While foregut fermentation is generally considered more efficient, and monogastric animals cannot digest cellulose as efficiently as ruminants, [5] hindgut fermentation allows animals to consume small amounts of low-quality forage all day long and thus survive in conditions where ruminants might not be able to obtain nutrition adequate for their needs.
Proteins are the basis of many animal body structures (e.g. muscles, skin, and hair). They also form the enzymes which control chemical reactions throughout the body. Each molecule is composed of amino acids which are characterized by the inclusion of nitrogen and sometimes sulfur. The body requires amino acids to produce new proteins (protein ...
Mutations of proteins that hold the cells of the skin together can cause disease. Autoantibodies against proteins that hold the cells of the skin together can also cause disease. Conditions caused by mutations in or antibodies against junctional proteins found within the epidermis of the human integumentary system.
A large percentage of herbivores also have mutualistic gut flora made up of bacteria and protozoans that help to degrade the cellulose in plants, [1] whose heavily cross-linking polymer structure makes it far more difficult to digest than the protein- and fat-rich animal tissues that carnivores eat.
The eastern lowland gorillas and mountain gorillas were previously thought to be two of the three subspecies of one single species, the gorilla (Gorilla gorilla). However, genetic research has shown that the two eastern subspecies are far more closely related than the western subspecies: the western lowland gorilla ( G. gorilla gorilla ), which ...
“I want you to write down the name of every single person you’ve had unprotected sex with.” The nurse held out a pen. She was stern and no-nonsense.
According to a 2004 report there were only about 5,000 eastern lowland gorillas in the wild, [3] down to fewer than 3,800 in 2016, [4] compared to over 100,000 western lowland gorillas. However, a survey in 2021 gave an estimate of up to 6,800 suggesting the decline was not as bad as feared although they are still facing severe threats. [ 5 ]
The flu can be extremely uncomfortable, and cases can last longer than expected. The average influenza case lasts five to seven days, according to Stockdale. Common symptoms include fever, body ...
