The correct answer is - Since 2000, more people are living with HIV, but fewer people are dying from AIDS.

Since the year 2000, the number of people that are living with HIV has been steadily increasing, though it has to be noted that the rise has been gradually slowing down. On the other hand, despite having more living with HIV, the deaths by AIDS have reduced gradually.

The main reason for the increase of people living with HIV is simply that there's more and more people in the world that can contact physically much more easily, so the disease can be transferred much more easily over larger distances. On the other hand, less and less people are dying from AIDS, and the reason for that is the discovering of the disease in its early stage, as well as the development of the medicine and keeping a certain routine in the lifestyle that is healthy.

Aleonysh [2.5K]

Answer:

For the 1st block on the left I think there are 2 dominants for that would be BB. The 1st block on the right would be 1 dominant and 1 recessive and that would be Bb. The bottom on the left would be the same as the first block on the right. That would be Bb. The last block that would be the bottom right would be 2 recessives and that would be bb. I hope this might help.

Explanation:

When you are doing punnet squares, you have dominant and recessive traits. There are ways you can do that. If you have 2 alleles of each parent of that offspring, there will be a genotype and a phenotype that represents a genetic trait of each genotype. I hope this helps your question.
