Asked in Biology, Skeletal System

What are examples of hinge joints?

The most typical hinge joints is the elbow, which attaches the Humerus to the Radius and Ulna. Some say the interphalangeal joints between the bones in your fingers are hinge joints; others call them condyloid joints Hinge joints that are a bit atypical, as they allow some limited rotation include the: knee, or tibiofemoral joint. This is the largest hinge joint. The patellofemoral joint, between the kneecap and thighbone, is not a hinge joint.. The knee is sometimes considered a modified hinge joint or...

What is the biological and medical term meaning maintenance of a stable internal environment?

Homeostasis is basically biological term also used in medical field . It is defined as maintenance of internal conditions constant or nearly constant . It includes three basic processes . 1 : Osmoregulation. It is keeping balance of water and electrolytes in body which occurs with help of kidneys which are major osmoregulatory organs . If a person consumes more salts , it results in increased thirst which , increased water usage and production and elimination of extra salt to maintain osmotic pressure of...

Asked in Biology, Physics, Chemistry

Which science is the most complex chemistry or biology or physics?

Biology is the most complex because it deals with living organisms and number of known organisms is more than two and a half million while un-described species are estimated up-to 30 million . each organism is different from other and has its peculiarities . Chemistry deals with matter, with 92 natural element and nearly thirty synthetic elements . Number of organic molecules is quite large but much less as compared to species. ...
Asked in Dolphins and Porpoises, Biology, Zoology or Animal Biology, Taxonomy

What do Humans and dolphins have in common?

Both are mammals, so both have mammary glands, and hair on their skin, and they have 7 cervical vertebrae as humans do. They are touted to be one of the only 3 animals that mate for pleasure (humans, dolphins, bonobos), and socially with many partners as many humans do. They also mate face to face unlike other animals. Dolphins do give birth to live young, and as mammals, they nurse their young with breast milk. They have very high communication skills amongst...

What are some benefits of DNA data banks?

Most DNA databanks contain data from non-human organisms like animals, plants, bacteria and viruses. This information is used in basic biological research and medical research. Some specialized DNA databases exist for other purposes Previous answer: They help law enforcement agencies to identify and prosecute criminals using genetic evidence gathered from crime scenes. Also, they are used by doctors and hospitals to establish relationships like Paternity test. ...
Asked in Biology, Temperature, Circuits

Why does absorption of a membrane increase with temperature?

This is a very simple question with rather a complication set of answers. Movement of some molecules or substances across a membrane only increases between the temperatures of 1 to 37 degrees Celsius (in most organism/cellular systems). At temp. greater than 37 Celsius the membrane proteins involved in transport become denatured. One has to consider the main processes of movement of substances across a membrane i.e ranging from passive diffusion and osmosis and including active transport systems and end/exocytosis etc. ...

What is the GC content of a human genome?

40% This also lets us know that the AT ratio is 60%
Asked in Biology, Fossil Fuels

What is the solute and solvent in gasoline?

I'm not sure what you mean, commercial gasoline is a blend of linear and aromatic hydrocarbons averaging about 8 carbon atoms per molecule with various additives for various purposes (e.g. keep engine clean, reduce pollutants, stabilize mixture, improve starting in cold weather). Gasoline is a solvent, but if you was a solvent for cleaning parts there are far safer ones that work as well. ...

Asked in Biology, Noble Gases

How are gases unique?

Gases can be compressed with little force used. Solids and liquids are virtually incompressible. If you were to set up an apparatus that allowed you to increase the pressure inside a vessel, it would be noted that the volume of the liquid and the solid would change very little, but the volume of the gas would decrease. This is due to the intermolecular forces between the individual molecules. ...

What do glycolipids do?

Glycolipids may be involved in cells signalling that they're ''self''; to allow the immune system to recognise them. They could also be hormone receptors Glycolipids are a carbohydrate with lipids attached. Their main function is to provide energy and to serve as markers for cellular recognition. Glycolipids are found in cell membrane animals tissues and nerve cells, composed of lipids and carbohydrates such as glucose or galactose as in cerebrosides or combination with sialic acids in gangliosides. It provide energy as well as cell...

What is the main difference between plant and animal cells?

Plants cells have a cell wall over the cell membrane,whereas,animals cells lack cell wall. In plant cells, there is a single large vacuole present in the middle, whereas, in animals cell,there are more than one vacuoles. Plant cells possess plastids, but, animal cells don't. Animal cells have centrioles, whereas, plant cells don't.
