Answer:
Try B. C and D are helping stop global warming and A isn't as much of a factor
Answer:
they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes
Explanation:
G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.
We haven't found evidence of life yet.
But it would be dependent on geography and planet structure because not all places are easy to live in.
Answer:
C. Genes that are close to each other on a chromosome are often inherited together.
The change where they didn't only have boys anymore but had a boy which was born was more likely due to the fact that there is generally a 50:50% chance of whether a boy or a giril will be born for any given family.
