Answer:

The correct answer is - (3) natural communities replacing each other in an orderly sequence

Explanation:

In this diagram, there is ecological succession occurred, the process of the new natural community over the older natural community in an orderly sequences.

In this case, there are change from an aquatic ecosystem to new land ecosystem by changing various biotc and abiotic factors. The ecosystem go through various changes and physical changes.

mote1985 [20]

Answer:

The recombinant frequency between T and S is  18%;

The correct Sequence of genes is T-A-S

Explanation:

The table below shows the recombinant frequency between heterozygous height and nose morphology:

Tall-uptrend snout                            40%                            Expected

Dwarf-downtrend snout                   42%                            Expected

Dwarf-uptrend snout                         9%                             Recombinant

Tall-uptrend snout                             9%                             Recombinant

Sum Total                                           100%

To calculate the recombinant frequency; we have :

=9+9

=18%

Hence, the recombinant frequency between T and S = 18%

The determinant of the corect sequence of the genes is  T-A-S
