Hair like enzymes are made of protein. However for a protein to be an enzyme it must have a very specific tertiary structure (shape) and have an active site that has a complementary shape to part of its substrate molecule. ie the enzyme must fit with the thing that it breaks down The tertiary sructure of hair is not highly folded and does not have a complementary shape to a substrate molecule therefore it is not an enzyme
What is the term use for when particles leave the cell?
When particles leave the cell is is either through a passive process such as diffusion or an active process called exocytosis.
Should you take your vitamins with orange juice?
most vitamins should be taken with a meal and a solvent...it does not mater if the solvent is water, juice or milk
A study of generally uniform line of Drosophila flies shows that when moisture content is high during development, more flies in the population develop abnormal abdominal phenotype. Therefore greater percent of penetrance is observed with increased moisture. The reverse is the case if the moisture content is low.
Penetrance is the frequency of phenotypic expression of a gene or allele in a family.
Irish moss and sphagnum moss have been used medicinally. The most common use of moss is as a dressing for wounds. It has been used to stop bleeding in field wounds during wars in Scotland and in the Civil War in the United States.
How do you prevent frozen pipes in a rural home where temperatures frequently fall below zero?

Pepsin and trypsin both are protein digesting enzymes.
It's a covalent bond, cuz C H O are all non metals. Covalent bond forms when 2 or more non metals are bonding together
Enzyme decomposition is the process where enzymes break down complex molecules into simpler components. This is an important biological process that allows organisms to obtain necessary nutrients from food, as well as to regulate metabolic pathways by breaking down waste products.

When is it not suitable to use electrophoresis?
Electrophoresis is not suitable for separating large molecules like cells or whole organisms. It is also not ideal for separating molecules that have similar sizes and charges, as they may run together on the gel and not be resolved effectively. Additionally, electrophoresis may not be the best choice when working with samples that require very high resolution or sensitivity, as other techniques may be more appropriate.
-Cellulose is made of many repeating sugar units, as many as 15,000; but -hemicellulose is made of only about 500 to 3,000 sugar units.
-There are many different kinds of hemicellulose found in plant cell walls. Primary cellular walls have predominatly xyloglucan. Other forms of hemicellulose include glucuronoxylan, arabinoxylan, glucomannan, and galactomannan which are found in primary and secondary plant cell walls.
-These molecules are arranged in a less organized waythan regular cellulose and they tend to chemically break apart in acidic or basic conditions.
-They are found abundantly in plant collenchyma cells. These cells have a support function, particularly in young plants. They allow the plant to have support but also be flexible, if bent over the plant (or part) can snap back up.
-Higher levels of hemicellulose in animal feed is favoredbecause the animals will tend to eat less on their own.

Water molecule is polar due to its asymmetrical structure and unequal sharing of electrons between the oxygen and hydrogen atoms. The oxygen atom is more electronegative, pulling electrons closer to itself and giving it a partial negative charge, while the hydrogen atoms have a partial positive charge. This creates an overall dipole moment in the water molecule.

What is the use of starch in pharmaceutical drug preparation?
Medicaments cannot be given as is to a patient. They should be formulated into a suitable dosage form like:
Tablets, Capsules, Mixtures, Emulsions, Draughts, Syrups, Elixirs, Linctus, Drops etc.,
by addition of a medium/vehicle/base.
These excipients form the bulk for the preparation, dilute the medicament to a suitable concentration with a convenient intake volume, mask unpleasant taste or smell, act as binders, may have mild therapeutic action or preservative action.
Tablets are formed by compressing the medicament with a binder, and as you know, with coloring agents, sweeteners (for chewable tablets) etc.
Starch is a common binder for medicaments to form as tablets.
