<span>To prove his Theory of Evolution. After studying the different species of finches he found the Galapagos Islands, Darwin focused on breeding pigeons by selecting specific traits of different individuals (this is mainly a method through which different kinds of dog breeds came about). On the basis of these studies Darwin concluded that natural selection and artificial selection acted roughly in the same way. Darwin's decision to enforce a certain trait represented, in a sense, the selective pressure which is present in a natural environment (the law of the fittest).<span>

When acid precipitation occurs, it effects Earth in a few ways. One way is that when the acid rain soaks into the soil, it removes the nutrients that plants rely on. This, in turn, damages a lot of vegetation. Another way is that it raises acidity levels in water. The higher the acid levels, the more it harms the organisms living in water.
I think this sounds alright

I believe the strength training would be squats.
Squats are considered one of the best exercise for dancers because it train almost all functional muslces needed in the dancing moves simultaneously , allowing the dancers to develop strength in their abdominal, length, and back muscles.
1 It usually contains only one type of producer.
2 It usually contains a great diversity of species.
3 It contains simple food chains that have more consumers than producers.
<span>4 It contains complex food webs that have more heterotrophs than autotrophs.</span>
The correct answer is; D
Homologous structures is the term used to describe physical similarities between related species that indicates a common ancestry.
Homologous structures are structures that have the same form or functions in different animals, indicating that the animals have evolved from a common ancestor. Homologous structures usually appear very similar in form but it may or may not have the same function in the different animals that are suggested to be related. The bones in the front limbs of many different mammals (such as humans, deer and bats) which are similar in their structure and arrangement are homologous structures.
