Ascaris is a type of parasitic nematode worm that inhabits the small intestine of its host, which includes humans. The intestine can be a harsh environment for biological material as it is alkaline and contains enzymes to facilitate the break down and absorption of nutrients. The presence of a <span>cuticle can act as a physical barrier, protecting the parasite from these elements.</span>
Answer:
With the development of industry (finally followed by the accelerated connection of settlements), more and more emissions of various gases into the atmosphere began.
Explanation:
Gases, ie particles on which the solar radiation (at least its infrared part) is efficiently dissipated and according to a larger published mechanism additionally warms the planet.
A large number of other gases, such as carbon monoxide and methane, are also taking up more and more space in the air, thus increasing the warming effect of the planet.
These gases do not only destroy the atmosphere directly. Between 30% and 40% of carbon dioxide (and the percentage of others) dissolves in the oceans. This mechanism reduces the pH value of water or increases the acidity.
Answer:
TEE Transesophageal Echocardiography
Explanation:
TEE is an ultrasound of the heart but instead of doing it from the chest it is done by inserting a small probe into the esophagus. Since the esophagus is very close to the heart, it can be seen much better than a conventional echocardiogram. The abbreviation comes from TransEsophageal Echocardiography (TEE).
<span>Answer:
For ectotherms, on the other hand, body temperature mainly depends on external heat sources. That is, ectotherm body temperature rises and falls along with the temperature of the surrounding environment. Although ectotherms do generate some metabolic heat—like all living things—ectotherms can't increase this heat production to maintain a specific internal temperature.</span>
