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.
Answer:
Because Lumbricina ( Earthworm ) Is a living, breathing, animal
Explanation:
Orchids are now grown through vegetative propagation, rather than seeds, courtesy of developments in cloning. This allows many orchid plants to be grown from a portion of a single orchid plant. This allows even the rare orchid o to be grown in mass. There is also little variation when cloning s done as compared to growing with seeds.
Answer:
The correct answer is "mutations to homologous genes".
Explanation:
The missing options of this question are:
A) morphology.
B) the pattern of embryological development.
C) biochemical pathways.
D) habitat and lifestyle choices.
E) mutations to homologous genes.
The correct answer is option E) "mutations to homologous genes".
Modern cladograms do not use physical characteristics to establish evolutionary similarities among species. Modern cladograms are constructed from evidence from molecular systematics based on similarities in mutations to homologous genes. The more similar are the homologous genes, the less different their genetic sequences are, and are considered more closely related in their evolutionary tree.
Explanation:
they are native plants in their new ecologies
