Biology is a branch of science that studies the nature of life from the smallest parts of living things to the largest plants and animals. Ask and answer questions about the living world and its wonderful inhabitants in this category!
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
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...
Such organisms are called decomposers, which include micro fungi
and bacteria .
They decompose dead and decaying organic matter.
An organism that decomposes decaying organisms leaf litter and
other types of dead organic matter is called a saprobe, saprotroph
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.
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...
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.
This is a very simple question with rather a complication set of
friendus. 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
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.
1. Familiarize your self with the laboratory.
2. Use common sense.
3. Use a safety gear when necessary - particularly eye
4. Follow the instructor's or teacher's directions.
5. Practice correct or proper procedure in handling liquids.
6. Never smell a liquid reagent directly .
7. Never pour a reagent back into main bottle .
8. Don't eat or drink in the lab.
9. Use fuming hood while working with volatile liquids .
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
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...
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
A carrier would have to by heterozygous. Carriers don't express
the "carried" allele but have it nevertheless. This means it has to
have one allele of each. For example, if a trait has alleles A
(dominant) and a (recessive), the heterozygous genotype will be Aa
and will display the dominant phenotype (unless the trait is a
special/more complex type of expression like incomplete
Well, yes and no. Plants take in CO2 and release oxygen during
the day, however during the night it does the opposite, it takes in
oxygen and releases CO2. This is why it is good to have plants in
your house during the day but not in the night. Make sure you take
it out of your rook so that you can have a better nights sleep.
PGAL is more commonly know as G3P, or
glyceraldehyde-3-phosphate. It is the final product of the Calvin
Cycle, or the dark reaction in plants. Two G3P molecules, which are
each 3-carbon compounds, go on to create glucose. RuBP is ribulose
bis phosphate . It is an organic compound used in Calvin cycle, it
is used to fix CO2 during Calvin cycle . where one CO2 molecule is
covalently bonded to RuBP to form an unstable intermediary compound
that later breaks down by...
