Which correctly distinguishes between a pine tree and an apple tree? the pine tree bears flowers; the apple tree does not have any flowers. the pine tree has unprotected seeds; the apple tree has seeds in fruit. the pine tree is vascular; the apple tree is a seedless, nonvascular plant. the pine tree thrives in warm climates; the apple tree thrives in cold climates.

The right answer is The pine tree has unprotected seeds; the apple tree has seeds in fruit.

Pines are gymnosperms, which means that they have no strict sense of flower or fruit, unlike angiosperms such as apple or oak. The fundamental difference between the true flowers of the latter and the false flowers of the gymnosperms is the presence in the first of an envelope (the carpel) around the ovules which is transformed after fertilization into fruit.

The pine tree has unprotected seeds; the apple tree has seeds in fruit.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
