The given statistics indicate the comparison of the genome of the various organisms. Genome can be defined as the complete set of the genetic material (chromosomes/genes) present in the cell of an organism, or, the haploid set of the chromosomes which are present in an organism's gamete cell. Since, the given statistics are comparing the percentage of the genetic material which is similar among different organisms, the blank can be filled with 'genome'.
When Phospholipds are mixed with water , they spontaneously rearrange themselves to form the lowest free- energy configuration. this means that the hydrophohobic regions find ways to remove themselves from water , while the hydrophilic regions interact with water. the resulting structure is called a lipid bilayer.
Arranging data in rows and columns is a table
Complementary pairing goes like this:
A pairs with T and
C pairs with G. Nothing about this changes unless you get to mRNA (But we won't go into that) :)
So if you have a strand that goes TCG GA then your pairing will look like this:
T A
C G
G C
G C
A T
Hope this helps!! :)
