Answer: D. gully erosion
Rill erosion can eventually evolve into gully erosion. Gully erosion happens when runoff concentrates are flowing in a very strong manner causing it to move some of the soil particles. Advanced rill erosion can become a gully erosion.
Answer:
Chloroplasts
Explanation:
Chloroplasts absorb sunlight and use it with water and carbon dioxide to make food.
Answer:B
Explanation:
Agonist-induced desensitization involves phosphorylation of G protein-coupled receptors by two currently recognized classes of serine/threonine protein kinases. Second messenger-dependent kinases, phosphorylating a variety of proteins, mediate a generalized cellular hyporesponsiveness termed heterologous desensitization. G protein-coupled receptor kinases (GRKs) phosphorylate specifically agonist-occupied, or activated, receptors, and thereby initiate receptor-specific, or homologous, desensitization.
Answer:
Explanation:
Cyanobacteria are sometimes considered algae, but they are actually bacteria (prokaryotic), where the term "algae" is now reserved for eukaryotic organisms. They also derive their energy through photosynthesis, but lack a nucleus or membrane bound organelles, like chloroplasts.
