, ………… ………… occurs between the homologous chromosomes and thereby genetic recombination occurs. Due to this, all the four daughter cells are ………… different from parent cell and from each other too.​

Which of the following describes a negative feedback loop? when the heart rate is too high, the body sends hormones that continually increase the heart rate higher. when a pregnant woman is in labor, the body sends hormones that increase the intensity of contractions, which then increases the secretion of the same hormones. when blood sugar is too low, the body sends hormones that raise blood sugar until it reaches a typical level and hormone secretion slows. when a person is jogging, the body sends hormones that continually decrease the rate of oxygen supply to the legs.

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
