Answer:

1. Population change is modeled and explained in a model that shows natural growth or anexponential growth model. This comes along with the changes in population size and agedistribution within the population

2. Governments may promote population change in many ways. One way is to limit the number of children citizens can have. An example of this was China’s One-Child Policy, a law where the Han Chinese (primarily living in urban areas) cannot have more than one child. This drastically affected China’s population as now there is a huge male and elderly population. Another way is to push for the usage of contraception. In Iran, contraceptives have been used more and have been endorsed by the government to limit an unbalanced population.

3. One environmental effect of human population growth is the problem of global warming. Some people are scared that global warming will lead to rising sea levels and extreme weather conditions in the future. another is deforestation, in order to support the growing population, forests are being destroyed at an alarming rate.

Why have we not found examples in the fossil record of every animal that ever lived on earth? select all that apply. select all

Reptile [31]

Many fossils remain buried
Rocks contain the history of life...

Btw the animal ones don't count i think cuz fossils can be anything like teeth, bones or anything not just animals it can be formed by leaves as well so just for extra guidance i believe the ones that state animals are probably not the options to choose due to the fact that fossils are not just living organisms they're anything that has been buried and decomposed over many years and layers of sediments cover it over many years compression may alter the shape of the fossil aswell!

Hope that extra info helps for a bit of guidance!
