Answer:
Non-random alignment of chromosome pairs.
Explanation:
Meiosis is when the mother cell or the diploid cell replicates into four haploid cells and divides twice; leaving just two haploid cells that contains only half the number of chromosomes.
Through meiosis, we get the gametes which are the cells that we use to fecund and reproduce ourselves (ovules and sperm); each cell contains half the chromosome content. To allow the combination of genetic information by cross-linking the chromosomes there need to be 23 chromosomes from the father and 23 from the mother to form one individual with 46 chromosomes.
Leaving us with non-random alignment of chromosome pairs as if it was random that would mean that it wouldn’t matter how many chromosomes each parent provides, also, the cells have to be haploid in order to continue the process.
More than 3000 children die each day due to contaminated water.
More than a quarter of children under 5 years of age die from unhealthy environments. Every year, environmental hazards - such as indoor and outdoor air pollution, secondhand smoke, unsafe water, lack of sanitation and inadequate sanitation - kill 1.7 million children under the age of 5. , according to two new WHO reports.
First report, Inheriting a Sustainable World: Atlas of Child Health and the Environment shows many of the most common causes of death among children 1 month to 5 years old - diarrhea, malaria and pneumonia – can be prevented with interventions that reduce environmental risks, such as access to clean drinking water and cooking fuels.
“A polluted environment can be deadly, especially for young children,” said Dr. Margaret Chan, WHO Director-General. "Their developing organs and immune systems, along with their smaller bodies and respiratory tracts, make them particularly vulnerable to dirty air and water."

Answer:
i would say Yoyo is frustrated by her inability to write a good speech for the assembly at her school.
Explanation:
Because of these sentences: "But not even a sibyl could have made sense of those tiny scraps of paper. All hope was lost. "He broke it, he broke it," Yoyo moaned as she picked up a handful of pieces."
As you can see the paragraph says "but not even a sibyl could have made sense" so the author is giving you the sense of she wants the speech to be good and to make sense. And it also said "All hope was lost" sooo.
I honestly dont actually know if what i just said makes any sense but i hope this helps
Answer:
Intelligence tests should play no role in grading or marking practices
Explanation:
This is because practice is an exercise or test on its own, and there should be a level playing field for every participant regardless of their IQ level prior to taking the practice. Hence, in this case, the right answer to the question is "Intelligence tests should play no role in grading or marking practices of participants," as this may lead to bias from the examiner.
