Answer:
convergent evolution
Explanation:
Convergent evolution is a feature of organism to develop similar traits as other animals in order to adapt to their habitat. Similarly to bats and birds both developing "wings".
The thumb-like appendage in a panda is actually a false thumb. Since Giant pandas require a large amount of bamboo to maintain life. They must be very efficient in tearing and stripping the leaves for fast feeding. Pandas that developed this trait were better able to survive and pass this along to their offspring.
1.
Primary Structure : It refers to refers to the sequence of amino acids in the polypeptide chain.
2.
Secondary Structure : Within the long protein chains there are regions in which the chains are organized into regular structures called
Alpha Helix (
- helix ) and
Beta - pleated sheets . Hydrogen bond is present in secondary structure.
3.
Tertiary Structure : The overall three dimensional structure of polypeptide chain is called Tertiary structure.
Hydrogen bonding,
ionic bonding,
dipole-dipole interactions
, Disulfide bonding are present in tertiary structure.
4.
Quaternary Structure : The polypetide chain aggregates and the protein contains more than one amino acid chain. This is Quaternary structure.
Hydrogen bonding is present in them.
Answer:
carbon dioxide CO2
Explanation:
plants need it to produce
The diaphragm,
During inhalation, the diaphragm is contracted which increases the volume of the lung cavity. During exhalation, the diaphragm is relaxed which decreases the volume of the lung cavity
the sugar is callled glucose
