DNA replication needs to occur because existing cells divide to produce new cells. ... So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!
Digestion and Absorption
Mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use.
Answer – Repetitive Transcranial Magnetic Stimulation (rTMS)
Repetitive transcranial magnetic stimulation (rTMS) is a type
of brain stimulation therapy used in the treatment of depression and anxiety;
it’s most especially used for the treatment of severe depression. During the
procedure, a magnetic field generator (coil) is placed near the head of the
person to deliver repeated pulses of magnetic energy.
Answer:
Through glycosidic bond.
Explanation:
Disaccharide:
Disaccharide is simple polysaccharide. It is formed when two monosaccharides combine together. The monosaccharides are combine through dehydration reaction as a result glycosidic bond is formed between two monosccharides with removal of water molecule.
The reaction is also called condensation reaction.
There are two types of disaccharides:
Reducing disaccharides
These are hemiacetal and have reactive carbonyl group. They can be oxidized to other products.
Non - reducing disaccharides
These are acetals and can not be easily oxidized like reducing disaccharides.
Glycosidic bond:
It is covalent bond formed between the carbohydrate and another molecule such as monosaccharide.
This bond can be alpha or beta glycosidic bond.
