Answer:
Where are the choices?? Wish I could help :(
Explanation:
"Simple" actions like answering the phone are the result of the orchestrated activity of billions of neurons sending signals to each other.
Tracing this to individual neurons is a bit like asking "how does the activity of individual transistors enable my computer to do a simple action like showing me a web-page?"
The layers of complexity that connect the individual elements to seemingly "simple" behaviors is immense. In the case of computers, we understand in precise detail how all the layers work because we designed them. In the case of the brain, there is still much to figure out. We know in considerable detail how biological cells work from the activity of individual molecules, but we still have much to learn about the brain and its relationship to the activity of neurons.
Answer:
the results were published in a peer-reviewed journal.
Explanation:
When the results of any study or a research is published in a well renowned and a peer reviewed journal, then the study is considered to be credible and authentic and is accepted by the intellectual society.
In the context, two young scientists are performing an experiment on the direction finding or the orientation finding abilities of the loggerhead sea turtle which are hatching under the varying magnetic fields.
The finding of these experiment or the result will be considered credible only when the results of the experiment will be published in a peer reviewed journal.
Answer:
Darkened shapes are recessive
Explanation:
In the pedigree shown, we can see that 2 parents that are unshaded shapes have 2 children that are shaded shapes. This would be impossible if shaded shapes were dominant and unshaded shapes were recessive. This is because parents that have a recessive trait have 2 of the same alleles. So if 2 parents that both have a recessive trait have a child, the child will definitely have that trait. But we can see that this is not the case, the parents have 2 offspring that have different phenotype from the parents. This must mean the parents are heterozygous, meaning that they both have 2 alleles that are different. The dominant allele masks the recessive allele, so the dominant allele is expressed. In this case, the children inherited 2 recessive alleles, 1 from each parent, making them have a different phenotype from the parents.
The greater amount of eumelanin in darker skin protects folate from being broken down by UV radiation and thus increases fitness among populations in high-intensity UV areas. ... However, it does not explain why there is variation in human skin color.
