Answer:
C) Most coniferous trees have both male and female cones.
Explanation:
- Unlike flowering plants, conifers do not bear flowers. instead of flower they bear male and female cones.
- The male cone produces the pollen and the female cone contains ovule which develop into seeds.
- The reproductive cycle of a conifer begins in the spring when the male cone releases pollen in the wind and these pollen get trapped in the scales of female cones.
- These pollen goes through a resting period and then fertilizes the ovule.that matures into seed.
- The seeds of conifers are naked. i.e. not enclosed

Answer:
Theories are ideas and supposition used to explain something, a law is a system of rules in place to regulate actions of their members. Theories are something that can be bent and changed at will. Laws have to be judged in court before someone can change them.
Answer:
Phylogeny: It is related to evolution dealings in the evolutionary development of a species. It is represented by different ways vertical or slanted.
Phylogenesis: It refers to the evolutionary relationships among species.
Phylogenetics: It is determination or estimation of evolutionary relationships among groups of species, organisms and genes.
Phylogenetics is a field of biology which is used to find relationships among different organisms. This relationship is showing through a tree (used to model actual evolutionary relationship of organisms). Ancestral divided into two descendant species because closely related organisms are shown in near branches. If there is too much divergence between two species its mean they are not closely related.
The history of speciation (one species becomes divided into more than one new species) tells us how these species are related to each other. If they evolve to be separate species relatively recently then they are "closely relative" similarly if they evolve to be separate specie long above then they are "distant relatives". For example orthologs are genes in different species that evolved from common ancestor gene by speciation; they retain same function in the course of evolution.
