The case described benefits of the new drug as a low-cost, safe, and simple cure for river blindness. The current residents suffering from this parasite did not have funds to afford alternate treatments like expensive hospital visits or other drug options that are required for a cure. As reported in the reading, the condition is caused by a worm that is passed through the bite of a black fly along the tropical areas of Africa and Latin America. The worm then burrows under the skin and continues to grow up to a length of two feet. As the worm reproduces, it releases millions of offspring that slowly wriggle underneath the skin until invading the eyes, eventually causing blindness.
It will roll into a ball so that its stiff spines are protecting itself. The hedgehog has very poor eyesight. This was surprising for me because it would need could eyesight to be active at night. Instead of its eyes, they use their ears and sense of smell. Hedgehogs are immune to toxins so they are able to eat beetles, wasps, and some venomous
It is shaped like a loosely closed fist. It acts as a filter for the blood taking bacteria and other foreign organisms out of the blood helping prevent infection. However, it is possible to live without a spleen as other organs in the body partly take over its function. Life without a spleen? The main risk to health after a splenectomy is an infection such as septicaemia, as the blood is not being filtered as effectively as it should be.
Influenza is spread from person to person by coughs and sneezes, but the virus doesn't begin its journey in a human host. Instead, wild aquatic birds such as ducks and shore birds perpetuate the influenza viruses that cause human pandemics. Although these birds carry the genes for influenza in their intestines, they usually don't become sick from the virus. And because they can migrate thousands of miles, the healthy birds can spread the virus across the globe even before the microbe makes contact with the human population. As it happens, the form of the virus found in wild birds doesn't replicate well in human beings, and so it must first move to an intermediate host--usually domestic fowl or swine--that drinks water contaminated by the
In fact some farmers thought of them as rats that ate their crops. Tarsiers are sold as pets to people, and are pretty popular, since they sit calmly in your hand (their whole body, that’s how small they are!) When they are hunted by people and put into cages, to be sold, some Tarsiers commit suicide due to the captivity. The Philippine government put Tarsiers on the endangered species list. So there was no hunting of Tarsiers allowed anymore.
In the book it says,“Most parasites live in more than one kind of animal, but they’re all trying to reach their final host, the ultimate vector”(60). Parasites can kill their host but once their host is dead they die along with it in Peeps it says,“One thing about parasites—they’re great at living inside other organisms, but once they hit the outside world, they’re not so tough.”(109) In some ways the parasite situation form the book could be true only some aspects could. The unusual strength, night vision, heightened senses, and an affinity with rats cannot be a realistic benefit form a sexual transmitted parasite. Parasites
Only got about an hour’s sleep, if that because of all the bugs and creatures such as crickets, tree crawlers and monkeys. They just wouldn’t be quiet and there was this little creature that sounded like a mini referee. I Have begun the day with some sago palm tree, completely edible but not as nice as a bacon barm. I changed my socks and put bags on my boots because wearing wet socks can lead to chronic moisture which can cause tissue breakdown and fungus. I knew I had to follow the Amazon River because that was the success story that saved the passengers of a 92 passenger flight in 1971.
This has become a controversial topic for every Manitoban, as there are diverse opinions on its use. However, malathion shouldn’t be banned because it is low in toxicity, it doesn’t bio accumulate, and lastly and most importantly it kills mosquitoes. Unlike DDT, malathion is low in toxicity. This means that it’s effect on the environment and wild life is greatly decreased. There is a lower chance of malathion affecting non-target species and organisms.
Human induced fires are a main threat. They set fires to fields in order to improve fertility for livestock grazing, killing ticks and other insects, making scrap metals visible to collect, and stimulating fern growth. According to the World Wildlife Foundation (2014), “indiscriminate logging, forest fires, and land conversion for farming are the main causes”. Leopards are quite solitude creatures, so not having forests to take cover in is taxing on their existence. An area of about 5,000 km^2 is the last viable habitat in Russia for the Amur leopards (World Wildlife Foundation, 2014).
Bees provide pollination. If bees weren’t pollinating our food, all we’d eat is stuff like “grains and grasses.” By pollinating flowers, it’s helping flowers reproduce. If we didn’t have bees, our plants would die, which would lower the oxygen levels on earth. Bees are dying every minute and if we don’t start saving the bees then we will barely have anything to eat. You can help the bees by planting things that bees like.
