with echinoderms and chordates. Pharyngeal slits they share with chordates. Hemichordates are the sister taxon to echinoderms as described by Ambulacraria hypothesis, then gill slits are an ancestral feature for deuterostomes. These gill slits are supposedly lost in in lineage but some researchers have found evidence for gill slits in extinct carpoid echinoderms. The Ambulacraria hypothesis unites echinoderms and hemichordates on the basis of a shared diffuse epidermal nervous system. It’s…

This can be clearly seen in pop music and advertisement. R. Gill argues that ‘women are not straightforwardly objectified but are presented as active, desiring sexual objects who choose to present themselves in a seemingly objectified manner…” She adds that this can be seen in advertising “…The sexually autonomous…

Freshwater Treatment for Amoebic Gill Disease Freshwater treatment for AGD requires checking for few things before and during the treatment to carry out a successful and effective treatment. 1. Freshwater Source: The freshwater source should be checked for temperature, total ammonia nitrogen and ammonia percentage, pH, hardness, salinity and any harmful plankton. Temperature: Freshwater with temperature closer to the temperature that treating fish are being reared in is best choice. Colder…

in the mitochondria. Gas exchange in sharks occurs in the gills, and the gill slits found at the side of the head. Sharks have a high oxygen demand, and oxygenated water constantly has to be flowing over the gill filaments for the respiratory system to work. That’s actually why sharks have to swim while they sleep! Water enters through the mouth and the oxygen from the water enters the gill filaments, and the water then exits through the gill slits. A shark heart is an S-shaped tube with two…

and their blood is not always pigmented (Echinoderms). Crayfish, in comparison, have a heart and gills, which in some cases enable them to breathe on land and in water. When water goes through the gills, the oxygen gets transferred into the bloodstream and the carbon dioxide is then released. In cases of breathing on land, some crayfish have made the adaptation of excreting a liquid onto their gills when out of the water (Writer, L.…

would allow the country to reduce spending, and overcrowding in prisons. Changing the way nonviolent drug crimes are charged and sentenced would also help reduce overcrowding, and make room for people who committed violent crimes. According to Molly Gill, “Lengthy mandatory minimum sentences are cruel, inhumane, and degrading because…

experiment investigating the effects of pesticides on bee colonies, authors Richard Gill, Oscar Ramos-Rodriguez, and Nigel Raine explain that within their experiment, colonies exposed to neonicotinoids sent more worker bees to forage for food than colonies not exposed to any type of pesticide. Pesticide colonies also suffered from decreased worker efficiency despite a greater amount of time and energy focused on foraging. Gill, Ramos-Rodriguez, and Raine concluded that neonicotinoids most likely…

its scales. On its underside it is a light brown. It also has a sharp point at its back end that is a tannish color. It has very sharp points above its eyes, down his back , and arounds its point on its tail. The Tunisa also has very sharp fangs and gills around the head. It also has a long tongue that gives it a perfect sense of smell. I’d say a full grown male can grow up to…

culture within the media through sexual values, identities, and practices. Gill argues that this form of sexualization comes from the rapid representation of western societies, normalizing the concept of pornography within the culture. She views sexualization as an awareness of gender, realization, and class, which works within producing the discrimination to individuals of their age and the ideal of heteronormative. However, Gill refuses to take sides on whether she’s ‘for’ or ‘against’ the…

Harvard University’s Project on Global Working Families and at Mc Gill University-164 have found a way to guarantee paid maternity leave. The only ones that haven’t are Papua, New Guinea, Swaziland, Lesotho and the United States.” Not only does this statement provide specific facts and information pertaining the topic of maternity leave, it also displays the credibility of the information she, herself, researched for Harvard and Mc Gill University. This builds a belief and trust concerning the…
