Great Question! Mass is basically how heavy Something is. Most people confuse mass with weight but there very different from each other. Weight is the downward force something has because of gravity. Mass can be measured in a variety of units too. The second part of the question is how it affects density. It affects it because to find the density you need to be able to find the mass since the formula is Mass divided by volume. I hope this helped you understand a little bit more about mass. Have a great day!

Answer:
Scientist are worried about the future of some animals because their number and genetic diversity both is very low.
Genetic variation in the organism of the same species or different species provides the stability for the survival.
Even if the number of organism increases its stability will be low because the genetic variation of those organism is low.
So, even after their number increases they can die due to less variability so genetic variation is equally important as like that of population size.
