His mouth is usually lined up so that it doesn't look like he has an underbite, as he does in this picture. Notice that his head looks thick (top to bottom) all over.

This dog means the world to me especially because he’s always smiling since he has an underbite

90.Common Name- Channel Catfish

a.Scientific Name- Ictalurus punctatus

e.Why- The Arizona State Parks website says that Patagonia Lake is only stocked with channel and flathead catfish. This is not a flathead catfish because it does not have an underbite.

جلوزدگی دندان های فک پایین به دلایل گوناگونی ایجاد می شود. شایع ترین دلیل ایجاد آن مشکلات ژنتیکی است. درمان جلوزدگی فک پایین از این جهت مهم است که علاوه بر ایجاد مشکلات روحی و روانی باعث به خطر افتادن سلامت جسمانی فرد نیز می شود. درمان این عارضه بسته به نوع شدت آن و سن بیمار متفاوت است.

ارتودنسی فقط مربوط به دندانهای صاف نیست. ممکن است گاهی اوقات فک بالا یا پایین با صورت شما مطابقت نداشته باشد و درست به نظر نرسد ، از این رو دندانهای شما به درستی روی هم قرار نمی گیرند. به عنوان مثال ، فک پایین خیلی عقب است و باعث می شود دندانهای بالایی شما خیلی جلوتر به نظر برسند. اصلاح کننده های فک یا وسایل کاربردی در این زمینه می توانند در اکثر موارد جلو بودن فک پایین را اصلاح کنند اما این به سن شما و نیازهای درمانی مربوط به فک شما بستگی دارد.

با استفاده از روش های تقویت استخوان که یکی از آن ها پیوند استخوان است می توانید زمینه ی لازم را برای کاشت ایمپلنت دندان را فراهم کنید.

علاوه بر این، بیماری هایی مثل سرطان، دیابت، مصرف الکل و سیگار و یا بیماری های غیرطبیعی پریودنتال می توانند روی ایمپلنت دندان جلو تاثیر بگذارند پس اگر دچار چنین بیماری هایی هستید باید حتما قبل از ایمپلنت دندان های جلو با پزشک خود مشورت کنید.

تغییر چهره به وسیله جراحی فک و جراحی اصلاحی فک در بیماران با مشکل جلو بودن فک پایین غالبا طیف گسترده ای را در بر می گیرد.

The pacu is often misidentified as a piranha. While in the same family, they are different fish with far different behaviors. Pacus can be found in tropical and subtropical South America. They prefer lakes, rivers, floodplains, and flooded forests located in the Amazon, Orinoco, Río de la Plata Basins, São Francisco River, and in the Guianas. Generally speaking, these fish are listed from Least Concern to Endangered, based on the species of pacu.

First the Stats...

Scientific name: Piaractus

Weight: Up to 88 lbs.

Length: Up to 3.5 feet

Lifespan: Up to 15 years

Now on to the Facts!

1.) While related to piranha, there are several distinct differences that set them apart. For instance, the teeth of a pacu are square and non-serrated. Whereas the piranha has sharp and pointed teeth.

2.) Another difference is that pacu are omnivorous (eat plant and animal matter) and have a more docile temperament.

3.) Pacus also have less of an underbite and sometimes even a slight overbite.

4.) Finally, pacus get much larger than their sharp-toothed cousins.

5.) Pacus and piranhas are actually a characin fish, meaning that they are a type of tetra. Yep. The peaceful community fish you see in pet stores, the world over.

But wait, there's more on the pacu!

6.) They are classified into the Serrasalmidae family. This means "serrated salmon family" and is in reference to the serrated keel running along their stomach.

DOMESTICATION

Our Furry Companions

Artificial selection in dogs has created many dog breeds, but they all have a wolf ancestor.

Dogs and cats were first drawn to people as sources of food—either directly receiving food from humans or indirectly by catching rodents in stored grain. Humans have bred dogs for companionship, protection, and for hunting, herding, and pulling sleds.

1. Gray wolf

Canis lupus

The wolf is the ancestor of the dog. Dogs were the first domesticated animals. The dog is the only animal that has been domesticated on all continents since ancient times.

2. French bulldog, a domesticated dong breed

Canis familiaris

Note the shortened nose and underbite of the bulldog. This breed was selectively bred to fight bulls.

3. Greyhound, a domesticated dog breed

Canis familiaris

Greyhounds have been selectively bred for high-speed pursuit. Their elongated snout and small ears are thought to make the head more aerodynamic.

4. Papillon, a domesticated dog breed

You're unlikely to confuse a wolf with a Papillon.

AGRICULTURE

Natural History of Maize

From humble beginnings, maize, or corn, became a staple food in the Americas.

Teosinte (tay-o-SIN-tee), the wild ancestor of maize, doesn't look much like modern corn. Over thousands of years, through artificial selection and use by humans, maize has become the most important food crop of the Americas. Maize is found with archaeological remains and is deeply integrated into human culture.

5. Aztec goddess with maize

190 to 152 CE, Morelos, Mexico

This female figure holding maize is from the Aztec culture of central Mexico about 600 years ago. Goddesses of maize and other grains are linked to the harvest and fertility, and occur worldwide.

6. Teosinte

Zea mexicana

Teosinte, the ancestor of modern corn, grows wild in Central and South America. In the 1950s, scientists at the Connecticut Agricultural Experiment Station grew these ears from kernels from Huixta, Guatemala.

7. Charred maize

Zea sp.

Plants charred by fire can be preserved for thousands of years. Archaeologists have recovered ancient maize spanning spanning 8,000 years of the history of its domestication.

8. Maize effigies

Ceramic

Inca, dates ?, Highlands, Peru

Maize was significant in the everyday life of many cultures.

9. Maize cultivars

Zea mays

Several varieties of maize--flint corn dent corn, sweet corn, and popcorn--have been bred for different uses. Most of the corn grown in the United States is for animal feed. It is genetically engineered for optimal yield and resistance to pests and diseases.
