Answer:

The correct answer is - 2n = 41 chromosomes.

Explanation:

It is given that the cat has a diploid chromosome number of 38 while the rabbit has a diploid number of 44 chromosomes and if they form a hybrid then their expected chromosome number in somatic cells would be -

Cat (2n=38) produces haploid gametes with 19 chromosomes (n-19).

Rabbit (2n=44) produces haploid gametes with 22 chromosomes(n=22)

19+22= 41 chromosomes in the particular hybrid as half number of chromosomes come from each parent.

Here’s one! Huge farming companies genetically modified foods to withstand round up. You might know round up as a weed killer. It’s marketed safe with no harming chemicals to humans. That is completely wrong and have been proven to cause many chronic illnesses including cancer. These foods are modified to not react with round up and only to kill the weeds all around the plants. Even though the food looks ok it’s really not. The round up is all over the food. Then we eat it and well bad chemicals get absorbed into are body.

I hope this is some of what you were looking for. If not I hope you enjoyed my fun fact ;) good luck.
