Answer:
D. sulfur oxides from factories
Explanation:
This does not naturally occur, only if there is a factory. These other things happen on their own in nature but sulfur from factories relies on other factors down on earth.
Answer:
C. Look at the Y chromosome because it is paternally inherited.
Explanation:
According to the given information, mitochondrial DNA study reveals that Neanderthals did not impart any genetic sequences in modern humans but the study of the whole genome contradicts it.
Mitochondrial DNA is maternally inherited, if whole-genome studies show the input of genetic sequences from Neanderthals in modern humans, the male Neanderthals might have shared some sequences with modern humans. In human, the Y chromosome is inherited from father to son.
So, if only male Neanderthals share common genes with modern humans, the study of genes present on the Y chromosome could reflect the sequence homology between the two. If there is no sequence homology between them for the genes of Y chromosomes, the hypothesis that male Neanderthals have imparted gene sequences in modern humans should be rejected.
Answer:
"A model that shows global systems, the processes that operate within each system and the ways those systems and processes interact."
Explanation:
In the global system mainly four types of models interact or co-ordinate between each other. When we take an example of the ecosystem, these four models can be predation, parasitism and herbivore. Interaction takes place in such a way that one model gets the benefits while the other one gets affected. But when talk about mutualism, both of them gets benefited from the interaction. The basis of the global system property is firstly made by the species interaction.
