Mr. Morales is teaching a lesson on classification. He says that spiders are classified as a different group of insects because

they have eight legs instead of six legs. He explains that spiders evolved first. Mr.Morales also says that having eight legs is the derived trait that seperates the two groups. Antonio thinks Mr.Morales is wrong. Which piece of information is Antonio considering?

If spiders evolved first, six legs is the derived trait
ss7ja [257]4 years ago
3 0

Answer:

Antonio is right Mr. Morales considered eight legs to be a derived trait when it is an ancestral one.

Explanation:

If spiders evolved first then having eight legs is an ancestral trait and having six legs is a derived one. Mr. Morales says that having eight legs is a trait that separates the two groups which may be correct, but it is an ancestral trait, not a derived one because organisms with eight legs cannot derive from a six-legged ancestor. Rather it is the opposite. That is the piece of information that Antonio is considering.

Why to introduced species thrive and multiply so easily in their new habitats
PolarNik [594]
Actually depends on the species. Take snakes for example. They quickly thrived here in america because they had similar environements over in europe. The warm climate here in florida is perfect for them. They like the heat of the sun the dense foliage and many other good qualities here. Also their are other places that are good as long as they are hot have water and prey and a nice hole they can sleep in they can survive making them very adaptable.

Incorporation of _____, a neutral antibiotic, into a polyvinyl chloride membrane allows for the manufacture of an ion-selective
Alja [10]

The incorporation of valinomycin, a neutral antibiotic, into a polyvinyl chloride membrane allows for the manufacture of an ion-selective electrode that is highly selective for potassium.

<h3>How Valinomycin Ionophores Enter and Transport K+ across Model Lipid Bilayer Membranes?</h3>

  • A biomimetic lipid membrane attached to the surface of the gold electrode contained the cyclic peptide valinomycin.
  • The ionophore characteristics of the peptide were investigated using electrochemical impedance spectroscopy, and the conformation and orientation of the antibiotic valinomycin within the membrane were identified using polarization modulation infrared reflection absorption spectroscopy.
  • By forming a complex with potassium ions and an ion pair with a counter anion, valinomycin transports ions across the membrane, and the combination of these two techniques revealed novel information about the ionophore mechanism.
  • The ion pair is located inside the hydrophobic portion of the membrane and makes a little angle of around 22° with the surface normal.
