The big question in this chapter is 'are fish intelligent?' Fish have small brains, in fact, they have the smallest brain relati

ve to body size of all vertebrates. Yet decisions are being made, important details and encounters are memorized, mental maps are constructed of a fish's varied environment, and fish learn by watching one another. Could it be that even a small neural circuitry generates intelligence and learning? A premise here, is that if evolution requires it, intelligent circuitry will be assembled in any brain, even ones with a small number of neurons. Now we begin exploring the evolution of intelligence, and trying to understand the ecological and social forces that may require or influence cognitive skills needed for success and survival in such an environment. An important body of evidence is what evolutionary biologists refer to as 'convergence. Many common physical traits are found in unrelated species because their environment and behaviors require them. That bats and birds both have wings is an example. It makes sense then, that convergent cognitive abilities would also arise. If organisms of all kinds share common cognitive skills such as social learning, teaching, planning for the future and inventing tools, then the neural complex necessary for these skills must develop in simple networks available across species. While neural complexity must align with and influence cognitive and behavioral complexity, common cognitive abilities shared by many species must also be possible with relatively simple brains. What fish studies in this chapter provide information about convergence and cognitive functioning? And what about Morgan's Canon? Its sort of like Ocham's Razor for evolutionary psychology - a principle of parsimony stating that scientists should look for the simplest explanation for an animal's behavior

After reading the description attached to the graph represented on the picture, I would say that the resistance gene was present in the aphid population as a result of changes in the aphids’ local habitat by the insecticide. I  consider the second option as a correct one because according to the amount of spreading  of  insecticide<span> per year there was a possibility that it caused a such a change.

lina2011 [118]

Answer:

The correct answer is D. The cytochromes

Explanation:

Cytochromes are proteins which contain tightly bound heme metal which easily undergoes oxidation and reduction and are responsible for accepting and donating the electron. They play an important role in the electron transport chain and helps in formation of ATP during oxidative phosphorylation.

The metal ion provides the capability to the cytochrome to gain and loss the electron. a, b, and c are the three classes of cytochrome out of which cytochrome c is the most abundant and stable.  

Therefore the redox carrier of ETC that have bounded metal atom are cytochromes.

HELP ASAP I WILL GIVE BRAINLIST!!! Read the given chemical reaction.
daser333 [38]

Answer:

4.2moles

Explanation:

"The answer to your question is 4.2 moles of H₂O

Explanation:

Data

moles of H₂O = ?

moles of C₂H₆ = 1.4

Balanced chemical reaction

2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O

Process

To determine the moles of H₂O, use proportions and the coefficients of the balanced chemical reaction.

2 moles of C₂H₆ 6 moles of H₂O

1.4 moles of C₂H₆ x

x = (1.4 x 6) / 2

x = 8.4/2

x = 4.2 moles of H₂O"
