Answer:
Sowbugs and pillbugs are similar in appearance and their names are sometimes used interchangeably. However, the sowbug has a pair of tail-like appendages which project out from the rear of its body, while the pillbug has no extreme posterior appendages, and can roll up into a tight ball when disturbed.
Explanation:
It is true that rock layers can be correlated to each other by using fossils and matching layers.
This is because these rocks have similar, if not the same layers, which can easily be determined by the fossils that may appear on them and just using them to match the layers to see if they can correlate.
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: Despite the fact that we have gobs of prokaryotic cells living inside and on us, humans are still categorically eukaryotic organisms. This means that all human cells—including those found in the brain, the heart, the muscles, and so on—are also eukaryotic.
