Suppose scientists could compare the dna of modern humans from around the world with the dna of homo erectus populations from the humans’ native homelands. if dna samples from each modern human were found to be most similar to the homo erectus dna from their homeland, that finding a. support the multiregional model.. b. support the out-of-africa model.. c. support both the multiregional model and the out-of-africa model.. d. disprove both the multiregional model and the out-of-africa model.

The correct answer for the blank is-

a. support the multiregional model.

Multiregional model is a scientific model that provides explanataion of pattern of evolution of modern humans. It is an alternative explanation of Out of Africa model.

According to this model, modern humans that are present around the world (that in various regions or multiregions of the world) show similarity to the Homo erectus found in Africa.

In other words, species of human beings first originated in Africa as Homo erectus, which then underwent subsequent human evolution upon dispersing in various regions around the world. These species include all archaic forms of human like Homo erectus, Neanderthals, and evolved worldwide as Homo sapiens ( modern human forms).

Thus, option a) is the right answer.

i dont know this but ask your teacher for !

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
