Answer 1

85.b 2 million years ago

The homo erectus type left the africa in the search of the suitable habitat and food sources , which is around 1.9 years ago.They migrated through crossing the levantine corridor and horn of africa to Eurasia.

86.e none of the above

Basophiles are the white blood cells releases the histamine in respons to the antigens .Alleles are the variant form of the gene and located at the same position either on same chromosoems or same gene locus, in variety of different forms. The diploid organisms have two alleles at gene locus and one of them are inheritable. Telomeres are present at the end of the chromoseomes in the form of repetitive nucleotide sequence that prevents the chromosomes from degradation and fusion with neighbouring chromosomes.

87.similarities between organisms based on descent from a common ancestor

Homology refers to the common ancestry between pair of gene structure in one or more population of the different organisms.For example - The wings in the birds is homologues structure to the forlimbs of vertebrates.

88.d.all of the above

The adaptive radiation refers to the behavioural pattern which causes the certain population to cope up with the surroundings. If one species leaves the area and move into other areas, evolve their trait to survive. It allows the evolution of diverse species from common ancestors.
