The niche of an organism is the functional role that it plays within an ecosystem. The niche (better refined as the 'ecological niche') is determined by the abiotic factors, which comprise of living features such as animals, plants and fungi, and biotic factors.
This is what I found on the internet hope it helps
I think you are looking for the word, Metaphase.
Answer:
14 problems worth 5 points and 15 problems worth 2 points
Explanation:
x+y=29
14+15=29
5x+2y=100
5(14)+2(15)= 100
70+30=100
100=100
Hope this helps!
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.
