Answer:
In the cardinals, if the females start using a different criterion than the color of the feather when they choose couple, most likely to happen is that decreased variation in the shades of red because no form of the trait is advantageous.
Explanation:
Options for this question are:
- <em>Increased variation in the shades of red because the selection pressure has been relieved.</em>
- <em>Increased variation in the shades of red because the cardinals try different ways to impress the females.</em>
- <em>Decreased variation in the shades of red because no form of the trait is advantageous.</em>
- <em>Decreased variation in the shades of red because the only reason for variation was selection pressure.</em>
In the context of natural selection, male cardinals court females using the coloring of their feathers as a form of sexual selection. This means that the shades of red in the feathers are a selection criterion in these birds, and the more visible shades represent an advantage.
But, if the selection criterion was not the color of the feathers, this trait would no longer represent an advantage in the competition between the males to be chosen as a mate. Instead, the trait that would determine sexual selection would be the one that experiences an increase in its variation<em>.</em>
Hello!
Yellow = Y
Green = y
Based on the fact that 25% of the offspring inherited two recessive alleles (we know this because in order for a recessive allele to be expressed, it must be homozygous),<u><em> the parent peas had to both be heterozygous. </em></u>
Yy * Yy will always result in:
1/4 = yy
2/4 = Yy
1/4 = YY

A class of lipids called prostaglandins is typically produced at the sites of injury or infection and is used to treat both disease and injury. They regulate functions like blood flow, blood clot formation, inflammation, as well as labor induction.
Arachidonic acid, from whom prostaglandins are generated, is what causes inflammation:
- In synthetic form, prostaglandins are used to induce labor and give birth.
- They trigger uterine contractions and have a ring structure with at least two or three and perhaps more carbons.
Effects of prostaglandins in the body are
- The hormone that circulates and regulates the kidney's reabsorption of sodium. Prostaglandins, which seem to be present in high concentrations, directly affect nerve terminals to induce pain.
- The production of the inflammatory response is significantly influenced by prostaglandins. Their production is markedly increased in inflamed tissue, therefore they help to produce the essential symptoms of acute inflammation.
- NSAIDs (which inhibit cyclooxygenase) as well as COX-2 selective inhibitors, sometimes known as coxibs, were examples of prostaglandin antagonists. Cyclopentenone prostaglandins as well as corticosteroids, which block the formation of phospholipase A2, might help to reduce inflammation.
