Plants reproduce through the
process of fertilisation. Fertilisation is the process where female and male
cells join together to form an embryo inside the seed. The seed protects the
embryo in preparation for germination when conditions permit the plant to
produce new plants.
Seed plants are classified into
two types to determine reproduction. First are the Angiosperms, this type of
seed plant has flowers that have special structures for reproduction. Pollens
are made by male cells, while ovules are made by female cells. Pollens are carried
out through the process of pollination (e.g. wind blows, insects carrying
pollen). Most angiosperms that don’t undergo pollination develop intro fruits.
If it goes into pollination they become new flowering plants.

Second classification is the
Gymnosperms, which are seed plants that are held in cones. Gymnosperms like
Angiosperms also have male and female reproductive cells. Reproduction also
occurs through pollination but most gymnosperms are trees. The best example of
a gymnosperm are pine cones. </span>
Natural selection is an evolutionary mechanism by which (B.) advantageous traits become more common in a population.
Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall. There is also a wide range of skin color across people. Skin color is also a polygenic trait, as are hair and eye color.
All the above:
Eye color
height
skin color
I think the correct answer from the choices listed above is option A. During gene expression, a cell reads the instructions in dna and builds a protein based on those instructions. Gene expression <span>is the process by which information from a </span>gene<span> is used in the synthesis of a functional </span>gene<span> product.</span>
