35 years
Explanation:
The rule of 70 will be applied here as the growth is steady by some percentage. It is yearly growth in per-cent "/70 Knowing the doubling time for 2% from the chart it is easy to determine the years taken to double the population by the given rate.
Td (doubling time) at 2% is 35
Also,
dividing 70/2
= 35
So in 35 years the population will be double in 2 years at the rate of 2% increase.
The right options are;
A. radial symmetry
B. acoelomates
E. asexual reproduction
F. sexual reproduction
Cnidarian are organisms that belong to the phylum; Cnidaria. Almost all cnidarians are marine animals, and there are several species which include the corals, jellyfish, sea anemones, sea pens, sea fans, hydras, and sea whips. The body form of the cnidarian is radially symmetrical with their mouths covered by tentacles. Many species of cnidarians possess complex cycles of asexual polyp stages, while some reproduce sexually. Cnidarian have many modes of feeding which include; parasitism, taking nutrients from symbiotic algae within their cells, and predation.

Alleles can be recessive or dominant, when this happens the dominant allele is expressed. However, neither a nor b blood group is a recessive allele, so both are expressed in the individual.
